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.

Mitsubishi LT-46149 power lamp just flashes and tv will not turn on. Tried the reset and unplugged overnight, also I do wait for the "boot up" still just have a flashing power lamp. Any ideas?


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

Timer light blinking and tv won't turn on


Not much info to go off of, and the video is a bit blurry. Try unplugging the tv for a minute or two, make sure to leave it unplugged to allow power to dissipate. Then try again. Otherwise I would suspect power supply problem.

The red "on" light is blinking and the TV


a suggestion: unplug set and try to turn on again; if power light blinks does it blink in a sequence?

3 blinks repeated will mean a problem in the Convergence area.

5 blinks repeated will mean a short on the 140 volt line.

These are the two most common error codes.

Sounds like you took a hit. Unplug your set for 30 minutes and plug it bcck in. It could have just locked up the micro. If this does not fix, unplug the set and take the back off. Plug the set back in and check the powersupply for your 5 volts dc. If it is there, replace your main pcb.
