Sony KDF-46E2000 - Screen Goes Blank

Hi This is most likely the inverter panel that drive the CCFL's (Backlight tubes) or the backlight tubes themselves, I'm afraid I can't help with the diagnostic test or service menu.

hope this helps

Hi,
It is problem of weak lamp that has been reached to end of its working hours life, replace lamp in tv to fix tv problem.
Lamp replacement procedure is easy and would be written in user manual.
Thanks.

I have the same problem I was told that the new bulb that I put in might be faulty.

If lamp has not been replaced in last 2-3 years, get it replaced now because existing lamp is dying and causing problem.
Lamp replacement procedure is easy and written in user manual of your Sony KDF-E60A20 tv.
Thanks.

I am having the same problem with my Sony. I bought it at Circuit City in November 2007 and the extended warranty, which I thought was for 4 years, has expired. Has anyone else had this problem, and how did you resolve it?

This problem is caused by a defect in the optical block. It causes about 1 - 1.5" tint usually green, orange, or yellow at the top of the screen. The part is very expensive, retails around $600-800 usually. You cannot fix it without replacing the optical block. They did have an extended warranties for this particular issue because of a class action lawsuit on certain models. Call Sony to see if your model is one of the ones they extended the warranties.

I think TV on for minute or so, goes to standby and again power up, show picture for minute and again standby.
If above are symptoms then its time to replace lamp in TV.

Let me know if symptoms are different.

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.

4 flashes is a bad fan, 3 flashes is lamp door switch

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.
