This sounds like a mainboard problem. Unless you do not see a back light flash when you turn on the TV, which may mean it is an inverter board problem, this is most likely fixable by replacing the mainboard.

Fixed it, at least temporarily I had the side off my trv250 examining it, especially the CCD connection. I had read the post about soldering a capacitor to pins 1 and 3 (from the left) on the bottom row. I didn't have the specific capacitor on hand, but I started touching some of the small ones I did have to those pins. I found that after I touched a 100uF, 10V cap to pins 1 and 3 the picture suddenly came back to life and stayed that way after removing the cap. I have no idea how long this will last, and I've set up the cam on a tripod in the livingroom with the LCD display facing me so I can monitor it. If you, like me, figure you have nothing else to lose, you might want to give this a try. Note: my camera was suffering from the green smeary horizontal lines problem, and wasn't completely black. I'm not sure if this makes a difference or not.

Easy way to Diagnose is get a known good CCFL from a laptop or LCD TV and start plugging it in to the existing Cathode's Ports one at a time. Generally its a bad CCFL on these multiple units.. (2,4,6) Bulbs.. Moniserv.com for replacements.
