Tv comes on and off by itself, sometimes it blinks on and off. tv is 3years old. i put all my cords on a power surge . i recently put a dvd on my tv. need help to see if i need to buy another tv?
TV turns itself on and off. It also goes through the menu that presets the channels. Then the only way to finally turn it off is to unplug it. The unit is about 4 years old and has never done this before. Checked the remote, removed the batteries, changed for fresh ones. Tried spraying bottled air into buttons (Dust?). If I depress and hold menu button TV holds to one station but you cannot change volume levels or anything else. Is this worth fixing? Thanks Gliterbechba! I had the same problem today, TV turning off and on seconds apart. Took your advice and found the wire connecting the manual controls to the circuit board and unplugged it. It was a piece of cake, no problem. TV works fine now, just always have to use the remote which I did anyway. Thanks again. my tv comes on by itself, its stays on for several minutes then cut off. sometimes it blinks on and off. my tv is 3 years old. i need to know do the sensor light suppose to be on or off when the tv in off. i recently put a dvd on my tv. i neeed to know what the problem is, or do i need to buy another tv?

Sounds like the power supply board is dead. Probably has a blown power line fuse on the board. A power surge will sometimes blow the fuse and protect the board from damage. Replacing the fuse will restore the TV if this is the case. Most times though, the supply has a blown part that causes the fuse to blow and your only option then is to replace the board.
Try disconnecting all of your HDMI cables and plugging the power cord of the TV into another wall outlet. If this resolves the issue, you may have had a small power surge from either your wall outlet or one of your source devices. It is recommended to connect your TV to a surge protector if you haven't done so already.
Check your power connection and the cable going into the TV. Also, if it is plugged into a surge protector, test to make sure the surge protector is working and that it hasn't tripped. If it is getting power, but it still refuses to turn on, take it to a tv repair shop for repairs.
Sometimes when the TV recives a brodcast signal for a new update to the mainframes firmware, it will have to turn itself on to install/recive the update and aslong as it is connected to a power source it can do this. hope this helped answer your question. Have a good day :)
After the power surge , the TV went on protect mode.
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
ensure that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem with no receiver box
or dvd connected.
If that does not work, and you keep having a flashing
led on front of the TV, and tv turning off by itself after a while,
that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.
internal circuits are jammed because of electrostatic
charges accumulating on capacitors, or because of a wrong voltage read
by the main chip on your monitor controller board. this started the
2 The protection circuit detected a wrong
voltage or abroken contact, identified an internal fault and kicked in
, startingthe flashing light.
If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
that can occur after power surge on a rear projection are a blown capacitor on power board, a component on ballast board has blown, or a fault on Digital board had occurred.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.
You may have to hard reset it by unplugging the cord itself and plugging it back in. When power comes back during power shortage, there may be a power surge rushing to the modem/router causing it to behave abnormally. Also, you may want to put power surge protection on it as it may damage you modem/router as i did mine.
The STANDBY light is flashing on the television and there is no picture or sound.
The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.
Turn off the television.
IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
Turn on the television.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.
