to eliminate the problem just select the mono sound disable the stereo signal.so that your tv sound will be stable.this happens because not all tv stations are broadcasting on stereo signal thats why your tv keep on switching to mono and stereo base on what signal it receives.plus the signal being feed by the cable provider sometimes they are not stable enough to give the stereo signal so better select only the mono sound...tnx hope i helped you..

please rate my help!

I have never heard of any LG TVs having a fire issue.
LG added this switch to help save electricity. "Going Green".
You see, this On/Off switch was added to kill the power to the TV when not in use. This switch stops the TV from consuming power by not giving it power to be in a “Stand-By” mode.
If your TV does not have this switch, you could simply unplug your TV to give you the added satisfaction it won’t catch fire.
I hope this information has helped.
Good Luck.

A common issue with this model is the control key board (the key input board that has the buttons on the cabinet of the TV).

This board can cause a lot of issue ,from changing channels by itself,to intermittent shut off, also sources cannot be switched or they switch by themselves.

The less common issues would be the remote eye or the main board.

If you give the full model number and the product code from your TV, I can give you the part numbers.

I am currently having the same problem, there is a setting (which I have not found again yet) to change into a mode to enable quiet startup, so you dont accidentally turn devices on when their volume is up loud, I believe this could be the cause but as I said I am still looking for that setting! Constantly have to keep changing speaker output in Simplink every switch on

hi,
you can get the spare part in lg service cener...note down the model no and the tv inch size and ask in service center they would give you lcd screen...it better you fix it in service center itself....


thank you

hi sir
as it is not giving the perfect picture so it might have gone wrong in the screen pixels better to check the lcd screen and me sure the pixels went wrong it can be also coz of the water vapours please keep the tv away from water or windows etc.there might be a circuit problem which may not be working .
thank you
