Just check the cost of repairing vs buying. But I would prefer you buy a new TV

Sounds that the Tuner and Video IF section to your TV has the fault. Seek tech support. This is a highly skilled work.

First of all, sorry for the mix up on model the model #. I was viewing a problem regarding LG LCD TVs and found your link. My problem is with an LG 42LGX LCD HDTV. It has worked fine without any issues...


Hi,

welcome to fixya and thank you choosing my service..

OK,that is the most and common problem of all LCD TV...

Usually dim and totally have no back-light is cause of bad inverter board.One of the inverter board is shorted that cause dim light and crackling sounds..

This are the sample images of inverter board.
1_22_2012_1_29_43_am.jpg

to make sure that the problem is on the inverter board kindly try to disconnect/unplug it from your TV and power ON then observe if the crackling sounds remain or not..If the crackling sounds gone replaced the inverter board..Also I need to how many inverter board you have? if 2 or more disconnect it one by one to determine if where is the specific faulty inverter board..

Example:
I disconnect #1 inverter still have crackling sounds..next disconnect #2 inverter and reconnect the #1 inverter until you found the faulty one..Note when you doing this make it sure you power off the TV before you unplug or disconnect inverter board because its high voltage..

I need the picture your TV screen..just send it to chesterpendilton@yahoo.com

Regards.
Chester

This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.
