Your TV sounds like its signal board has went out and will need replaced (This is the most common cause of the problems you describe!)

Have a misubishi ws55859 green light blinks will not turn on it all started when the tv was unpluged


The dm board power circuit has gone bad and would require many capacitors to be changed. This board is a box (metal grey) on the left extreme as viewed from rear next to input connector board. It is not recommended as an abinitio DIY Project. Caps faults are difficult to find and require an ESR meter. Call for professional help and should cost 180 to 220.

Timer light on projection TV blinking and TV won't turn on


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.

HDTV CABLE NOT HOOKED UP/WORKING


COMP 1 and 2 are for 480i/p sources. Hook it to the 1080i capable on the back. Also make sure the HD DVR is outputting 1080i not 720p. The Mits can not disply 720p and will show a scrambled screen if you try to.

Diamond shield


It seems these TV's are going bad right and left. I would look on Craig’s list for a cheap/free 55" Diamond TV. Not sure what you would do with the left over TV. I just picked up a 55" Diamond for free and hope to fix it. If I don’t get it to work, you can have the screen (California).

No Picture from Component Input #1 or #2 but do have audio via Surrond Sound


Simplest thing would be that your component cables are not HU'd correctly. Having them reversed would do this.
