LG Volume to 100 by Itself - will NOT respond to remote

I have a 42" LG LCD 1080p television and it's great. I've only had it 6 months but today I experienced a heatlhy glitch. While watching a show a box would pop up every 5-10 minutes that said "THIS FUNCTION IS NOT AVAILABLE". I thought maybe my son was pushing the remote buttons but no one had the remote. Then out of nowhere the volume popped up and prompty climbed to 100. It is currently stuck there. The TV does not respond to it's own remote let alone my time warner cable remote. I can turn the TV on from the side panel but cannot change channels or volume level. All I get is snow and an ear piercing 100 volume level blast of noise. Is anything wrong on the inside of the TV? I called LG who were no help. Any suggestions appreciated.

Re: LG Volume to 100 by Itself - will NOT respond to...

It's hard to diagnose without a model, but, given the problem I would say it is a 42LC7.
If it is, then, it needs a modification in the main PCB. We used to jumper coils at first, now we have to change the main PCB.
It's less than a year old, it's under warranty.

I have a 42 inch LG 1080p led flat screen and I will turnm the volume up on it and after about 15 min it automatically cuts itself back down how do I fix that

Check your remote for a stuck button and the key pad on the tv ( unless the tv has a touch panel ) If both check fine, go into user menu and see if you have auto volume turned on. If this checks ok then you have a faulty main board.

Philips 42PFL7422D/37 42-Inch 1080p LCD HDTV Picture went out but still have sound. Any tips on how to fix it?

If the backlight of the LCD-panel does not function, (no picture) then Master and/or Slave inverter are defective. Inverter boards are screwed to both sides of the LCD display, if they have revision 1.2 boards then they will need replaced with revision 1.3 boards.

LG 42LCD less than 6 months old, picture is flashing. What could be wrong?


If you have the input connected to the HDMi TV, there is a chance of picture getting flickered, if the resolution send by the device and the TV is incompatible....

If the receiver is set to send the signal at the frequency of 720p and the TV is set to operate at 1080p or vice verse then the picture would flicker..
In the settings in the TV,, try setting it to auto rather than 720p or 1080p, this should solve your issue..

If you were not connecting using the HDMi and if you use other, please leave me the details regarding the cable you use as a comment and ill respond you for the comment..

Lg 42" hd 1080p

This could be bad capacitors on the power supply board. My LG 42LB1DR has a known problem with this and I replaced the four bac capacitors myself and saved 5-6 hundered dollars that I was also told that it would cost to fix. I fixed for under 10 dollars and about 20 minutes. LG knows about it but they dont really want to admit it. My TV was only 26 months old when this happened. The four capacitors are made by Samxon and are 2200uf @ 10v. They are junk so even if you have the entire board replaced for say $200 its just going to happen again. They need to be replaced with a different brand.
