Question about Sony KDF-E42A10 42 in. LCD Television

2 Answers

TV comes on then the screen will go blank while sound remains fine. It sometimes goes blank/black after a few minutes, sometimes it takes an hour. The green power light remains on and steady the whole time.

If the screen goes suddenly dark, and the backlight turns off, then you have a faulty inverter board. The inverter must be tested and eventually replaced.
If instead the screen stays for a while white, with backlight but no picture, then it is usually a bad digital controller board.
Test also the TV with no devices connected, eventually only with a DVD unit, and try unplugging power cord for ten or twenty minutes.

I would pull back resolder tuner and power board also look for any puffed up capacitors near heat sinks 1000uf 16v, if no bad caps then most of the time resoldering corrects problem.

that set is highly rated by users .. it first came out in early 2009 (i think) so you might check to see if any warranty remains ... the display is illuminated by several lamps .. each lamp has its own high voltage inverter .. all the innverters are powered by an output of the low voltage power supply (often 18 volts)... i would suspect a problem with that low voltage power supply.. either a bad capacitor or a thermal issue .. .. ..

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

Comment by Guest, posted on Oct 25, 2008My Aquos has the same problem. I'm not sure how I discovered this, but when I lean the TV forward and hit the power button it will turn on every time. If the screen blacks out and I don't lean it forward when I hit the power button, the screen will just remain blank. It is very weird, but at least repeatable.

- Thank you, Guest. That did it. It definitely seems to be a problem with the TV. Tilting it and hitting the power button helped me get the video back.

Sounds like a bad digital board to me. Not too hard to replace in those models but, you do have to write down a few settings before replacing it. These settings are available in the service menu. Any questions let me know tvtek@msn.com
