No Picture on Magnavox 42" Plasma TV

We were watching TV last night with it made a click sound, just as it does as it turns on and off, however we lost the picture and can not get it back. We have the sound, but no picture at all, not even a blue screen. Does this spell the end of our TV? Is there something that can be can? Thank you

    Thank you, We have also just noticed when we have the television on with the sound it turns itself into stand by mode, is this a part of the same problem?

Plasma displays use a fairly high voltage and the supply for it has failed.
If you want to check on your own, remove the back panel and look for one or two boards with far fewer and larger than average components on it or them.
If two boards are present, the one most obviously related to the incoming AC cord will be the main supply but in some sets, the main and HV supplies may share a board.
Locate the part # and email the manufacturer for a price on repair or replacement.

    It could be and that is pointing more toward the main power supply which, as previously mentioned, could also have the high voltage circuit on the board with it.


    It is possible to derive the high voltage from a source within the main power supply or provide a separate board for the display.


    It saddens me that so many of us have either dumped or 'donated' our old CRT sets that were dusty inside but working well, to place a new, more expensive flat screen set in its place only to see it die in an inexcusably short time.

Our Sony 52" tv HIM I KDF-55E2000 will while we are watching it go black, no picture or sound, the green power light blinks bout 42 times then picture and sound comes back oon for about 3 minutes then it...


It sounds strange that the power light to this model Sony TV blinks "42" times. It should never happen. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box and press "Enter".

These blinks are fault indications,[Error Codes], and from the number of these blinks, you can get an idea about the faulty circuit stage inside the TV; which will make repair easy.

I have a 52" Sony WEGA plasma TV. The picture went out, audio is fine. No TV picture, no dvd, no anything. What is wrong and how much do I need to budget to fix it? I love my Sony plasma!


that is because plasma tvs have a limit on there screen life and if all is done all day for months and months was watching tv ,playing games then you will need a new tv plasmas **** you can get same quality out of a lcd flat panel and three time the screen life or you could spend anthor grand and have the solution replace and maybe the that part of the control board went out and you will spending about half of what you paid for it to fix thats why i have two lcds have not had one problem with them one 32 for my computer and a 42 for me to watch tv ov on play games with and both the same brand and i paid 1200 for both brand new

Magnavox Plasma HDTV Red light


I had a similar problem with my magnavox tv with the blinking light issue. Eventually it just didn't come one anymore. Looking at other forms they said the problem was a bad capacitor number 2074 located on the power supply board. When I opened my tv, I noticed that the capacitor was bulging and burnt up. I bought a new one labeled 2200uf 35v and did some solder to attach the new piece. Put the tv back together and it works like new. No more blinking light. I hope this helps.
