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:

Brake Box Will Not Work


First try a 12 volt "stab in" test light pushed into the blue wire at the brake controller. Red is brake feed from the truck, black is 12 volt power and white is ground. If all is wired correctly, the blue wire should power up when you hit the brakes. Be sure to turn the controller up to highest setting to test it. When you hook the test light up, the connection indication light should come on. Then turn red when you hit the brakes. Also see http://www.etrailer.com/faq-wiring.aspx for more info.

Blue snowy pixel areas on my plasma


some of these panels were mis-calibrated from the factory after not aging long enough. Let the TV run for atleast 2 hours and adjust the Vs and Vscan voltages. When it is blue in the left I have found generally the Vs is about 10 volts too high.
