It sounds that there is some loose connnections. Check all the plug connections for any loose. Re-seat than once.

Remote with TV stopped working for vol, AV, and mute. Only power button works. Used new Batt; no change. Used buttons on TV; none work there too. Is there something broken on TV?


If the buttons on the TV -and- the buttons on the remote don't work, then there's definitely something wonky with the TV.

The good news is that the power works and the picture looks good. That rules out a bunch of things. If you don't mind tinkering, replacing circuit boards on TVs is pretty straight-forward -- just take off the back, unscrew the offending board and replace it. You'll have to do a little research to narrow down to the right board to replace -- it might be this key controller board:

I have a Mitsubishi 73"


i would suspect your control buttons on your front panel on the set have become shorted. specifically the volume buttom down. This is freezing you control functions. like someone is holding the volume down button all the time. or intermitantly. this cuircit board is on front of the set. I have seen this problem a few times at the shop. The common repair is to replace that button assembly cuircit board. I believe the last time it cost the customer around 85 dollars, but like all things depends on the part and the technician that puts it in.

My remote Stopped working with my TV but still works with DVD player. I have a new universal remote and it will not work as well, what part Do I need to replace?


You may want to try a “Hard Rest” by unplugging the power from the TV.
While the TV is without power, one at a time, push on each of the buttons on the TV & listen to hear them click (there may be a button stuck down).
After at least a few minutes have passed, plug the TV back in. Sometimes the TV may power on by itself and other times it will may not. If the TV did not power on by itself, push the button on the TV to power on the unit.
After the unit has power on wait about 30 seconds. Now point a known working remote at the TV and see if it is working correctly. You could test your LG remote on another LG TV at home, a neighbor’s house, and or at a store.
If the TV does respond by using the buttons on the TV but not with remote control, the problem could be with the following.
Remote Eye board and or the Main board.
I hope my information has helped you.
Good Luck.
