Check out the Electronics forum. There are lots of posts over there about Magnavox TVs.

I agree, probably in the horz circuit. And yes, they should be repaired. No need to replace an entire circuit board, that a little solder and a hot iron will restore. The horiz ckt is the one with the large transformer(ID#5445)with a large red wire at the top, going to the picture tube(located at the rear of the circuit board). Close to the h-v transf will be the horz output transistor(ID#7560), about the size of a postage stamp, but much thicker, that is clamped to the metal shield. The horizontal driver transformer(ID#5461), located in front of the high voltage transformer. The legs of horz dvr tnsf 5461 is the part that usually gets defective connections. There are 4 legs. It's best to remove the old solder and apply fresh solder. Of course you always examine the circuit trace for any indications of any other bad connections, while you have the bottom of the ckt bd exposed. good luck, pw

My 48" magnavox projection screen Model no. RL8544 Chassis no. PTV385-A001. Im having some problems, and hope you can help. Was working fine, then picture went black, Still have perfect sound, but no pic. Pic came on, then went out while I was watching, If I turn it off, and on again picture will come on for a split second, then go out again. picture looks fine when it comes on tho. Im really hoping you have an answer for me. hopefully its an easy fix. I cant afford a new one. Thanks for your help.
