Good day!Follow this D.I.Y procedures to find the exact problem of your TV.

  1. Remove the back cover of your TV.
  2. After that,find the power supply board.
  3. If you already found the power supply,plug-in your TV and power it ON.Check the input voltage of it,using multimeter (AC range).If the power supply have no input voltage the problem could be the power cord.Replace it.
  4. If the power supply have the input voltage,try to test the output voltage if have 5vdc for the system and logic supply,12vdc for the sounds and 24vdc for the back-light inverter.Use your multimeter tester (DC range) to test that.
  5. If the power supply have a voltage outputs such as 5vdc,12vdc and 24vdc and the problem is still there.The problem could be the main board.Replace it with the same type and model # because the main board is no very difficult to fix and its very sensitive.
  6. If the power supply have no output voltage or the voltage is too low,just ignore the step # 5 because the problem is not on the main board,its on the power supply board.
Check the following to fix the power supply board:
  • Fuse: Check the fuse if it is busted or blown.
  • Power transistor (regulator): Check the regulator if it is shorted or leak.
  • Resistor: Check the resistors specially the one that have a low resistance that near the power regulator.
  • Capacitor: Also check the capacitors if it is leak or bulging top.
NOTE: If you found any defective parts or components that mention above replace it with the same value,type and ratings.

I hope this solution will be helpful.Thank you and good luck.

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

LG 32LH2000 My TV was turned of last night in the usual way, the power turned off on the remote control, then the power supply switched off and the plug removed. This morning I attached the power...


most LG have a "vacation switch" on the bottom right hand side of the set very near that standby light.

it is placed poorly, where you can accidently click when grabbing the TV to move it or swivel it.

it is a toggle switch, a "master power" switch.

you may have bumped it to the off position. flip the switch, your standby light will come back on.

Tv shut itself off while I was watching.


The power supply will need to be replaced. You can get them for $30 plus dollars and solder them in.

Tv stuck on standby


Power supply probably needs to be replaced if you don't even hear the relay click after the power is switched on.

Did you get your tv fixed? It may be the Sub power supply unit. If the main supply went out it would not light the display at all. Yes it is time for th repair shop. Good Luck.
