I have been struggling to repair my 52725 for months. It had the GLOD. I finally got it fixed by replacing boards, caps, and fuses.
I finally got it to work properly over the weekend and was watching beautiful HDTV in my basement on the newly repaired TV. I was ready to bring it upstairs to the family room on Wednesday. So, I installed the chassis and put the cabinet back together. I turned it on one more time to make sure it still worked. It did. When I got it upstairs and turned it on, it wouldn't turn on. I got the red status light. It blinked 1 and 3. The error code I got was code 37. I took it apart and saw a couple pinched wires under the chassis that were going to a fan. I unpinched the wires. They looked ok and not broken. But, I still get the same error.
Error code 37 is "Engine (DMD or Lamp) Fan failure". Error code 1 3 is "DMD or Lamp Fan Stopped"
I was thinking maybe it was a fuse. The wires for the DMD fan and the Lamp fan travel together and plug into the same plug on the power supply board.
I am so disappointed. I've struggled with this TV for months. Finally got it working beautifully, only to have this happen. I don't know what could have happened carrying it outside and into the family room. Can somebody help me out with what to look for to fix this issue? Thanks

ERROR CODES
Press and Hold "DEVICE" and "MENU" FOR 5 SECONDS
3. 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.

The Error Code
I already know all that. I had in my post what error code 37 was. I am trying to find out what could have broken from the time I had it in my basement to when I brought it into my family room. Thanks for the reply though.
