I have a sony tv model kdf-50e2000,and it has a problem with the picture going blank,the only light that on or flashes is the green (POWER) light. when turning the set on the green light blinks as it...

You tv used lamp XL-2400 or also known as F93087500. It is very common for this bulb to fail and have the exact symptom you are experiencing. I cant count how many times I have seen it.. Replace the lamp with either the exact Sony or an OEM and you will be back in business..
Good Luck!!

Suddenly turned off without warning Sony KDS-50A2000


All you need is to open the back cover of the television and check on for dry soldering at the power stage of the printed circuit board, also check for bulged capacitors, if found replace with same rating of voltages , but if otherwise Ur power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get ur tv power stable,and work again.Or tries websites like, to buy a whole refurbish power supply board for the replacement.

Hope this helout, Good luck....

I would take the Lamp out and see if it is shattered. It is not unusual for them to fail suddenly. If it is shattered, you can contact Sony at 1800-222-SONY and order one.

The picture will go black and the sound will go out. At the same time, the green power inicator will flash. Then the picture and sound will come back on for several seconds and then it will go out again....

My TV had the same problem. I called Sony yesterday and they told me to reset the TV. I did so yesterday, and it seemed to work. Here is the transcript with instructions:
Please turn ON the TV. While holding down the RESET button on the Remote control, press the POWER button on the TV. The TV will turn itself OFF, then back ON again. Release the RESET button.The TV will go thru the initial setup, and should work normal.

No picture

These sets have had, unfortunately, bad picture tubes. The gun welds tend to break loose over time.
