Tv flashing stand by / timer

I am sharing four cases in which your tv either turns itself off or appears to turn itself off.

TV appears to be off

• You using your tv as a monitor or your pc is in sleeping mode.
• Your cable or satellite Box is not outputting a signal.

TV turns iteself off

• The sleep timer is set.
• The off timer is set.

Your tv appears to be off:

If you are using the tv as a monitor If you are using tv as a monitor and the stand-by light only
blinks for a few seconds when you press the power button,your pc is in the sleeping mode. To take your pc out of sleep,press a key from your key board or move the mouse.Tv turns on.

If you are using TV with a cable or satellite Box

If you have a cable or satellite Box your Tv may appear be off because the cable or satellite Box is not outputting a signal.Press the guide or info button on the cable or satellite Box remote control.

if the screen displays info or guide data,the problem is caused by the Box,you must call your cable provider.
if screen does not display info data,change the source on your TV.

-your flashing green light is informing you that "power supplier" in TV body is standing in emergency mode-need to repair !

I need a solution for this problem..I can't get the tv to come on to go into the menu and clear the timer...Someone have any helpful info...I have the comcast box on the tv..I took everything off the tv
and plugged it in thinking atleast the snowy screenwill come up and then I could see the menue and fix the timer but that didn't happen. Left tv plugged in and cable hook ups on figured eventually the timer would clik off and tv would come back on..No such luck....Can anyone help me with this problem

well it's due to ur cable connection is unable to receive or ur dish tv

The light in your TV may be dead. Also- is the TV hooked up properly?

Try this (may not work):

1. UNPLUG power from TV at wall outlet.
2. Turn ON the TV (with no power cable plugged in).
3. Plug power cable back in (at wall outlet)
4. Turn ON TV (don't use remote this time).

Hope this works!

is there a cadence to the blinking timer light?

If TV stays in stand by with audio but no video, then common faults are the ballast board, or a fault on digital board.

If the led stays blinking , and tv turns off then the TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also 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.

1The 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 protection circuit.

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.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


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.

I will need to know the model number of your set to help you as well as if the light blinks a certain number of times in between pauses. Please respond to this same post.
