DIstorted picture for 480p input only

I've seen other postings about distorted pictures, and mine is similar, but it only happens when I'm using 480p input. Whether or not the TV has been on, changing from another input source or a 1080i input source to a 480p input source gives me a distorted picture for about 15-20 minutes.

Thanks for any assistance!

Re: DIstorted picture for 480p input only

Many set have two differant convergance settings one for 480 and one for1080 this is because when it changes mode the set runns a differant frequencys, what may have happened is you have a cold solder joint somewhere that takes this fifteen minutes to corect itself, might want to start by resoldering the convergance and high voltage curcuits

5 year old RCA 50 inch projection tv. Picture went off.

If you are using component cables make sure they are all connected properly( pushed all the way in and in the correct input). I have seen the red cable come loose several times and cause no red color in the picture. When you change the lamp it is easy to pull on one of those cables and cause it to come loose.

DLP Colors Are Off - Picture Is Mostly Blue and Yellow

Sounds like you've lost your red video signal (chroma) somewhere along the line. This tv has a 3 board video path. Analog main pcb --->Digital main pcb --->DMD pcb. The analog has all your inputs on it, except DVI and RGB which go straight into the digital board. The digital scales (upconverts) the signal to HD (1080 or native) and sends it to the DMD or light engine. See which inputs are distorted. If only DVI is clean then you problem is the analog board. If you menu and everything is distorted then suspect the DMD board. If you run component or DVI through the resolutions (480i, 480p, 720p, 1080i) you can get an idea between the digital board and dmd. The menu is generated on the digital board. Somewhere red is getting lost.
