can i fix my lcd tv?

post #1 of 9
Thread Starter 
ive just been given a 32" LCD TV for free because it doesnt seem to work!

basically whats happening is the tv turns on (to standby) and the red light shows then when you press the power button/ channel buttons to turn it on the light go's green but theres no picture!

The TV in question is a Onn LCD32angel-A

ive had a look on google and from reading up a few things ive found that it might be the 'PSU board' although that seems unlikely to me or another person said the 'tuner board' which i cant even find on the net (could just be the 'main AV board')

the problem is its going to cost like £35+ to get one of these parts and i just dont have the money to buy parts that arnt going to fix the problem! i know little about TV's and was hopeing that someone out there might be able to shed some light on the subject!

i realy want to get this screen working to watch films on (tho ill probably keep gaming on gaming on my current screen 1680x1050 instead of this one 1280x720)

please... help!

cheers

Turn all your lights off, put a flashlight right up against the LCD. Is there picture? If so you may have bad CCFL's or a bad inverter.

I'd open it up and check the caps if they're blown. Electrolytic ones tend to bulge or bleed when they've expired.
