Black screen I have a Samsung un46d8000 flat screen TV which is about 8 months old. It has so far worked without problems but yesterday when switching on there is just a black screen. Sound from all inputs is fine and it looks like that there are 4 small lights in the back that you can see glowing through the screen. Its still under warranty if I can find the receipt!! If I dont find the receipt any ideas? I did have a peek in the back and there looks to be one big board that drives the Screen.

I have a Maxent MX-58HPT51 model P58H10NJA. I bought it in 2007, have been using it for years. I recently moved houses and brought the tv with me.

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

I have a Sharp LC-19DV12U with a defective D501 labeled 10E241. It is located on the power supply pcb connected across the 120v input to the board. The board does appear to use conventional identifiers (c=capacitor, r=resistor, t=transformer) so I would expect it to be a diode although in fact it looks like a ceramic disc capacitor. Unfortunately, I don't have a tech manual or a parts list. Can anyone help with a part number?
