http://www.shopjimmy.com/catalogsearch/result/?q=42SL80
The power will deliver 5V in standby and when it's powered on the "main" will supply a 3V to turn on the run sources (12V and 24V). If you have audio and you can turn it on and off and change channels then the "main" is likely good. The 24V also goes to light up the back lights with the inverters. So if the panel lights up slightly then this circuit is working then the problem could be the T-Con. this circuit takes the video signal from the "main" and supplies it to the LCD display. If you have a bad back light and every thing else is working then in a dark room pointing a very bright flashlight into the screen you will see the video is present.
