Without proper testing I would only guess that this problem is the power supply has failed.

The constant blinking green light means for one minutes and then goes solid green, that the TV is not booting up. This is a common problem on this set.You need to remove the shield from the DM board (standing upright on the left where the DTV RF connector is)and inside you will see the four leaky capacitors (1000 MFD 16 VOLT)replace them,plug the TV in and wait 70 seconds for the blinking light to stop,then turn on the TV.The hard part will be removing the board from the TV(lots of screws and connectors,takes time)

a3d2d2a.jpg You must do some checks first:LED does not stop blinking after plug in. Verify the standby supplies, 12-volts at connector KA pin 17, 6-volts at KA pin 18 and the 28-volts at KA pin 19, if the supplies are present suspect the DM PCB part # 934C067001 LED does not stop blinking after plug in. Check C9B01, C9B02, C9B10, and C9B11 (1000 UFD 16) on the DM PCB, if they are bad replace them with part # 181P734030 (680 UFD 16 V). LED stops blinking after 70 seconds of plug in but will not power on. This model is equipped with a keyboard lock feature; this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds . LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector RF pin 4 and 5 on the Signal PCB if low suspect problems with the switches/buttons on the Control PCB part # 935D736001. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector RF pin 4 and 5 check good suspect the E2P PCB part # 934C061001.

Existen unos capacitores que con el tiempo fallan y te dan el sintoma que tienes en tu TV. Estos filtros o condensadores estan localizados en la placa DM (Modulo Digital)
Presione Aqui donde se encuentran instrucciones de como y donde se encuentran los filtros.
Las instrucciones estan en Ingles pero hay fotos tambien.

1,2 error code means NO ERROR FOUND. The set is older and may not be compatible with this set---what type of connection is being used and to which rear input?

If you do not have the service manual I can get you a link for a free online copy which contains a lot of information for free.

It can be either read or downloaded for free.

Try website like Tvrepairworld.com they sell these capacitors kits put toghether for most of the DLP tvs DM power supply board repair.Talk with them they should help u further.

Mitsubishi... | Answered on Apr 08, 2012

two ideas:

Make sure you tested the pico fuses inside the unit with the caps==two or three of them.

Also from front of set behind speaker grill unplug both plugs that go up to front keyboard--set will still work with remote===if set functions now then the reset micro switch is bad/damaged.
