Just today I was watching my television, and the weirdest thing happened. Suddenly, the TV flased a yellow screen a couple of times, and went back to normal. A couple of minutes later, the entire screen accquired a yellow tinge, and has since remained unchanged. It was not the channel I was watching, as all other channels do this. As well, the xbox (which is connected to a different input) as well as the DVD player (yet another input) are all experiencing the same phenomenon. At first I thought one of the CRT's inside the TV had blown, but I tried to do an auto convergence using the TV's menu, and all three colours displayed perfectly during the auto convergence. Does anyone know what happened, and what i can do to solve this? PS, the TV is an RCA DP150. Thank you.
