Rca tv picture blurry and arched up at bottom

Make sure that all cables, such as HDMI, VGA, or AV cables, are firmly connected to both the TV and the source device. A cable that is loose or damaged can result in signal problems. Additionally, you might want to consider performing a factory reset

My RCA 52 rear projection TV has the letters getting blurry on top and bottom, Picture is OK but visually losing my eyesight staring at blurry numbers and letters.

Is this a bulb or simple fix ??

It is your convergence IC's going out, they cost about 40 $ for both, if you know someone that can solder, i would have them do it, once you see the new parts it is prity easy to find them on the board in your tv, repair shops usually charge 4 to 5 hundred

Convergence adjustment to projection TVs are given.

Does the picture just get dark or does the picture go out completely? Does it do this with both the cable and the DVD? Is the audio affected?

Conversion problem most likely. Do your conversion controls work both colors in all 4 directions.

This indicates a convergence problem..convergence power supply probally.. however ive seen 2 other cuicits cause this ..

We have a Proscan 50" Projection TV. A T.V. repairman told us it was the HV (Horizontal Vertical) Splitter causing this problem and tried to find the part for us. The part for our TV was too hard to find though and we ended up not having ours fixed. Our T.V. is 8 years old though, and Proscan is discontinued. Maybe you'll have better luck finding an H.V. Splitter for your TV. Of course, you'd need a professional to install it for you. Good luck.

Might be a bad CRT, might be a bad focus block, I would refer you to a Repairman as it will take some experience to repair.
