LGE LCD Remote Control no longer works

unplug tv remove batteries from remote then put them back in plug in tv and turn on with back reset

Power problem are cause by many reasons, i.e Power supply circuit, Lamp driver circuit and most often the TV detects an error cause by power surges. To protect TV from further damage most LCD TV have protection circuit built internally. If this is the reason of your LCD TV not powering On, an error data must be reset back to zero.
To change data you will need to access the service mode and change the value of lamp error code to zero (0). Entering service mode requires a trained TV technician. Changing data can cause more problem to your television. If you are not qualified to service your television, please do not go to service menu codes. Moreover below are the process, pls do so at your own risk.
* Unplug the TV * Press and hold the {VOL -} + {CH+} buttons located on LCD TV unit (not in remote control) Note: If above didn't work, alternately use (VOL -) + (TV/AV input) buttons located on LCD TV unit (not in remote control) * While holding the above buttons, plug in the TV. * The TV will turn on with the "K" or "K123" appears om screen. * Use {CH+} {CH -} buttons to go and display the service menu. Note: If above didn't work, alternately use (VOL -) + (CH -) buttons. * Search for "LAMP ERROR menu" from the displayed service menu by using "up or Down cursor" from remote control, or alternatively use "CH - or CH+ to select "LAMP ERROR" * change it to zero (0) value, using {VOL+} or (VOL -) on remote control. * Turn the set off to exit the Service Menu.

what you describe is almost impossible ..the only explaining is someone with a compatible remote control messing around with you ..so ...pay attention ..and after that if you are completely sure that this is out of case...Leave a comment and I will search for another possible cause ..

You have a pair of head phones? On the back of the TV there is a CONTROL input jack. Unplug the AC on the TV and rapidly insert and remove (fully) your head phone connector into this jack. Do this about 10-20 times. Plug the TV back in. Does the remote work? If so, put a piece of scotch tape over the empty CONTROL input jack. Dust gets in this jack and messes up the remote communication. I hope this helps.

If you wish to get some details; visit the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/Plasma TV troubleshooting procedure is given. Faults to all brand Plasma displays are similar.

Main systme control PCB. its the board where all of your inputs are in.

you need a usb memory stick with your movie etc in divx or mpeg format obviously plugged into usb port. You then need to select your input device by pressing AV button on remote control a few times and it'll go through TV,SCART, AV,DVB-T,HDMI1,HDMI2,EXT,USB

It might have been blown out by the lightening storm. that happened to two of my tvs that were plugged in during a lightening storm. they both, and two dvd players, would not work after, but the ones that were not plugged in were fine. You should unplug your major electronic equipment during a storm, unless you have a power surge plug/equipment.

Make sure the remote is set to operate your tv and not a cable box or accesory. It's in the menu

Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.
