Answers :


The board you are talking about is called Z-sus. Its role is to sustain power to the plasma panel. If the Z-sus board fuses keep blowing, then the board is usually shorted, and the repair is done replacing the board.
In some case a defective PSU can cause the Z-Sus fuses blowing.
When the Z board is failing, the Y board must also be tested.
The Z board should be the same as this one. Check model and test the part before purchasing.


\015\012This is the X-systain board replace this board and your problem will be solved. The part number can be found on a white sticker some where on the board. Get the number and google it or enter it on E-Bay because alot of shops sell these boards when the get units with bad screens. Or try www.shopjimmy.com for a new board.

I have a Sylvania 6420FF 20" color TV that will not turn on. I can hear a slight buzzing when it is plugged in if I put my ear to the side of the unit, so it is getting power. When I push the front panel power button - it will not turn on. It is 5 years old and has been in our condo and used very little. Is there a fuse that can be replaced? Other thoughts? Much appreciated.

This is about the PN50A450. Last night the television started making a loud buzzing noise, the picture turned into red fuzz as well. I turned the television off (buzzing stopped) and back on, with the buzzing returning but without any picture now. It is not obstructing the sound coming from the surround sound speakers, but instead coming from the TV itself. In fact, the buzzing stops when the TV makes its start up noise and then starts again. The TV has been unplugged in every way but the proble

Vizio GV47L...when i turn on the tv, the screen stays black. The vizio light turns white and it makes the click noise like normal but after a minute of it doing nothing the light turns back to amber.

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

Buzzing noise Just recently, my Canon 40D w/ 300 2.8 IS began making a buzzing noise when I press the shutter button. It will do it for a while, then act normally. I tried turning off IS, and using manual focus, but it still make that buzzing noise. The photos are coming out fine. Just concerned that it might be something serious.

I wonder if you can give some advice. Please. I have a Samsung DLP HLT5076S that is 3 1/2 years old. I replaced the lamp in November 2010 from a bulb site on line because I had no picture and three flashing lights. After reading several forums this seemed the solution. After that seemed to work well. However, shortly thereafter I began to hear a very slight buzzing noise. So I researched that and most things pointed to color wheel. I didn't hear the high pitch whining though just a slight buzz.

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both - either can cause transformer buzz and / or inability to power up.Any caps in these sections (or any other section for t ... Flat Panel Televisions

Why does my Panasonic 52 inch rear projection TV make a clicking noise with no picture after turning on the power? I replaced the lamp a year ago with no issues.

You might want to look at the lamp again to see it is intact and not shattered----2,000 hours or 2 years is normal life for a OEM lamp but a generic or cheaper version lasts about a year and picture is usually not as bright as with the original ones. ... Panasonic PT-52LCX66 Projection Television
