    My TV has barely visible grainy black/white picture, sound is ok.
    How to get parts for it, can I do it myself?

    Yes, I have the same problem... I called a local tech.. he came to the house... took TV to his shop to check the problem and charged an initial $75 service call, which will be applied to the cost to fix. He claimed it could cost anywhere between $300 and $800. we are waiting to see what the total will be to repair....

    What a business to be in.....

I will tell you what.. Not to be annoying but I have found the parts way cheaper than you can ever imagine. The people who sells them are very professional and honest. Shipping from Ireland to the U.S. only took me 2 days! Definitely not 250.00 nor 400.00 like I've seen them before. It took me a whole year and a half to find the parts but i found them for an equivalent of 150.00 or so. I guess I would sell them for 250.00 as well, if I were trying to make money with you to be honest. Keep looking!

If your screen stays black with no sign of light even when it has been on for a half hour or so, suspect the Y sustain module as the cause. If you can see a faint but very dark picture after a half hour or so, suspect the Z sustain module. In either case the problem usually occurs after hearing a very loud pop. Looking from the back the Z board is the large board on the right connected to the ribbon cables from the plasma display. The Y board is the large board on the left with the big square heat sinks. The Y and Z boards are the most common cause for the symptom you described. The boards may cost about $250 ea. There is a white sticker on the board with the LG part number.
Good luck.

LG Plasma 5 years old has 4cm black line from top to bottom of screen

Just mark where the line is, then dismantle it. You'll find a connector & film at the same spot as the line (bottom of screen) . On this film is SMD resistors, resolder them VERY carefully, as these can go dry joint. Clean connectors

Check your cables and TV input settings.  Can you get to the on screen menu?  Does anything appear on the screen when the tv is on?

30" samsung flat screen powers on but tv screen black. sound is good. Worth repairing?

It depends on what kind of t.v., plasma or LDC. and does the screen appear to light up or do nothing (if you turn off the lights, does it glow black like there is no signal or is there nothing at all?) If it is an LCD and the screen is bad then investing in a new one. A plasma might be worth fixing depending on how much a new one of comparable or better quality would cost. It doesnt sound like there is something wrong with the computer/board in it so that shouldnt need to be replaced.

Plasma tv screen goes black once you turn it on. Only sound

I have a panasonic TH-42PX60U plasma TV. When I watch TV programing I have no problems, or with the DVD input. But if I switch to another input, be it video game (PS2) or vcr the screen sometimes goes black and the red power lcd light next to the power switch flashes. Holding the power button in for a few seconds will shut down the tv. Then I can turn it back on and it may operate normally again for a undetermined period of time, before the screen goes black again. This never happened when new. The tv is about 1 year old. Any ideas on this problem? Thanks Ernie

I have a philips 50pf7321d plasma tv and the screen suddenly split, half picture on each side of screen, and black bar inthe middle.

Black bar caused by a short IC on the ribbon of the plasma panel. Unfortunately it requires a new plasma panel. Cost of a new unit.

If the screen is broken then yes, it will and can make odd noises. Your cost on replacing a plasma screen will go beyond just purchasing a replacement television.
