If you broke one of the base stand screw you will need to do as follow:

Remove the remaining screws of the stand and try to remove the stand, if you cant you will need to remove the back cover of the TV and then you will be able to remove the stand, remove the broken screw and put it all back.

It is pretty easy but if you feel you cant do it let me know and I can give you a detailed step by step guide.

Hi, I believe it is the power supply(transformer) or power board. Have it checked by a Techy repairman. Good luck.

If you have the original LG remote then it should be the 2nd button under the TV button on the remote on the left side.

You can't connect speakers to the TV. You will need a Audio Receiver to connect the speakers and TV to.

With the onset of more and more TVs being hooked up to cable, TV manufacturers didn't need to make the tuners as sensitive because the signal from the Cable Co. was much stronger than the over the air signal. If the other TVs are older they may be just sensitive enough to lock onto the channel signals. You could ask your cable provider to check your available signal in the house to see if there is the proper amount of signal. Some channels can inherently be stronger and when "block converted" (put where the cable company wants the channels) all come thru but some are a bit clearer.

This is an optical digital audio output that uses optical fiber with Toslink optical connectors at both ends, from there it comes the name, since your wireless headset has only analog audio input, you'll need an optical digital audio to analog audio converter, to connect your wireless headset to your TV.

We attempted a hard reset on the unit but you were not at home to try it. Please call when you are near the set so we can troubleshoot the problem.

Hello
The power supply board [SMPS board] of your tV is faulty. Normally, nor repair to this board is intented, or should be done. This board should be replaced as card basis. Plasma TV's panels are very sensitve to static or over voltages. So it will be best to replace this board, rather than maing "surgery' to it. In most cases, the components in this board will be very difficult to get from open market. Frome your description, the SMPS transformer on this board is faulty. You can't get it seperately. Just repace the power supply card. The picture of the card is atteced here. Two snaps of different angle is shown for your reference. OK.

Hi, Check the plug that it is in properly and that there is power at the plug. If all is good go to repair man. Also replace battery in remote. Good luck.
