Are you changing channels with the remote? Try taking the battery out of the remote, its buttons might just be getting stuck? If, when changing the channel by hand, it persists, then it is an electrical problem, and you should contact LG to see about getting your unit replaced.

Try looking for the remote sensor. It should look a little like a camera lens or little red tinted window. If you cannot find it just give the entire front of the TV a good cleaning. Finger prints and dust build up can interfere with the signals. Do the same for your direct TV box.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here.

It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should be troubles hooted. Contact any service technician. The circuit will differ with models and versions. Type in the brand name of your device, in the search box [at the top right] of the display window and the Search will start at once as you type in, and will show you all the related posts.

Televisions now are equipped with a diagnostic circuit that send a low voltage , low frequency signal throughout your set when you turn it on. This is to detect any problems with the circuitry and protect the good circuits.. It started out with a component that wasn't working properly but finally returned the signal. With continued use the component finally burnt out and now your set is going into standby mode. The blinking Green light is a code X amounts = a certain problem. Look up the make and model on the internet and it will give what 2 blinks, three blinks, etc means.. It could be anywhere in the set but the blinks will pin point to the board more than likely. Probably in your power board and if you are lucky it is just capacitors which you can replace yourself if you are a DIY 'er. Check out their web site and find out what your problem is first.

Is the on time function on? Go to the menu go down to time then across to on time if its on turn it off.

Try another HDMI source (borrow a friend's BluRay for example} to confirm it is the TV at fault. If it still doesn't work, the TV needs a main board replacement because all the HDMI circuitry is on the main board. this usually happens after a power surge or lightning storm, and a near hit is all it takes, Sometimes, if you have a Satellite Receiver it too might be damaged on its HDMI output. So 1st try another source..IF you replace it yourself be sure to find the right board by using the TV's service # example 32LC7D-XX.XXXXXXX.. The letters where I have Xs are very important and must be matched,

If other inputs show no problems and you are not using a cable box or satellite receiver, etc. just off air antenna, something on the main board is failing. please double check other inputs again.

Check the wiring to the other speaker and make sure it's connected
Using a multimeter set on ohms check the resistance on the speKer that is not working and compare it to the one that does work
If it's the same then it's not the speaker but the supply to it that is faulty

yes replace the button board as it sounds as though you may have a button sticking or it may have a short. you can remove board and buy a can of compressed air and blow it off to remove all dust/dirt to see if that may help. if that does not workk next sokution would be to replace it, here is a link to ebay part. hope this helps. http://www.ebay.com/itm/like/360768561056?lpid=82 merry christmas and happy new year.

Check and replace the main system control memory IC. It is faulty.

the sound board has gone weak so would check the capacitors for a weakness they will probably be blue type as they re used most for sound boards change them for black or green type 105c type not 85c.
