If your LG LED TV suddenly turns off, there might be a power supply interruption. Check the power control settings. Also, verify if the auto-off function is activated within the time settings. If the TV is on but not receiving a signal, it will automatically turn off after 15 minutes of inactivity.
What to do if my LG LED TV has no image and no sound?
If your LG LED TV isn't displaying an image and there's no sound, first ensure that the TV is actually turned on. Then, check that the power cord is properly connected to a functioning wall outlet. You can also test the outlet by plugging in other devices to see if they work.
How to fix an LG 86US340C0UD remote control that is not working?
If the remote control isn't working with your LG LED TV, make sure nothing is covering the receiver on the TV. Also, check for any obstructions between the remote and the TV. Try replacing the batteries in the remote with fresh ones.
What to do if my LG 86US340C0UD is not detecting HDMI signal from PC?
When connecting your PC to your LG LED TV via HDMI and no signal is detected, try turning the TV off and then on again using the remote. If that doesn't work, reconnect the HDMI cable securely. As another option, restart your PC while the TV is powered on.
Why is my LG 86US340C0UD LED TV making cracking or buzzing sounds?
The cracking noise you hear when watching or turning off your LG LED TV is typically due to the plastic thermal contraction caused by changes in temperature and humidity. This is a normal sound for products that require thermal deformation. Also, a low-level noise might come from a high-speed switching circuit supplying a large amount of current; this does not affect the TV's performance or reliability.
Why should I not mix new and old batteries in my LG 86US340C0UD remote?
Avoid mixing new batteries with old batteries, as this can cause them to overheat and leak.
