It can be the main board, power supply, backlights inverter boards. You need to do the inspection inside for any sign of bad caps, loose connections, voltages. Please read my guide first, also go to www.shopjimmy.com to see what the boards look like.

Hello,

We hope to help you with your issue. But first allow me to give you some entry level steps to do.

1. Unplug the tv from the wall outlet or power strip
2. Wait 15-30 seconds
3. Plug it back into the wall and give it a whirl

If that fixed it then your tv went into hibernation mode or DEEP SLEEP thus could not be turned on.

If that does not work let me know and WE will find you a answer to your issue.


Thanks,

rulds2008

LG 42LC7D TV does not want to chg channels after 5 min of use


There are some inductors that are out of spec. LG's original SB said to replace some of these with a jumper, but it only lasted a couple months.

You need to have the Total Main Assy replaced.

Convergence issue


You can go back to factory settings by pressing and holding the ACTION and POWER buttons on the TV while it is on. A CHK screen will appear and when it does release the buttons and then power the set off then on again. This had reset all settings back to factory conditions. You will have to reprogram any channels into memory after this.
