Hi,
The lamp has already a resistance which is sense by the processor and made the unit a subsequent shutdown. It will produce an overload to the ballast board which is detected by the processor. Replace it with new one and your unit will back to normal again.
Hope I helped you.
Have a nice day!

Good day!!!


That problem is usually have 2 causes..Its either power supply board or mainboard..

Please take this steps on how to determine the problem:
  1. Open the back cover.
  2. Check the power supply output...It should have 5vdc for the main board..12vdc or 16vdc for the audio and 24vdc for the back-light inverter..
  3. If those 3 voltage supplies have encountered voltage drop...The problem could be on power supply board..
  4. If the power supply output is normal..The problem could be on the main board...
  5. If the problem is power supply you should check if the capacitors are bulged on the top and try to replaced it..If you can't do that you can purchased new power supply board..
  6. If the problem is on main board there is no D.I.Y repair on that so you need to buy a new main board that fits to your TV..
Hope thissolution will be helpful..

Thanks for using fixya...

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.

Runs for 10 minutes and goes off the display. What could be the problem


  1. Go into your “Time” menu in the TV and make sure noting is turned on to automatically turn off the TV.
  2. Make sure the TV’s power cord is installed correctly into the back of the TV and into the wall outlet.
  3. Sometimes using a different remote to channels on the cable/satellite box can cause the TV to power off. This was common with the Motorola boxes because some of their remote codes were similar to LG power off code. This issue was resolved by a firmware update on the TV.
  4. When you power the TV back on and the Channels are erased, then the problem is due to a bad main board and need to be replaced.
  5. Other than that, it could be the power supply and or the main board power off the TV. The only way to tell with a LG service remote and some TV repair tools.
I hope this information has helped you.
Good Luck.

Lg 52 in lcd turns off then back on when your


The problem lies either in the power supply or the main board. But most probably it lies in the main board. These boards communicate in switching on the television sequentially. The power supply sends a signal to the main board when AC power is supplied and puts the television on stand-by. When the TV is turned on, the main board sends a switched command to the power supply to deliver it's output for audio and video processing. At the same time it turns on a supply voltage for the backlights.

What probably happened is, the signal sent by the main board to the power supply is being switched on intermittently and causing the turning on and off of your television.
  1. Remove the back cover of the television to check the power supply and the main board. The power supply is the one with transformers on it and located at the center while the main board is the one where inputs are being connected to and located at the lower right back of the television.
  2. Check the power supply for any swollen capacitor.
  3. Turn on the television and check if the LED on the main board flashes as the TV turns on and off.
Please inform me what will you find above and if you can do electronic repairs. Just tell me if you need guidance in replacing parts for your TV.

Tv turns off randomly


it is possible your neighbor has a universal remote and is playing tricks on you, or it could be over heating problems.

It is the power supply. Replace the C97, C19, and C16 Capacitors with 2.2 uF ones.
