My 5 year old SAYNO 50in flat screen tv will not turn on.
I was watching it two days ago and it just went black and will not turn on. Is there any easy and cheep way to fix it? I have read that the Y SYS board goes out on most Plasma TVs. Any help
If it won't turn on at all then the power supply would be the first thing to look at. If you can take the set apart and look where the power cord enters the board should be near there. If you see that some of the normally cylindrical shaped capacitors look kind of inflated or even leaky then you can get a replacement board or if you have soldering skills rebuild the one that is there.
