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.

first take off the speakers. you'll see the cable for the speaker. in this slot u can put a screwdriver an pulloff the silver front carefully. then you will see the screws at the top and the buttom. but its better to take off the stand before removing the front. there are 4 screws behind a cover right near the stand. without removing the stand u wont be able to remove the display/electronic
