    I have same tv and exact same issue. Just took it off the wall and put in shed. Lovely pucture quality and sound when it worked. Not even a set top box helped.
    No channels tune in all dropped out. Tv was not moved or anything. Menu selections appear on tv as normal and can watch dvds. Any ideas. Thanks

I have an LG 42PB4D-AA Plasma. All stations perfect except for GEM and 7Mate which have perfect picture and no sound. I've read lots of posts which indicate this is very common with this model. One...


Most major manufacturers supply manuals and software updates online so if you were to log on to the manufacturer's web site, you may be pleasantly surprised as usually, if available, one is able to download, by model number, Customer Instruction Manuals, Dealer Network for spare part supplies and updates as required.

The information is normally free of charge.

I hope this helps.

Bought LG Plasma 106cm in 2008 HD


Your screen may have either burnt out or became disconnected somehow. Sometimes, it's as simple as a connector coming loose from its port; other times, however, there's physical damage to the wires/connector/port. I'd contact the manufacturer to troubleshoot it as far as it can go on the phone. I assume that they'll either figure it out right there, or follow their protocols and (assuming it's covered in the warranty) have you send it to them for diagnostic steps. The other alternative is to simply call a professional.

Samsung TV - have sound/auto volume set to on. When TV is turned off and then on, tv volume is extremely low. Go back to sound menu, it shows "on" but if you go back and act like you are turning in on, the...


Hello Blindrid,
What I would suggest you do is Press your MENU button on the tv remote, Then down to SOUND and then Turn the AUTO VOLUME to OFF. Then come out of the menu screen.
Just to check that it has all work correctly. turn you volume upto a certain number for example 25
Then turn your TV off the turn it back on. Wait until it is displaying a picture then press the volume button Once either up or down and you should see that it will go to 24 or 26 depending on what button you pressed for the volume. This will keep your volume set to whatever you had it on before you turned the tv off.

Hope this Helps Please leave a thumbs up.

Cheers
