Sony KDF-46E2000 - Screen Goes Blank

Hi, I have this TV that I purchased around November 2006 and I just started getting the problem. I was watching TV when out of nowhere the screen went blank and then a second later the sound cut out so there is nothing on the screen but the green POWER light blinking. It looks just like what happens when you first turn on the tv.

I pressed the power button and the green light went off and the fan stopped going. I waited a little and then turned on the TV and it worked for a few minutes and the same thing happened. This time I just let the screen stay blank and the green light blink, and after a while the green light went away and a solid red one came up under LAMP. I pressed the power button and the TV came on for a few seconds before the screen went blank and the green POWER light started blinking.

I guess the lamp is the problem, but I'm not sure as I can't find the manual. Does the lamp only last this short amount of time or is this another problem?

    This just happened to my TV last week.  It is about the same age.  when the lamp goes out does your sound go also?  Mine did. If it is just a lamp problem, can I replace it myself?

    SAME EXACT PROBLEM

  • phuck_Sony Apr 07, 2008

    Seems to be a manufacturer issue. I have had my tv for 14 months. I tried to get the company to stand behind it as we probably have about 600 hours on the lamp, but they said the warranty expired. Have had old tv's thta cost 10% of this one that lasted for 15 years. Truly a disappointment. If any one else has had any luck with warranty or pushing the irght buttons, I would be interested in what they did.

    I also have a Sony KDF-46E2000,



    (Also purchased in Nov 2006)



    I assumed this was a power supply issue, based on the sound and picture cutting out. I didn't suspect the lamp since the brightness was fine on the TV until this happen.



    I cannot believe the limited life... I guess we may have a maximum of 2000hrs on the blub.... not 8000! I wonder does this mean replacing bulbs every year and a half????

  • tonynova May 14, 2008

    I bought my Sony KDF-46E2000 in December 2006 and here it is May 2008 and I am having the same exact problem. About a month ago I started getting a message on the screen when I would turn the tv on saying "projection lamp nearing end of life, please replace lamp soon", and now, the tv just shuts off and starts back up again the same exact way your's does, but I'm not getting the indicator light on the front of the tv for the lamp to come on. I called Sony to see if it is in fact the lamp or another problem and they told me that it is probably the lamp since I'm getting that message on start up. Since a new lamp costs $200 I have to wait a while before I can buy a new one, until then, back to the old analog tv.

    I have the same problem. I bought a kdf46e2000 in feb 2007, and stays on for like 5 minutes thens shuts off. the green light blinks then after another 5 minutes the image comes back again. I called Sony they gave me the phone number of an authorized service and parts dealer. When I called them they told me just to tell me what is wrong with it is 65 dollars. Sony really sucks I will not buy any Sony product.

  • Knosound Jul 06, 2008

    I bought my KDF-46E2000 in November 06 from Crutchfield. I started experiencing this issue yesterday. It's a good thing I go the 5 year in home warranty from Crutchfield or else I would have thrown this POS off of my balcony. Anyways....I have the same symptoms as everyone else here and I'm hoping that it's just the lamp which only takes a minute to swap out. A tech is supposed to call me tomorrow to set up and appointment to come out and look at it. Prior to that I'm going to ask him to bring an extra lamp (Sony XL-2400)!

    I will update everyone once I know something definite. Until then....I have a 27" in storage...hey it beats nothing.


  • yankee301 Jul 11, 2008

    Same problem, same runaround from Sony. The KDF-46E2000 will not last two years. Is there a way to make our complaints heard at Sony other than by talking to some customer service rep.

    Same problem. I am going to try take the bulb out and clean the dust. Keeping my fingers crossed, because there is no way since July '06 that we put 8,000 hrs on that tv! If the cleaning works I will post asap.

    Does anyone know if it is hard to replace just the bulb (not the bulb + housing)?


  • Anonymous Aug 28, 2008

    Had the same problem. The tech had to replace both the ballast and the bulb. Seems to have fixed the problem. Let's see if it lasts.

