I have this sony tv. 4 years old. i have been having a very dim picture. i started shopping for a new tv and one of the sales man suggested it needed to be cleaned. he also suggested that i unplug the tv for ten mins. then take canned air and blow the fan out then take the bulb out and blow it off then plug it back in and i should notice a slightly better picture. well i did that and i think he just wanted to sell me a new tv. cuz now i have a tv that take a good 15-20 secs to boot then bout for 3 secs with noise then shut down to the standy by light blinking 4 times. and if course it right before my super bowl party. im a mechanic. im very good with small things. is this something i could repair myself? and what about the cleaning processes? please respond i need help. hiclassmotorlube@aol.com

That is the blink code for the lamp ballast. Here is the more complicated explanation from the service manual.

IC2301(pin11) detects the error of LCD Power C.B.A. and Lamp,
then indicates the error when an inner malfunction of LCD Power
C.B.A. occurs, the Lamp voltage becomes more than 130V or
less than 30V, Lamp current becomes more than 5A, or the Lamp is blown

Hope this helps.

if your TV blinks 10 times. Possible solution should be to check and replace on the G1 board Q1600 and Q1601 if shorted and R1614 and diode D1605 open.

Above is your user manual, below is your service and repair manual. http://www.fixdevice.com/smanuals/tv/sony/kdf60xs955.html

This may very well be a lamp problem, or it may be the "Driver" for the lamp, or indeed the Power Supply to that lamp, unfortunately one must troubleshoot these issues to isolate the actual problem, Please use these manuals, and you should soon be able to isolate and effect a repair.

I have a Sony 50 inch LCD projection TV model KDF - 2000 when I turn on light goes green and blinks 4 times and then it goes to the red light and it blinks and 3 time series


Usually that means the lamp is bad. If the lamp is new, then try re-seating the cage/housing. If its more than 3 years old, then I would buy a new lamp. www.projectorlamps.com

I have a sony kdf 50e-2000 the green light goes on then it goes to thr red blinking lamp light. I have no sound or picture. If I replace the lamp light will I get sound and a picture again?


Hi,
Yes, if you have not replaced the lamp since you purchased this TV.
Lamps usually last about 6000 hours.
I've seen lamps last much longer than 6000Hrs, it all depends on the usage.
Remove the lamp from the TV and do a visual inspection, see if there's a crack on the glass or the bulb.
If the TV is few years old then the Lamp may be bad.

For a new Lamp: 800 638-3328

DO NOT BUY the lamp from ebay

Good luck to you.

I have a 4 year old Sony KDF-E42A10 television - the power/standby light blinks red 5 times, pauses, blinks red 5 times again, etc. I have replaced the lamp previously when the light was blinking red 3...


Hi there,
5 blinks means there is a problem with the video board. It could be as simple as unplugging everything, includding power. Wait 3 minutes then plug power only back in. Or it may be a damaged component that requires replacing.
Hope this helps

Hi,
Question shows tv is Sony KDF-60WF655.
Green light blinks when tv gets prepare to fire up lamp, check internal circuits then show picture on front screen.
Red light blinking shows some kind of internal problem during circuit check and protection got activated upon some failure.
Count the red light blink as you will see 3 second long pause and post it here to diagnose what section of tv got problem.
Did you replaced its lamp in last 2-3 years?
Thanks.

No picture


More info please. I assume you have a new Sony lamp installed? Have you closed the outer door for the lamp? When the set fails to turn on, does the front panel light blink a certain number of times? If so, how many blinks?

The tv turns on but then shuts down. will not stay on, any ideas why?


If its Sony KDF-42WE655 TV then it has self diagnostic feature and if it gets any problem inside, its red light will start blinking in specific numbers to show an error code.
Let me know how many times its red standby light blinking between 3 seconds interval.

4 blinks shows problem either one or all 4 fans are not working AND internal temperature high error.

If you are familiar with TV repair and know basic electronics then unplug TV from AC outlet an take off back cover and check fans are running?

KDF-E60A20 Going on and off by itself..no blinking lights


it works!! First i took off the front panel. Just check your manual for instructions, very easy to do. If you do not have a manual just down load one from google.. The instruction are easy to follow. The screw they have you loosen with a alan wrench is attached to the plastic, so you do not have to worry about dropping it inside the tv. Removing the lamp was simple. once out you will notice on either side are two small mesh screens. One of mine was 80% blocked with dust, the other side was only 30-40% covered. I used a vacuum to remove the blockage, i did not want the dust and dirt to go inside the bulb. i then cleaned all around the lamp. Reinstalled, and we are go to go. The kids are happy and i am happier since my wife not be buying a new TV.
total cost of repair $.00
time required to fix, less than 15 minutes.

Also when my TV was loosing sound and picture and then return. I did turn off my TV, then turned on. I nothiced a red blinking light. Mine flashed 5 times. After some reserch, 5 times is video related, bulb or video board. google red flashing light with the model you have and you will find what all the codes mean.
So if yours is flashing 5 times try the above, it might work for you and it is well worth the time before you call a tech and drops hundreds of dollars.

hope this helps.
