LCD TV?
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

I hooked up my wii on av1 with a component cable with audio on audio 1 and i have sound but no picture.


If I am reading this right, you are only hooking up one cable for audio. There is another cable needed for video. This jack is normally color coded yellow and labeled video out/in. You can use your audio cable to try this and then you will picture but no audio.

AUDIO NO PICTURE


No picture is your problem? No model number but a suggestion if a LCD set---in a very dark room look at the screen with a flashlight--see a faint image of any sort there?

If you have audio and no picture it is the scaler chip burning out you need to stop the heat build up.

The DVI input on this set is meant for picture only.. ex. to display computer picture.

There audio but no picture


I don't know how you connect the unit to the tv.
Let's just start on basic:
composite video/audio(yellow-video, white/red-audio) connect to TV composite video/audio input behind the TV.
If the audio works but no picture,try to use another video input behind the tv.if that still doesn't work,use a different video cable!
Good luck!
