Hello, I have a Samsung 50" plasma PN50A550S1FXZC ,The tv comes on and chimes and got audio of some shopping channel , but I have no video .All the voltages are OK on the power supply board Vs 204 Va 57 also have 18v, 5.3v , 12v and 3.3v. I put it in test mode and get different colored screens and test patterns. the logic board has 2 upper LED's that flash at 1 second intervals , there is a lower LED that comes on when the power button is pushed for about 3 seconds and goes out before the tv does it's welcome chime. there is no faint image on the screen in a dark room with a flashlight shining onto the screen. Does this sound like a bad main board? Thanks

Re: samsung plasma no video
If you did the self test then everything is working apart from the mainboard, I would think it's a BGA issue, there are repair services on ebay or just replace it. -
