WD-62525 - red status, lamp or ballast fan

I've had my 62525 for about 3 years now. About 6 months ago I replaced the lamp. About a month after replacing the lamp, the TV failed to come on. After pushing the power button, the status light blinks red in a 1-3 cycle. Menu + Device gives me a code of 37, "lamp or ballast fan stopped". At the time, I took apart the back of the TV to see if I could see anything obviously wrong with the fans. I did not. I put everything back together, and the TV magically worked fine for a few more months. Fast forward to two weeks ago.

Two weeks ago, the same symptom returned. This time, the TV won't magically repair itself. I'm getting the same status code (37 with menu+device). Had a technician take a look at it yesterday, he said he "thinks" its a power supply problem. He said he'd need the TV for two weeks and the estimated minimum repair cost is $800 (man I can buy a nice LCD for that much...).

So, since I'm out of warranty, and I really don't have the spare $800+ to hand over to a shady repair guy, where do I start troubleshooting for a DIY repair?

Any help is greatly appreciated.

Is the red light blinking or steady?
Have you tried to reset the tv?

System Reset
If the TV will not respond to either the remote control or the front panel controls and/or will not power Off, press the SYSTEM RESET button with a pointed item like the end point of a paperclip. The TV will turn Off and the TIMER light will flash quickly for about one minute. When the TIMER light stops flashing, you may again turn on the TV. The changes you made the last time the TV was on before you used the SYSTEM RESET button may be lost, however, the changes that were previously saved are not lost.

Try this and let me know.
Good Luck.

SOURCE: I have a Mitsubishi WD-62525.

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

SOURCE: Tv powers on then ''clicks'' off

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

New member here. I have a 62" DLP Mitsubishi model #WD6252. I've already replaced my lamp AND ballast and continue to have the solid red lamp status indicator. I've made sure the connection from th


Your color wheel is failing or has failed. the red light ONLY means the lamp cannot light or was forced to shut down. it means nothing about the lamp or ballast specifically.

If your color wheel isnt spinning up correctly or you have a stuck fan somewhere, the lamp will be shut down immediately upon startup.

Id check to see if the color wheel is stuck or if its getting stuck.

WD-62525, continous amber lamp light. No picture. Lamp is good.


Hello:

Make sure u replace the lamp cover as the safety switch need to be closed to make the set work. If new lamp did not repair your problem , then it may well be the Ballast Board, Sometimes call the Lamp Driver.

My wd52327 turns on and than turns itself off


Thats a very common problem which means that the capacitors on the power PWB have most likely failed. You can get the repair kit which has the replacement Capacitors and step by step instructions with detailed pictures on how to do the repair . Heres a link to the repair kit for your model.
