Question about Televison & Video

2 Answers

I have a Mitsubishi 1080 HD Medallion 48" projection TV that was purchased about 5 years ago. The green light next to the system reset button is flashing quickly and the set will not turn on. I have tried unplugging and resetting the tv as the dealer and manual suggest, but this does not help. For a while it was turning on and was okay for a week or so. Now it won't turn on at all.

    The blinkiing is continuous.

    What would it actually cost to have an authorized repair service come to the house to replace the 4 caps?

Sir,

On those TVs it is normally a bad DM module board/convergence check out this forum it may help you a little more....

http://www.hdtvoice.com/voice/showthread.php?t=20219

4 bad capacitors in the DM module is not letting your TV set download it's software. They must be replaced to fix it.

Done several of these...you'll need (4) 1000uf caps at 35 Volt rating, and a TV Tech to install them.
Get a Mitsubishi Authorized servicer out to your home.

And you should not need a DM module to fix it....I've only had ONE out of 30 that required the DM module...but that's because the customer waited too long to get it fixed.

thanks
good luck

    The constant blinking green light means 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)


    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.

You need to replace 4 capacitors on the "DM" board. They are 1000uf and 16v. The board is located under a metal shield on the left side of the set (looking from the rear).