  • Anonymous Nov 17, 2008

    I have the kdf 46e2000 purchased in November 2006. I am getting the on screen message that says lamp is nearing end of life and to replace. I thought I was smart when I took out the certificate of coverage for repairs. I was upset when their customer service dept told me that lamps are not a covered item. I don't like the idea of spending $200 for lamp replacements every two years. If anybody decides to sue, let me know

  • Anonymous Dec 18, 2008

    Yeah. It was working fine yesterday. When all of a sudden today, I tried to turn it on. The blue light on the far left side started blinking and the other two red lights were blinking in concert with it. Until finally the blue light cut off and just the red light under "lamp" stayed on. I guess that's what the problem is. So I called the rent-a-center from where I am renting they're coming tomorrow. Who knows...

  • Anonymous Mar 05, 2009

    i called sony w same problem w less then 2 years , i called asked for a manager got them to reimburse me 50% form the lamp

  • mattsrocky May 03, 2009

    I have the same problem as everyone else. And that is that I bought a sony and got shafted on a nice TV.


    One person said that the bulb only last 2000 hours and if sony told you that none would buy there TV.


    Well in my opinion that is false advertisement. And I feel that maybe a class action suit should be placed against them. It sounds stupid to have to go that route, but when is enough? I have read pages and pages about how many people are pissed about this same problem.


    I will not spend $300 for a new bulb when 2 years or less it will go bad again. Might as well buy a Panasonic.

Ok, the solution for all our problems is in fact the lamp. I finally replaced my lamp and no problems to report. Sony should do something about this because I know I didn't have 8,000 hours on the lamp and it sounds like no one else has either. I tell you what, I'm NEVER buying another Sony product ever again. Not only did I have this problem but I bought a Sony Blu-Ray disc dvd player and I've had nothing but problems out of it. I keep getting firmware updates for it but it doesn't help and recently I bought a Sony Walkman MP3 player and for no reason it quit working, it would power up and immediately power off. Sony did replace it though (but of course it was only $70 compared to the prices of the tv and dvd player).
Anyway, if you are still having problems with your tv, the lamp door is on the right side, pop it open and there will be another door with a knob on it. Turn that knob counter clockwise to unlock it and pull it out. Inside that door you will see the handle for the lamp, put your finger through the loop and pull up and out at the same time, to put in the new lamp, push lamp straight in until it won't go in any further and puch down, it should then be locked in place. Replace both inner door and outer door and you are good to go.
Someone mentioned something about cleaning the dust from around the lamp. I tried that before I got my new lamp. It only worked for a day and gave out again. Hope this helps.

I would try opening the lamp door and taking the lamp out, and get all the dust out of the compartment. I had the same problem as everyone else here, so I ordered a new lamp. Upon getting the new lamp I went to replace it and noticed quite a bit of dust in the compartment. I removed the lamp and cleaned the dust out, and re-inserted the original lamp, and it works great with no further message on replacing the lamp on start-up. Now I have a spare lamp and the old one still works. Im not saying it will be a fix all for everyone else here, but it is sure worth a try as it is kind of pricey for a new lamp.

I have a Sony KDF-50e2010 which is 18 months old, it worked fine until I went on Holiday in August, when we got back the first turn on it ran for a few hours then the screen started going black or partial pictures with loud static noise. Turning it off and leaving it for a while seemed to solve the problem, but it happened again a day later, and on and off for the next week, until it got to the point it would be on for just half an hour and then go off.

After reading up on the tv, I decided the lamp must be on the way out and managed to purchase a new one for £150. Fitted that and it had no effect what so ever. Half an hour viewing then it cut out. I read up some more and decided the fans must be dirty so it wasn't keeping cool enough. Took the set apart (I do coffee machine repairs and so I am technically competent) getting at the blower that cools the lamp is not for the faint hearted as you have to remove quite a few connectors and boards to get it out. Cleaned the fan, put it all back together and.....It worked for 3/4 of an hour before cutting out. Decided the fan must be dead completely, so set about ordering a replacement (not easy to find) in the mean time I positioned a 12" desk fan next to the door where you put the lamp in, with the outer door removed (the inner door closed of course) and with that blowing into the lamp entry point the tv will run fine as long as I want!

