Television and Home Theater

I have a Sony KP51WS500 TV. The picture shows lines across the entire tv. Approximately 5 blue lines from left to right can be seen. Each line is equally spaced apart and are not straight across but sort of curved arch to it. Also I'm not sure if this may help but the picture doesn't appear as black as it used to either.

Thanks for assistance.

I have an older rear projection tv that started to have picture problems. I took it apart and found the mirror cracked. The picture is bending and the color won't line up what could it be???????????

   I just had the convergence IC's replaced on my 2002 Toshiba 50H82 rear projection TV. I personally removed the board and took it to the repair shop. As instructed by the repair technician, I marked every connector and wire and after getting the board back in the TV, I hooked up every connection to it's original place. Then I turned on the TV and there was a humming sound like a tube warming up that grew stronger and louder in pitch for about 5 seconds which ended with a soft POOF sound.
