Re: Problem with TV screen?
Good Day, deon453; Sounds like a convergence problem. Corrective Action:Replace the defective Convergence Output IC Part Number 23905094 (STK392-110) using the revised “T” version IC Part Number 23135090 (STK392-110T). When Convergence Output failure is detected, it’s recommended that both IC’s be changed to the “T” type IC version. Good Luck, Big Irish.

Hey! its me again. I think what your experiencing is called overscan. This website might help but if not just google how to fix overscan on a projection tv.
You have two possibilities; either buy the original remote or look up the code for 'universal' remote for that set here:
If you can't find the code set for the remote & TV you have, look for a code set for one of the following brand names:
Funai, Symphonic, Sylvania, Emerson, Aventura, Durabrand,
ESA, Magnavox, INSIGNIA, Philipsand Misakai
there it is a complicated problem your tv seem to have one big problem with the supply module inside him the power current was accidentaly increased and now your tv dont respond better and your picture is enlarged because had a big alimentation current and now you must to go in authorized service to fix that problem
The warped, too large picture is the same problem, the TV has a convergence problem. ln today's electronics the first thing that should be done on any electronic device is to, reset, unplug TV from the a/c outlet for at least 4-5 minutes then plug back in. If no fix; Your TV has a circuit problem. RCA has three common problems that could cause this condition; the most common is a fuse near the fly-back, IH-VT, the convergence power board or the signal board.
Always, call a factory authorized service dealer if you are not familiar with repairing electronic equipment that contain HIGH VOLTAGE, just for your own safety.
I replaced the screen on my 62 inch projection TV for about $50 and the the picture quality is good! Have a sheet of plexiglass cut to the EXACT size needed. BEFORE installation it MUST be frosted on both sides by either a fine particle sandblaster or by sanding it VERTICALLY on BOTH sides with a power sander and a fine grade paper.
If this is only an OUTER protective screen and the image is projected on the inner screen then DO NOT frost the replacement screen, just install it.
I replaced the screen on my 62 inch big screen for about $50 and the picture is very good! You simply need to purchase a piece of plexiglass from a glass shop or hardware store and have it cut to the EXACT dimensions you require for your TV. NEXT the plexiglass must be FROSTED. This can be done by a fine particle sandblaster or power sander with a fine grade paper. I used a power sander and sanded BOTH sides methodically and vertically on BOTH sides. I recommend buying a couple of 12 inch wide strips to test which method pleases you most by placing them in the path of the projected image where the old screen was removed. In any event, I recommend frosting BOTH sides.
The fresnel screen itself would cost about $300 if that is damaged. If it is an additional screen covering it, then I would expect it to cost about half that price. I'm not sure however if it can be easily removed. Sometimes it's a friction fit, other times it can be a real chore. You may want to contact a local repair shop to do it.
