Hi, i have an LG plasma, model number RT-42PX11.


You need to pull the power supply out and replace the damaged caps on the board. Look for swollen, pushed up tops and leakage around the base of the caps.

You need soldering and basic electronics skills. You also need to pull apart that big tv and pull the power supply board!

You can look on Ebay for pullout boards from people who have broken their screens. It can get you a working board for cheap sometimes!

Good luck and be careful!

Hi i bought LG plasma model no RT-42PX11 2 years


G'Day!

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If you're under warranty, this will cost you nothing. If you're not under warranty the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher.


I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need additional assistance so that I can help you further.

42 inch LG Plasma TV - Lost picture


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.

LG 42PX10 Plasma


I just fixed my plasma with same looking problem. Mine is a 42PX11. Cost me $320.00 in parts from Fishwick Electonics. Replaced three circuit boards, crossed my fingers and turned it on and am happy to report it has been working fine since for about 6 months now.

Hitachi plasma tv went snap and now there is no power


I realized that I bought a piece of junk. It will probably cost me as much to fix it as it did to buy it. Therefore I wont be buying another piece of junk plasma tv. I will buy a product that is warranteed for a reasonable time. My TV was a Hitachi but from what I read from other plasma tv owners, they are all the same. What kind of company sells products that last for a fraction of time in relation to the cost? How can we continue to purchase inferior products for outrageous money? Remember the old TVs, they lasted for years for a fraction of the price!!

Color loss


Hi,

How old is your plasma?

I believe the gas that powers the plasma only has x-hour's life and therfor may need to go for repair in a tv repair shop
