How to master reset a TV?
Also, if you have a Smart TV that is connected to the internet by WIFI, try updating the system bios or the TV software that controls it. Look for TV update settings in the menu. Try the reset and the system update and if that does not FIX your TV, you may have an issue with a component in the TV.
If all the above has failed to work, and you have checked and rechecked that the components attached to your TV ARE working properly, and have tried the reset and update options, you may have an issue with the TV itself. You could have a power board issue or other board issue. To fix a blank TV screen or find out if a board in your TV may be bad, try reading this page here about TV has sound but no picture.

I have an Orion SLED4668w LED tv. Video and audio works fine with all HDMI connections but when I plug in an antenna or anything else into the coaxial input the tv will suddenly turn off and on by itself with a white line across the screen, sometimes at the bottom, then the middle, then the top. This erratic behavior will continue unless I disconnect the antenna cable from the coaxial connector. I’ve tried different antennas, cables, outlets, even a cable by itself all with the same result. I also tried resetting it. I am able to go through the process of auto scanning channels but after it’s done scanning and tries to go to a channel the process repeats itself. Help!
I have a Luxor smart TV which works perfectly well except when I try to connect to the internet either via WiFi or wired the TV switches itself off if I keep the Ethernet cable in it will turn on and off until I remove the Ethernet cable
Our tv turns off every hour on the dot unless we are watching hulu, netflix, amazon prime, etc. No timer is set. We thought it was the tv but have purchased a new one and it does the same thing. We have plugged a lamp into same outlet and it never flickered. The cable box does not turn off either, just the tv.
Vizio TV VA26LHDTV repeatedly cycles on and off, when plugged in.
Without ever touching any buttons.
Doesn’t stay on long enough to even try any kind of adjustment.
Just repeatedly cycles on for about 10 seconds, then shuts itself off, for about 5 seconds, then back on.
I have a Hitachi TV 42hdx99. It turned itself off after about an hour, had to unplug and plug back in to get it working again.
Then it turned itself off again after about 10 minutes.
When it turns off the power light (red/blue) is off like if its not getting any power.
Unplugging seems to temporarily reset issue but not fix the problem.
Cath ongayo,
If using a hair dryer plugged into the same outlet as the TV, the TV turned off, you simply over-amped the outlet.
You may need to flip the circuit breaker in the room where the TV is.
Check the breaker box to see if the circuit breaker for the room where the TV is being used is not tripped.
Reset it.
Once you reset it, the TV surge protector may also need to be flipped.
After you reset both, turn TV back ON and it should be working.
For future reference, do not use a hair dryer in the same outlet as a TV when the TV is ON

Our SONY internet TV suddenly turns off while i was standing near the tv and drying up my hair. Is there a chance that droplets of water reach the cord of the tv causes it to turn off suddenly? I heard a loud pop when it off.
