After reading several forums when my LG 42PC3D died, I went in thinking I had the answer. It would turn on, but then off immediately. The Y-sus board had a blown fuse. I didn't want to risk frying anything else, so I replaced the board rather than just replacing the fuse. When I disconnected the board, it would turn on and stay on. Now, with the new board, it powers up as soon as I plug it in (doesn't actually turn on, just powers up) but won't do anything. The screen is backlit with just

Bought a samsung 42' 4000 series tv, its less than 2 years old & the picture went bad looks worse than a really old tube tv watching an old VHS. contacted samsung-they don't care, referred me to a tv repair place (75$ to look at it) who said it needs a new sustain board, will cost 300.00 anyone else hear of this problem? anyway I can do it myself? where can I get a sustain board? why is samsung alienating their customers?

Samsung PS-42Q96HD Hi My Samsung PS-42Q96HD went dead one day no pic and no sound- so I opened up the back and on the psu I replaced 2 bulging capacitors. Now the tv comes on with sound but with no picture. As far as I can tell there is power going through the X and Y boards and the logic board has 2 green led lights on. Any ideas would be greatly appreciated. Thanks in advance

My Vizio plasma vp422 made a loud pop and went off. Now it won't come back on. U can turn on and the vizio display turns from orange to white but nothing else. Also u can see the little green light in the back is burning. I have removed the back and don't see any visible damage such as blown capacitors. Also I checked the 4 little white fuses and their is continuity running through them. I don't really know where to start looking next. Would it be one of the boards? Is there any way of checking

Hi Cindy Wells, the Sanyo DP19648 LCD TV failed at 2 yrs and 8mth that I bought for my parents.

Hi, I came across one of your posts and had a question.  I have a p50hdtv10a, it  died, now the screen flickers and turns off. I've noticed that the led on the main board's power input shuts off and then a relay on the power supply clicks and the tv shuts off, the ysus board is clicking while all this goes on, the pattern of the flickering and the clicking on the ysus board are dead on. Which board could cause these symptoms?
