Problem with TV screen?

The image on my TV's screen lately seems too big for the screen itself. It cuts off some of the image on both sides.

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.

Repaired the convergence and now the image quality is good but the TV seems to be over projecting the screen. The top, bottom and sides of the image are cut off slightly. is there a way to adjust?


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.

Projected image is too large for screen


Good Day Brian;

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.

Good Luck, Big Irish.

Xbox 360 screen cut off on left side


Ok, I've had the same issue and I was able to fix my problem. I was getting cut off sides in HD mode on my playstation.

I entered the service menu by doing this:

Turn TV Off
Use remote and hit "Mute 1 8 2 Power" (not at the same time, but one after the other)

The TV will come on with the service menu. Enter the 1080i adjustment screen. Write down ALL the values in case you mess up. Adjust the values as necessary to fit your screen. It's sort of like adjusting a computer monitor's image for different resolutions.

Screen Problems


Has the TV been dropped lately? If so it's possible the coils that guide the electron beam are misaligned. Also many tv's (same for computer monitors) have either manual knobs or firmware controls that allow you to position your screen and adjust height, width, etcetera..
