SOURCE: Where can I buy a new power board for my Plasma LG

I had the same problem and opted to take the board out and replace the caps. They were all the same capacitance. Cost me $6.61 for 10 new caps (needed 9, 10 was cheaper). If you can solder, watch the capacitor videos on YouTube and give it a go.
There is a replacement for the original. You can try

Good luck

New to this site! Hope someone has an answer that can help... I have a LG 55 LCD flat screen model 55LD520-UA. Try to turn it on. Bottom light blinks red 3 times blinks blue once, then nothing.

Try to change the capacitors first. Normally lost of lcd tv have problems with the capacitors and which lead to powers problems. May you will not find visually that the capacitor is fault. So go for changing the capacitor also check the following video. Which will help you understand how to check the power supply broad. Also take care while working with the power board there is a risk or electric shock Also one of the capacitor in the power supply holds charge even when you have remove the power supply.

Replace capacitors c520 and c126 to get your power working again.
Also make sure that you don't have a broken green 3 inch jumper wire broke that lies under the heat shield in the top right corner. The wire should be glued to the board for stability. It sometimes breaks loose and will cause the TV screen to stay off.

Good day!!!!

That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Ur power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your Tv power stable,and work again.Or tries websites like, to buy a whole refurbish power supply board for the replacement.

Good luck.....

Hi syzonker
Before you replace the power supply , check for swollen(rounded top)capacitors.
Also check and replace C126 47mfds/50 volts
And C520 1000mfds/16 volts

LG 26LX1D won't turn on.

My LG 26LX1D is the UA Version.

The solution for my problem was unclogging the Small Fan by the Main Panel, on the opposite side of the TV as the Power Board.

This is My Story.

The TV I found at the dump seemed good, but would not turn on.

Two LED's showed up on the front panel of the Television. First, the Red LED (on, off), then the Green LED (ON), then the Red LED (blinked) while the Green was still on.

I removed the back panel and saw that there were NO SIGNS OF BAD CAPACITORS on the Power Board. I plugged in the TV once more to see what would happen.

I noticed that there was a SMALL FAN which did not move when I plugged the power source to the outlet. This Fan was CLOGGED WITH DIRT.

I unscrewed the Fan from it's place and set it on a dish to act as a buffer against the main board. I then proceeded to clean it with a Vacuum Cleaner and a small Flathead Screwdriver.

Your power board has gone bad and is not supplying enough power to start up the inverters. The LED lighting at all shows that you do have standby power, but that is all. You will need to have the power board replaced. Hope this helps.
