LG 37LG30 model won't come on after power outage. Red light is on but we can't get the TV to turn on.

Good day!!!


Red light it means that you have power on the TV but the system is stand by due to faulty parts...

Normally if your TV is on standby mode every time you attempt to power it ON...That problem are 2 causes its either power supply board or main board..

So lets find out...Just follow this procedure to determine what are the faulty parts..


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..

If you have any clarification or query..Just add a comment..

Hope this solution will be helpful..
