Loss of Sound and picture on my 50 Inch Magnavox Plasma

I have the same problem tv won't come on you hear a couple of clicking sounds and then the green light tuns into red blinking light that blink 4 times and then continues to blink that pattern. I hooked my tv to it's own surge protector and repeatedly switch the tv on and off with that and eventually get tv to come on. I am leaving my tv on all the time and that is my solution for now. I have a good bit of electronic experience and I get no solutions from magnavox and don't have faith in my local tv repair man as this is more of a computer monitor than a tv.
Does anybody know what part is going bad in all these tv sets and can you order it.

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If you're under warranty, this will cost you nothing. If you're not under warranty the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher. You should call the manufacturer for your full range of options.

Your problem is caused by a power supply issue it sounds like a capacitor is leaking or has vented and will need to be replaced if your comfortable you could check the power board for a can shaped electroletic cap that has vented it will be puffed up on the top the value is printed on the side you can or have someone replace it that should take care of your problem the power board is the one where the AC cord plugs to or leads to

Dear readers,

I found a bunch of videos on youtube for repairing the magnavox plasma. Here they are:

On the third link I actually found the exact part number for the capacitors. You can order them here like he did:

Tv keeps turning on and off


You probably have blown capacitors on the PSB-power supply board. Recaping with new UF caps works 90% of the time. The set turns itself of into a fault protection to keep from damaging more components internally. A few bucks a soldering iron some solder should do the trick.

Have 50 inch samsung plasma tv.have sound but no picture.


If the sound is still going and you can change the channels then the problem is most certainly the ysus or zsus board.

42 inch LG Plasma TV - Lost picture


This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.
