The other day I was watching a movie on my television,then suddenly the t.v shut off, and then it came back on all by its self. The picture on the screen now appears to show the red color distorted and it is not matching up with the other colors. All the other colors are fine at the moment except the red. Please get back to me a.s.a.p, so that we can get a price evaluation on how much it would cost to get our television fixed. We have a Samsung Model # HCM 553 W, "55" Thanks Jon
There are two big Audio Amplifier Chips on the conversion board The first three solder connections on each of those chips commonly are burned and lose connection. You may just need to resolder the connections. These Audio Amps are running extremely hard and it is not uncommon for them to overheat and char the connections, or burn up the chip. But the cheapest fix is to resolder the joints first.

Ur convergence is dying or well be dead.3D pics or shutdown.U must know how to solders? The parts in convergence board must change like ICS,and all it resistors.The websites Tv Repair World.com,Tvrepairkits.com for the convergence kit.The shop will cost u $300 for parts and labors.
You have a vertical sweep circuit problem. There is an IC chip that controls this which may have failed or the capacitor for the IC has failed or both. The third possibility is that a fuse on the power board that supplies voltage to the convergence ICs has blown.The first step would be to check voltages to the convergence ICs. If that is okay then the vertical sweep circuit would be next, These are simple repairs but require some tedious soldering and familiarity with electronics.
the arcing sound is some kind of high voltage leak, which will shut down the tv. pull the speaker grill off and the access board, look at the 3 picture tubes, turn the set on you will see where the leak is, it's usually the high voltage splitter, which has a high voltage wire going into it and 3 high voltage wires coming out going to the picture tubes, if it arcs from the splitter you need to change it, if it arcs from one of the picture tube wires you need to pull the tube out and fix the high voltage leak, and possibly a cooling fluid leak caused it, not an easy reapir, you probably need a repairman.
power in the tv has nothing related with the DVD. The tv has to have raster (white screen) even without signal (cable, DVD, others) if the tv alone is just having the led flashing and neither sound nor video (black screen) The tv has a short circuit in some of the boards that are part of the tv system. the blinking is part of a protection when the tv was created in the factory. Refer to the technician to repair this problem.
Thats what happened your convergence went out, those parts can be found online for as little as 12.50 a piece. If you are good with solder its an easy fix. I found a guy on craigslist in denver who fixed it for 150 good luck
Sorry, but there is not much you can do at this point. Could be a number of things. Convergance chips shorted, power supply bad. Horizontal circuit shorted. T.V's sence a problem and shut off. They hardly ever blow a fuse anymore. Problem is Magnavox sets are very poorly built and have a ton of different problems. Then you have other sets like Toshiba or Sony that only have one specific problem, and chances are that's what is wrong. I usually tell people not to waste their money on fixing Magnavox. We call them Maggot-Box. They used to be good when NAP owned them. They gave techs all kinds of help and service literature....They were great. Now a days...The absolute worst company out there!! MOST repair shops won't touch them. They just don't hold up to repairs.
When resistors and or fuses burn out, it's a sign that some other device was drawing too much current. So, replacing these parts alone will not repair the TV. There could be a couple of things that may have caused this condition. First, look toward the front of the chassis (from back) and look a shiny substance (fluid) on the circuit board. Look very closely! It may be your convergence circuit, most common, IS's. If you are not experienced in repairing TV's, I would call a factory authorized service dealer to have this unit repaired. It will take an expert to repair TV properly.
Sorry I could not give you good news, good luck; Big Irish.
