The lights indicate what the issue is. Kind of like your check engine light in your car tells you something is wrong with the engine.

SOURCE: LG Plasma 42pc3d turns on, pops, then turns off

The first thing you should look into is the Z-SUS board, the one situated on the right side viewed from the rear. This board develops a high voltage during operation that might be the source of the popping sound. It is also responsible in refreshing the panel for proper picture display. The weird colors on your TV indicates a faulty Z-SUS board.
Note: Unplug the TV and wait for at least five minutes in order to allow the voltages to drain before you disconnect or reconnect any connector.

  • Disconnect the Z-SUS board from the Y-SUS board. The Z-SUS board is situated on the right side viewed from the rear of the TV while the Y-SUS is on the left.
  • Plug the TV back and turn it on.
  • You will still be able to see the weird colors the moment the TV shut off but do not flash. If it does not pop and stays on and there's a sound, you are pretty sure the Z-SUS board is faulty. Replace it.
  • If it still pops and shuts off, disconnect the Y-SUS board from the power supply. The Y-SUS board also develops a high voltage during operation. The power supply is the one right between the Z and Y-SUS boards.
  • Re-apply AC power then turn the TV on.
  • You'll not be able to see any color or video. If it does not pop and stays on with sound, you have a faulty Y-SUS board, replace it.
  • If it still pops and shuts off, please let me know.
Feel free to update me of the result and your own findings.

Y Sustainer problem. However, normally they have to change both Y Sus and Z Sus boards at the same time. If you lucky than it's just a fuse on the Y sustainer blown (the chance is very rare) otherwise the IPM (Intelligence Power Module) on the Y/X sustainer board is short. more then likely if you can get the IPM off of the board you will see that the components are shot, that is the popping noise you heard. shopjimmy.com has these boards some are cheap some are not...good luck

While watching my toshiba cinema series 36'' television yesterday the screen faded out and made a popping noise for a couple seconds. The picture came back but I have no sound now. Any idea what system...


I'm going to speculate. Audio system component shorted (output), changed bias and picture faded, *POP* component failed completely, bias returned to normal, picture returned.

?Shorted resistors and/or chips in audio output circuits?

I wouldnt expect electrolytic caps to be a problem in these newer units, but you might check for open caps too.

Check your level from the power block, if you can scope your B+, check the ripple. If its bad, the PS block may have been damaged.

Take this with a grain of salt. I'm not real framiliar with these units.

Double check you power cord and try switching plugs.

sounds like its not getting enough power or a CCFL is going or is out and you need to get it serviced if thats the case.


Do not attempt to repair this your self Monitors usally have there own power supply built ind can store massive amounts of energy and will cause serious injury or death.

EchoKaos may not have resoldered his PS board, which most units in that line need. This will most likely solve the problem. A virtually complete resolder is needed on that board, not just the obviously problem areas.

If not -

If the hor lines are upward and curved slightly and a couple of inches apart, then the blue Screen trimpot on the focus block is most likely turned up too high. When turned down the lines will disappear.

This mucks with your grayscale, but then it's trashed anyway by now, and after reducing it, you will have to do a new grayscale on your set, or have one done by ISF. Or a tech who knows how to set the Screen controls, since ISF does not teach that.
