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

My TV was working normal for it's 3 years. I turned it on one morning and all I get now is a BLACK screen with SOUND. What I can I do to repair? I appreciate all help. Stay Bless 3yr. old Magnavox 15in LCD

I have a Magnavox 20" 20mf605t/17 LCD TV. The color on the picture appears to be faded or fuzzy causing a poor picture. It does not matter if you are using the TV or playing a game. The people in the picture are sharp its just they appear to have a haze on the them.

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
