You'll recall helping me with the solution to my mitsubishi wd52725 and the power board..i replaced the eight caps and the set powered up and ran with no problems until yesterday...i was watching the news and suddenly the screen went dark and the yellow led started flashing. after about forty five seconds it changed to the green led which flashed very fast.
i tried the reset, no help. i tried to get a code, could not..so i unpluged the set for five minutes and it came back on...i watched the rest of the news and turned the set off (everything normal).this am the green led was flashing again. unpluged set and it came back..watched for about thirty minutes and it shut down again..yellow led flashing followed by the green led. after the green led flashed for about thirty seconds the yellow led flashed 10 or 11 times , then back to the green. this repeated once more and i have unpluged the set. any help you can offer again?

Once you take the shield assembly off, you will see a board, I believe it is the DM Board board. There are four Capacitors grouped together probably rated at 35v 1000 mfd, 105 degree. They should be replaced with 35v 680mfd,105 degree Capacitors. Now once that is done, there is another board under that one. This is the Format Board. It also has 4 Capacitors that should also be replaced. They are the same value as the first Board and should be replaced with the same 35v 680mfd, 105 degree Capacitors.
Please note the Flex connectors at the bottom of the DM and Format Boards. They may not be available from Mitsubishi any more so be gentle with them and make sure the are installed properly when reinstalling the Boards back into the chassis. There is one other Board you should look at. The Power Supply Board is the board on the back of the chassis and also has a number of Capacitors that fail. Most all of the Capacitors that fail through out this chassis will have bulging tops. So any you see bulging, you should replace whether they are on the DM, Format , or Power Supply.
I hope this helps,
The E2P module need replaced. If it is not available you need to send it to Mitsubishi to be reloaded. It is a small 3/4 inch by 1 inch board that plugs into the main board in thr depths of the chassi. It's actually an Eprom and the firmware get corrupted and has the be redone.
I would causion removing the DM board in this unit. It is buried and the real problem is that there is many capasitors across all the boards of the chassi assy that could go bad. Replacing the ones on the DM will not guarantee fixing the dreadful green Blinking
LED. The only way I have known it to be fixed properly is to actually send the chassi assy. to Mitsubishi for them to refurb it. The negitive thing is that it is exspensive and they will only refurb it through aAuthorized Misubishi Repair Facility.
Cost would probly be around 800.00 to 900.00.
I know it is not what you wanted to hear,
but that is mt take on it.
Hope this helps,
But it is the
Haven't done anything as of yet. I saw many posts that stated it costs between 800 & 1500 to fix the problem with no guarantees on the repair or how long the repair would last. Still weighing my options.
code 12 means no error detected. However when your lamp wont light and you have replaced the lamp it is usually traced to the cpacitors on the PWB PCB that need replacement. You can get a repair kit for that model at the following link. Its called the V26 PWB PCB repair kit. which contains all the capacitors and a CD with the capacitor board locations and disassembly instructions and board Identification and full Service manual for that model DLP. Heres the link. http://servicemanuals.vstore.ca/
