Customer Question

I have an LG TV it'a about 8 years old.Last week I turned it on and stayed on for about 2 or 3 seconds and it turned off also no voice. I returned it on and it worked good, however it is
still cutting. Any ideas besides a new TV? Thank you, Paul=

Hello and sorry you're having problems. When the set turned off- did the power light physically turn red and the set actually shut off? Also, how long is it working for now before shutting down?

Do you have any electronics repair experience, and are you looking to repair the set yourself?

Are you able to see my reply?

I received your reply. No will not repair myself. I was hopping you might have an idea as to the trouble and location of LG tech in this area. Thanks

Paul, respectfully- your reply came in 24 minutes after I engaged the question. I was not online waiting for 24 minute for the reply- I waited about 15 and went to do something. I am now online, and can talk back and forth to you as needed. The TV's power supply board is what's at fault here. These boards are known for capacitors going out of spec and causing the TV to shut down. To fix this issue requires either a power board swap, or the board you currently have to be rebuilt. The average cost for this type of repair on your TV is $250 parts and labor. If you're looking to swap the board yourself- it's plug and play- meaning no special tools are needed to replace it- as the connectors all plug in. However if you're not looking to repair the set yourself, a shop can be located at the link below:

To replace it you need nothing more than a screwdriver and to remove all of the screws on the back of the TV- remove the rear cover, and then unplug the connections on the power board within the set. This is the board that directly connects to the AC Input jack on the TV. Installation of the board is the reverse of removal.
