A bad smell is a blown capacitor (most likely on the power broad)
Take the back off and look for bulged or leaky capacitor, and swap it out.

Its very likely that you need to have LG perform a sodtware upgrade on your unit. Contact LG and see if your tv is one of the applicable units with software upgrade issues, please let me know if it works. Good Luck.

SOURCE: Plasma TV smell?

i had the same prob and thought it would burn off. It didn't after a month. Read the comments and tried the plug direct into wall socket plus i washed off the tv surface several times. Now no smell. Not sure which action cured the problem but i'm now happy. It was so bad i had to leave a window open and at times i would gag from the smell.

SOURCE: Lg Plasma Display settings keep switching

When you boot up your tv for the first time, you get to choose between home and shop-mode.
In your case, he TV is set to "shop-mode".
Then it will go back to factory settings after 5-10 minutes. (so that customers won't mess up the settings all the time)

So change the settings from shop to home, and your problem is fixed!

The noise you hear must be from its back-light inverter board. The ferrite core in the inverter transformer may make a high whistling noise and will be annoying. Contact any technician. It can be stopped by gluing. But is a skilled work.

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.

Tv turns it self off after only 2-3 seconds and makes crack noise


Since the set is less than 1 year old, it should still be under warranty. Request warranty service.

The noise you are hearing is probably arcing inside the set on the power supply board. Continuing to attempt to turn on the set will only make things worse. Please request warranty service as this is unusual for a TV that new.
