If it is at the same time every night then it may just be a setting or a software update.

Check in your menu for the ON TIMER settings and make sure there is not a timer set for that time.

Otherwise, it may need the main board updated or replaced.

Tv is turning on by itself during the night...do not want and need to find out how to stop this from happening


Must be on stand-by for this to happen. Switch it off properly if you want undisturbed sleep.
Go to settings to change..also might need to do an update.

Lg 55lh90 no sound


The set itself may have a hard reset--if what happened was a outage--unplug set, box if used, receiver if used and wait a while--plug all back and wait for any and all to come up--reboot to see if it helps or not.

If no sound via any input like a DVD etc check that speakers to set did not get switched to off by that event.

Failing these the set may have a audio circuit problem.

Tv switches on, on its own


I do not know how old your tv is, but I can tell you that if it is more than a couple of years old, the back cover needs to be taken off and blown out with clean compressed air. If your tv has quiet cooling fans on the back, they are notorious in all plasmas and lcds 32" and above for attracting dust and lint from the ambient air. This along with moisture will cause the dust, lint and moisture to settle on critical components that cause tiny static discharges between components that can produce what you described. Another thing is and this is from my own experience is that even the tiniest pest like a roach or a spider, like I said depending on the age of the tv, can cause similar problems my traversing across the components. I had an RCA that would turn on by itself and change channels by itself. All in all the one thing you can do yourself is clean it out of all dust and debri. Good luck and God bless you. Robert
