Question about Mitsubishi WD-52525 52" Rear Projection HDTV

1 Answer

Tv powers on then ''clicks'' off

I have a Mitsubishi WD-62525. This morning my TV would not turn on so I pressed the rest button. After the Timer light stopped blinking I pressed power. I could hear the fans start than a somewhat loud "click" and the status light starts to blink red. I removed then replaced the lamp and the the TV worked fine. I then powered down the unit and turned it back on. All I get now is the fans working for about 3 seconds then a "click" and a red status light. It blinks 3 times then goes solid then starts over. Is this an easy fix or a "go buy a new TV fix"?

Thanks for your help

After the lights on the front of the tv settle down, push and hold the menu and input (or deivice) buttons for 5 seconds. Now count the number of times the LED blinks and follow these instructions.
Cause #1 1. Self-diagnosis error 4-4, check for proper seating of the DVI cable between the FMT PCB and the DMD (Light Engine). It may be necessary to disconnect and reconnect this cable to insure proper connection. 2. Self-diagnosis error 4-4, check for 3.3 volts DC at connector J-9 pin 8 on the Engine Driver PCB, if missing check F9A06 part # 283P128050 on the Power PCB if this is open suspect the 3.3v regulator circuit on the Power PCB part # 930B921002 3. Self-diagnosis error 4-4, check for 3.3 volts DC at connector J-9 pin 8 on the Engine Driver PCB, if missing check F9A07 part # 283P128050 on the Power PCB, if open suspect it to have been opened by the Light Engine part # 939P977020 4. Self-diagnosis error 4-4, if the 3.3 volt supply at J-9 pin 8 is good and the connection on the DVI cable between the FMT PCB and DMD are secure, suspect the Light Engine part # 939P977020 5. Self-diagnosis error 4-1, suspect the Power PCB part # 930B921002

I have a Mitsubishi WD-62525 HDTV that suddenly wont turn on. Just has a green blinking light when you hit the power button. Any ideas?


I found this on another website, most likely it is your power supply capacitors.
  1. Press the "reset" button and hold for 10 seconds .... Does TV turn on and blinking green light turn to solid green.

  2. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours..... Does blinking green light continue upon plugging in the TV.

  3. Disconnect ALL devices from the TV; DVD, Tuner, Cable Box, unplug the TV for various duration times .... Does blinking green light continues upon plugging in the TV.

  4. Press Power and Menu buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.

  5. Press Power and Display buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.

  6. Insure that no front panel buttons are inadvertently stuck in an "engaged" position.

Diagnosis: If none of the above test resolve the issue, then the failure lies in one of the following:

  1. DM Module Capacitors have FAILED.
  2. DM Module is defective.
  3. EEPROM Board failure
  4. Power Supply failure.

the status light blinking red means a fan (the unit hs 4 of them) has failed. you need to determine which one. use the self diagnostic function:
Error Code Operational Check
Note:
The TV must be in “Shut Down” and not manually switched Off, to perform the Error Code Operational
Check. When the TV is switched Off, the code automatically resets to “12” No Error.
Press the front panel “DEVICE” and “MENU” buttons at the same time, and hold for 5 seconds to
activate the Error Code Operational Check. The LED will then flash denoting a two digit Code.
Note: The front panel buttons must be used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
Example: If the Error Code is “32”, the LED will flash three times, pause, and then flash two times.
• The Error Code is repeated a total of 5 times.


and read the code.
35= Chassis Fan failure
36 =Exhaust (Back Cover) or Lamp Ballast Fan failure
37= Engine (DMD or Lamp) Fan failure

The lamp is either defective, not connected properly to the wiring or plugs (careful alignment required on the two connections), wrong type bulb, or the front panel is not replaced properly to trigger the panel sense switch (lower right side of panel)
