My power cord was unplugged for a few minutes when we moved TV to dust and when plugged back in flashing green light on front of TV near power on/off button and no picture or sound. Attempted to push reset button to no avail, small green light keeps flashing. Unplugged TV for 3-5 minutes and plugged in back in at wall connection and green light continues to flash.

On the signal board replace the caps by the 5/9 volt regulators. c2p04 is the main culprit. 6 caps in total can be changed. I believe c2p05 also.

This just happened to our TV as well. TV was working, we left the room for a few minutes, and when we came back it was off and we couldn't get it to come back on. Green light flashes for several minutes...


try unplugging the tv for a few minutes and see if that does it. if not sometimes there is a reset button on the back. there could be dust inside the back cover that is also shorting out...last resort though. Good luck1

Mitsubishi WS-55807 Won't Turn On


The TV is on protect mode. The clicking sound is the protection switchthat keep turning the TV off to prevent further damage, this happenswhen a fault had been detected.

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

Alsoensure that the fault is not coming from a faulty receiver box sendingbad signal, check if you get same problem with no receiver boxor dvd connected.

If that does not work, and you keep having a flashingled 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.

1Theinternal circuits are jammed because of electrostaticcharges accumulating on capacitors, or because of a wrong voltage readby the main chip on your monitor controller board. this started theprotection circuit.

2 The protection circuit detected a wrongvoltage 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 faultsthat can occur are a blown capacitor on power board, aconvergence IC has blown, or a fault on Digital board.

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


If under warranty contact the manufacturer ringing the number on the user manual

Tv cuts off and green light flashes


Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.
Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!

Power light flashing/ no picture


I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.