Got a new blower, fitted it in the tv, but only get a couple of hours use before it cuts out again - back to the desk fan! I suspect now the problem is the Ballast overheating as the air is channeld past that to the internal blower - the Ballast most likely needs replacing when I can find the right one - in the mean time I have got rid of the desk fan by buying a USB cooling fan for a laptop pcmia card and modifying that so it blows into the vent above the lamp internal door - this seems to provide enough air flow to keep the Ballast happy.

So my 18 month old Sony Bravia is powered by Wind!

The lamp has about 3000 hours of life (2 to 3 years under nomal use) . they are a presurized gas bulb that weakens over time. as it weakens it requires more power until the power supply (balast) can nolonger light the lamp. the part number is F-9308-750-0 $199.00.

I also have a Sony KDF 46E2000 that my husband purchased back in November 2006. It's now June, 2010 and for the past two years when I turn the television set on, at the botton left of the screen a box would pop up stating "Projection lamp life is ending, please replace bulb." (or something to that effect). I let it go because I didn't want to have to spend the $150- to buy a new lamp. Well, this morning it finally stopped working. So just as a little information, if you see this box pop up, you don't need to replace it right away. Like I said it was saying that for two years before it did anything. I love this television and it's the only issue we have had with it. I like the fact that the bulb is very easy to replace. Maybe we got lucky and got one of the better tv's since it has lasted us almost four years before having to replace the bulb?

    I have had this TV since 2006 too and I started getting that pop up. All you have to do is go into settings and tell the TV that you replaced the bulb and it wont pop up again. Since then I have been running the TV non-stop for about a year and a half and finally in Jan of 2011 it is truly failing. My wife and I love this TV and have decided not to upgrade anytime soon. We're going to the store today to get a new bulb and hopefully get another 5 years of enjoyment out of it.

  • Chesty P Jan 29, 2011

    We bought this TV in 2006 also and went for 3 years with no problems. Then we started to get the pop up too. I went into settings and told it that I had replaced the bulb. After that, no problems. That was almost 2 years ago and the lamp has finally failed. We love this TV. and hope to get another 5 years of enjoyment from it. Let me add that the 5 year we have had this TV has been constant TV. I have 3 little kids and my wife is a stay at home mom. SO the TV is always on and I play video games late at night. "Great TV!"

Yeah it was the bulb for me. I didn't buy the housing just the bulb and it worked great. The thing that really bugged me is the TV never gave any warning about replacing the bulb. And oh, btw, the lamp does not have continuity through it so you cannot check the bulb using a multimeter.

Update: I had the repairman arrive on 7/15/08 but I called him ahead of time and told him to bring the exact replacement lamp (Sony XL-2400) just to save time in case that was the issue. Well to my surprise he swapped out the old for the new one and bingo we are back in business. He stated that the bulbs do not last as long as Sony states, and that if they advertised that the lamps only technically last 2000 hours, that they wouldn't sell too many TV's!! ..haha makes perfect sense to me, even though it sucks.

To this day the Sony 46E2000 never looked better. The picture is incredible once again. In my opinion doing anything else to your TV other than replacing the bulb, is only a temporary fix.

Cheers

I TOO am experiencing this same exact problem... and i purchased my TV in November 2006!!! 14 months, at no more than 3 hours per night... that's only about 1300 hours, when Sony says it should last 8000 hours. I love my TV, but this is terrible!!! I already purchased a new bulb on ebay, so I hope the directions on how to replace it are good.

I have - of course - the same problem.

I have had the TV for 14 moths - at 10 hours of use a day (and that is probably double my actual usage) it should only be around 4000 hours - half the life.

I called Sony and that was when the Rep told me the one piece of info that was shocking - that everytime you turn on the TV, you use 10 hours of lamp time.

So with that in mind, if you turn it on once a day for a year you've used just about half of the life of the lamp - and that is not even watching 1 minute of TV!!!!!

That said - I am going to escalate this issue beyond thier customer service dept, and am looking to have the TV replaced with a new model BECAUSE Sony has stated the lamp lasts 8000 hours, but nowhere does its state anything about the 10 hour burn for turning it on.

