Hi,how can i reset my LG 7.2 home theatre system? The unit keeps displaying (M-PROTECTION) please help me.

HI? Please check the rca cables. You could inter change the cables to see if the problem is there.

Here is LG'S toll free number: 800 243 0000. TYVM Please leave feedback

it has an overload protection reset button somewhere. try pushing it.

there is a short in the amp that needs to be repaired before the unit will operate correctly.

If you've disconnected the speakers and the fault is still showing then the fault is internal with the Amplifier and it's shutting down to protect itself from further damage.

Your only solution is to remove the cover and have a look at repairing it yourself or take it to a repair shop.

Sir avservice, I have also posted a problem about an HT502 DVD receiver + Home Theater. The sound won't come out of the speakers but only of the Plasma tv. But was working before. And the word "PROTECTION" is appearing on the display screen of the dvd receiver. But good quality picture on the plasma tv. Please help

protection error message means that your unit's fan is not working

it is a feature to keep your unit from overheating

check if there is anything blocking the fan of your unit from rotating

if problem still persist replace the fan

i would suggest turning off the system, disconneting it from the outlet and plugging it back in, the should reset the settings, please post with what you try to do.

Thanks and i look forward to your post.

Hi, Ive had the same problem and after talking to Samsung Tech Support, I re-checked all my speaker wires and thier connection... one wasn't quite making proper contact so I adjusted it and PRESTO all better!!!!!

the above is correct but you need to have the dvd player on with no disc in so "no disk" is shown on the front display. then hold down the stop button for 5 secs to reset the display mode back.
