Power supply may be fault. If you are not familiar with electronics repairs better take it to an authorized service shop to check it.

The steady blinking light means there is no specific code.

    Check for bad solder on
    convergence module. May have bad stk's. Do not neglect looking
    for bad solder on d signal and defl boards. Mitsubishi is very prone
    to bad solder.

Mitsubishi dlp tv model wd-62627 wont power on when i plug tv in green light flas then will stop then i try to power on tv after after green light stops flashiing after oabout 30 sec red lamp light co


Inspect the lamp first to see if shattered--set has a self check feature also:

Mitsubishi TVtroubleshooting
Here's something that might also be useful. After you turn on the set, and getthe regular red blinky lights, hold down the Device and Menu buttons togetherfor about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filtercover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cablebetween FMT and Engine disconnected

Sounds like your DM board or convergence chips have failed. Check the site www.TvRepairKits.com for a fix or call in a local repair shop

Mitsubishi WS-55857 turn on/auto turn off problem


After it shuts off, you need to get a code from the tv by pressing the menu and device buttons together for 5 sec. A code will flash at you made up of 2 digits. Example. 2 flashes a pause and 2 flashes points to a convergence failure. If this is not your code post yours and I will help you.

Status indicator flashes 3 short times, then one long red flash


Once the status light blinks 3 times, this is an indication that there's a problem with the lamp. The lamp may need a replacement.

If you replace the lamp, but get the same problem, check the inverter board.

If you're not sure where the inverter board is, then you may need to contact a pro for your safety.

Good luck and have a good evening!

Press power button green light comes on.But no picture no sound,


I have had my WS-65511 fail like this, first at 4 years, second 2 weeks later, then 3rd time yesterday (4/14/2009). In past, the tech replaced a thermal sensor p/n 299P313010A (but Mitsubishi says that part is not for WS-65511 and that it does not have a thermal sensor - go figure). It is a white rectangle with about 30 pins in 2 rows and is soldered onto a board in the TV. List price is about $25. Might be your problem.

If the green front panel LED blinks continuously and the TV never comes on, its an issue with the "DM" board. When these TVs are first plugged in, the green LED should blink for 30 sec. to a minute or so. This is the TV booting up, reading its software. Mitsubishi has been having problems with this circuit for several years. In may cases the only permanent solution is to have the chassis rebuilt by Mitsubishi at considerable cost and inconvience. The chassis may have to be sent back to Mits for this rebuild. Call Mits and ask for help.

Tv wont turn on get audio then tv shuts off timer lite blinking


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.
