Magnavox Rear Projection 51MP392H/17 has ghosting issue double hallow. TV is six (6) years old. any idea what's wrong?

If this happened suddenly and the red and green images are bowed in at the center of the top, bottom and both sides, one of the convergence amplifier IC's has failed. The part number is STK392-120. Make sure it is a genuine Sanyo brand replacement; there are a number of cheap imitations out there that do not last. Generally they cost less than $30 each.

Note: there are two of these in each TV. They are notorious for having a high failure rate, so I usually replace both. (FYI: each chip has three amplifiers. Each color gets two amplifiers, so one color uses an amplifier on each chip. That's why we usually see at least two colors go out of whack when this problem happens.)

I assume you have already tried a different video source (DVD, VCR, etc.) to rule out input signal defects. If the problem arose right after the set was moved, either the optical alignment was disturbed or (less likely) there is a stray magnetic field near the set that is causing problems (magnetron from a microwave oven?). There is a procedure (sometimes provided in the owner's manual) for adjusting convergence using the remote control that can fix minor alignment problems. If you want to gamble it is not a hardware failure, try it first along one edge of the picture.

If you cannot shift the red or green dots in the convergence pattern, stop immediately, and make a note of where and in what direction you tried to move the dots. Inability to converge the dots is a strong indication the convergence amplifiers are bad (that is their job - to keep the colors lined up with each other). You will need to undo any adjustment attempts after you replace the convergence chips and any fuses or resistors that got burned when they went out, so don't make too much extra work for yourself or your service tech.
