I have a LG TV 47LD650 that has picture but no sound out of tv speakers. If I connect an optical cable into the output and use a sound bar, will it still produce sound?

You have to go to setting and change the audio output to TV speakers for the TV speakers to work,, but, if you use a sound bar with optical have to set it also .. mine works the same way,,

This kind of symptoms is cause by faulty(leaky/dried) electrolytic capacitor in the power supply section. In the first stage of symptoms warm up will make itself stable and the unit will power up after a few attempt of plugging and unplugging from the outlet but it will get worst, time will come that the unit will not power up at all.

Leaky capacitor has a physical indication of fault like bulged/dome at the top and can be easily identify like in the sample picture below.


Leaky capacitor with dome at the top.

Dried capacitor has no physical indication of fault, you must have a capacitor checker to determine its condition, if not available you should replace all electrolytic capacitor in the power supply section. It will not cost you much because it is one of the cheapest parts on that board.

We have lost our digital abc and channel 10 1hd and 11, how can I get them back, is there a default?

The problem is your digital antenna they lose signals all the time. Try moving the antenna around, if that don't work go to radio shack and buy a signal booster.If you programmed your LCD while the signal was low it wouldn't have picked the channel up also.

LG 8100

Hi Imatt015,
This is called "restarting". The mobile when restarting turns off and turns back on just as it happens to our PC when we restart it. This may happen at times when the OS of the mobile has encountered a problem or if there is some updates to any software in the mobile.