I would NEVER - NEVER have purchased this TV if that information was available.

I was mislead, and plan on being fairly compensated for this.

I suggest you all call Sony and lodge the same complaint. There is no way a customer should be expected to shell out 299.99 for a lamp every year just to be able to watch TV.

Well I got this Sony kdf-46e2000 Nov 1/06 as a replacement to the first tv I purchased (faulty within 7 months) - no warning, no pop up screen indicating bulb issue...tried turning tv on and power light flashes, then red led under 'lamps' comes on. Buy a bulb at 240 and hope thats the problem as they are not returnable! This tv sucks. If I had seen these comments prior I wouldn't have taken this one. Shame on Sony for advertising long life when looks like your lucky to get 2000 hrs! But as one other comment above, I've had mine just about 4 yrs.......

Well heck, same thing with me. Would be watching the TV (kf-50e200a), and after half an hour, the power led on the front of the TV would flash three times and continue to do so. Anyways, refered to the manual and it mentioned that the bulb housing was not inserted properly. Considering that I had never removed the unit,something was up. I proceeded to remove the access cover, then the lock plate, found the unit and removed it. Wow, what a lot of dust I found in there. I got my can of compressed air and proceeded to blow OUT the dust from inside including the rear cooling fan. After all this I put everything back and turned the TV on from the remote, same red light flashing. I then removed all the covers again and reseated the bulb housing until it was in there well. Also ensured the lock plate was actually locked in place and finally put the service cover back on. PRESTO, no red light. TV has been on for 1/2 an hour now and no problems. Still cant figure out why the bulb housing came loose. The only thing I can think of is that I have a self powered bass speaker behind the TV. Is it possible that the bass loosened up the bulb housing and thereby triggering the sensor?? I will see in the next few weeks if this is the problem. Bought the TV back in December 07, and already had that optical block replaced, under warranty of course.

I've had this T.V. for about 16 months. The first time I had a problem the top of the screen turned purple. The technician came out and replaced the bulb and it was under warranty. The second problem was the T.V. shutting it's self off every 30 minutes followed by a flashing red light. The technician came out and replaced the power switch and it worked just fine for about 6 months. I was just out of warranty. After 6 months the same problem with the T.V. shutting it's self off followed by the flashing red light is re-accuring. I guess try replacing the switch for a temporary fix for this issue. I want my money back.

I am now having the same problem on my 20 mos. old Sony KDF-46E2000. Sony was not helpful at all. I told them that I will never again buy another Sony product and I will make sure to spread information about the poor quality of Sony to anyone who will listen. My screen shuts off, the power button blinks 43 times (42 times then once more but quicker) and then the tv comes back on for less than a minute. After that the whole cycle repeats itself. I really hate to buy a $200 bulb but I see no other way around it. What happened to tvs lasting at least 10 years. My parents have a tv (obviously technologically different) that is 35 years old.

Same problem here. Purchased this POS May 2007 and now it is July 2008 with maybe 1000 hours on it. I am calling Sony today and explain how happy I am with their product. I have taken the TV down from our Chase yet. Where is the lamp door located.

SOURCE: Sony KDF-46E2000 - Screen Goes Blank

You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance:
1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours
2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris.
3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle

Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!

KDF-46E2000 turns off then back on by its self


* Most common would be a couple of capacitors in the power supply that are not letting the proper voltage to the lamp.
* The lamp itself is not working properly.

No picture or sound


3 times error shows that lamp is not installed properly or lamp cover is off / not fixed.

If you replaced TV lamp recently then check lamp cover and make sure to seat it properly.
Need further info, let me know.

The lamp can cause the picture to cycle without spitting out a lamp error. I'd replace the lamp and clean out the dust/dirt from fans, etc to hopefully resolve your issues.

You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance:
1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours
2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris.
3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle

Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!

MY Sony (same model) has OUTstanding picture resolution and quality., I never have blockiness on any of the sports channels. I would say, give Comcast a call and complain about their signal.. they have a tech come over for free diagnostics on your wiring..
