We have a 1996 RCA P46733AT. It has been a great TV. It has recently developed a concave picture. The picture, for a day or two was convex and the whole picture seemed to "wrap" its way around the screen. It then became a large hourglass shape with the sides convexing inward.
Are there any suggestions out their on what this is caused from?
Thank You
Sounds like a convergence problem or could be a pincussion problem or a power supply problem. Not an easy fix for a non tech to attempt. This is a job I am afraid for a trained tech. Good Luck and let us know if you get the set repaired and what they found.
