    Maybe the bad connection is the reason. It usually happens with improper installation or a poor quality cable.

SOURCE: black screen

This denotes a power supply issue. I would venture to say that it is the part of the supply that controls the plasma ignitor if this is a plasma TV or if this is an LCD screen it is called the back-light and inverter circuit. The power supply board would be the chief culprit in this case.

I hope this helps,

Thank you,

Very common issue with Plasma TV's. Unfortunately there's no common fix, or easy fix either. The symptoms you described could be caused by a bad power supply board (not likely), a bad video controller (maybe), or bad X, Y, and/or Z sustain boards (most likely).

If you're handy with a screw driver, you can take the back off the TV and have a look around. Make sure you unplug it from the wall and maybe even wait for an hour or so before opening it up. This will allow it to discharge any stored electricity, though it's not a guaranteed safety net. Work as though anything you touch might shock the sh*t out of you. Because it might.

What you're looking for is signs of a failed component. Capacitors will often bulge on top when they go bad. IC's sometimes will crack, bubble, warp, or burn. Sometimes you can see that a general area of the circuit board appears darker, and often this will be where something has broken down.

Should you see anything that just doesn't look right, and you're pretty sure that it's bad, you can look for that board part number online and sometimes find a really fair price. From there it's all plug and play. A couple screws, a couple wire connectors, a trip to the hospital because you touched a charged cap, and that's it! Voila! Your TV will be up and running again.

SOURCE: 50 " Phillips Plasma tv. Screen is black, blinking red light.

Sounds more like blown/exploding capacitors on the PSB-Power Supply board. No OSD-on screen display a blinking led or chatter/relay clikcing at startup is the tv going into fault protection and bypassing the startup pins. The YSUS-Main controls the pic which is attached to 2 buffer boards the YBU-upper YBL-Lower. They control the upper and lower portion of the OSD and the YSUS controls both of them. Since you're getting No OSD you need to check for blown caps on the PSB first. Unplugging the set resets the error again. So you start all over again.

Whn the sustain boards go out, its usually due to the buffer boards. Since you have already replaced the sustain boards, replacing the buffer boards should do the trick as these are the boards the control the firing up of the gas inside the PDP(Plasma Display Panel).

I have an LG 47LN522-UB LED TV that stopped working after three years and need help diagnosing a problem with it.


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Something else is going on. The T-Con board has no other function than controlling the picture. If there is a separate board for the led drivers, I'd suspect that one. The main board controls the sound.

This sounds like you accidentally hit the input button on your remote. It will either be INPUT or SOURCE on you remote. Turn on your TV and source(cable box) and hit one of those buttons until your picture comes back

No picture


If you look very close at your screen (might need flashlight here), do you see the picture as a black screen? If so, your backlight may have died on the panel. Replacing the inverter board will fix that right up unless the tube (lightbulb) has burnt out instead of the board. Both are replaceable.. Check it out.
