Question about Projection Televisions
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
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?
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 am having the same problem. I replaced the lamp and get three blinking lights. I called a repairman . They repaired a switch activitor. Now I got a red band on top of television, I took lamp out and put it back in. Now I am getting the 3 blinking lights again. No picture, nothing. Paid 140.00 yesterday, and now get to get them back out. Can you not replaced lamp without calling repairman

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?

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.

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 bought my 46E2000 in August 2006. I am having the exact problems mentioned before, maybe the tv has 1000 hours on it. Guess Sony has some real problems with thier bulb life!!!!!!!!
Posted on Oct 18, 2008
I see there is a lot of people with the same problem, we should all sue Sony !!!

It appears that when the area where the lamp overheats...it triggers the problem. What I did was I put a small fan ventilating the area, and so far that has worked out :))

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.

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!
