Question about Mitsubishi Televison & Video
Yes, Mitsubishi can be very good about compensation on OOWproblems that are repetitieve and catastrophic. You need to be communicatingwith consumer relations and you need to be diligent and patient. My experienceis that in the end, Mits takes care of their customers better than most, evenif the process is clumsy and at times very frustrating.
This can be a more complicated problem than just changing the DM. There areseveral things going on in this chassis that we have not yet figured out. Ijust had one of this model that we did the following on:
Changed the bulging caps on the DM.
Changed the DM per Mitsubishi instructions.
Changed the EEPROM.
Changed the bulging caps on 4 boards in the set.
Changed the reset ICs
Changed the Signal Board.
After none of this worked the soloution was to replace the entire chassis,which came in defective with a bad EEPROM. Mitsubishi paid for the parts.
Unfortunately, Mits is not supporting component level repair on these boardsand we have only limited block diagrams for some circuits, not completeschematics. This means that we are not able to figure out exactly what isfailing and troubleshoot the sets very effectively. Additionally, they don'thave enough of the boards and the chassis is on backorder. They won't tell uswhat they are doing to fix them, so we are largely stuck waiting for expensiveparts like an entire chassis. Mits is eating parts and in some cases labor whenwe could be field repairing them much more effectively if we just hadschemaitcs and some info. Stupid, short-sighted policies, IMO.
Keep calling customer relations, get file numbers, get tech log numbers fromyour servicer for any communication they have with Tech Support at Mitsubishi,get everyone's name that you talk to and keep good notes. Like I said, withpatience and diligence, you can likely get some accomodation from Mitsubishi.How long the fix will last is uncertain.
Also, be sure that you are using the coaxial line protection on your surgeprotector, and be sure that your in coming lines are grounded according toelectrical codes.
Re: Mitsubishi WD-52825 Blinking Status Light:
The first thing to do is a system reset using the recessedbutton on the front panel.
>>If that does not work, unplug the set and let it sit overnight.
>>If it still does not come up .Here's something that might also beuseful. After you turn on the set, and get the regular red blinky lights, holddown the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

It is common for a cuircit board called the dm(digital module) to go bad in these units. this set has a keyboard lockout feature.
Press menu for 10 seconds on front panel. if that does not release control then u more than likely have a problem with dm module. there are several bullitens about this and several things a tech can do to repair this set.
just a head's up, getting this repaied my cost a little big.

You may need to change the convergence IC. First go into the power supply and check F9A04 and F9A05. If anyone of these are bad, do not replace them. Replace the convergence IC and then replace the blown fuse. Replacing the fuses without replaceing the IC first could result in more damage to your power supply.
Hope that helps.........
