Question about TruTech PLV16320 Television

1 Answer

TV won't turn on

I have seen this problem posted before.  The red light comes on but when the power button is pushed the light goes out and nothing happens.  I am assuming that it is the capacitors on the power supply that are bad.  Someone else mentioned that the bad caps will be bulged out on the top but I am staring at the power supply and all of the caps look fine.  The large 450v 150uF cap has a very slightly rounded top but I don't know if that is normal.  If anyone knows that this is a power supply problem for sure and if the capacitors could still be bad please let me know.  Thanks in advance!

If that large capacitors is defective, the TV should still power up normally but it might produce a humming noise through the speakers.
I would suggest to check very carefully the capacitors on the secondary side of the circuitry, specially the 1000uF that filter the 5vdc line.
Let me know if you require further assistance.

Hello,
the error light sequence that you are seeing is indicating a "backlight error". Most likely you have a bad inverter board -the board that powers up the back-lights behind the display panel. They might be available via ebay if you are a DIYer, or you need to call for sony service.
Good Luck!
