If it is a LCD TV, and there is a faint picture, it is probably the backlight or inverter board (probably the latter). This is a common problem (especially with PC monitors).
Do an internet search for your model and inverter, you may be able to replace it.
Make SURE you REMOVE the power lead before opening the set !!!!
Thank you ryolkowski!!!! We just tried your solution and MAN it worked like a damn. We were all ready to make a trip to the city to get a new tv, an expense we just didn't need right now. You made our day. I can't thank you enough. jabo

It can be cold solder joint in the power supply or component failure after heating up. You should do this when the screen is black out to help narrow down the problems.
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:

A black line down the middle of the TV can be a few things. You plasma panel might be bad your buffer on that location of the screen might be bad or your logic board might be bad. Teh only way to find out is by replacing the parts , You can get parts at www.interliquidparts.com
