Another problem with my 52725

The DM boards for that chassis are almost impossible to find if they are still good. Have you tried replacing the caps on the DM board that you have? Thats usually whats wrong are bad caps.

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,

Thats caused by failed capacitors on the DM board. You can get the V26 DM repair kit at www.tvrepairworld.com which should fix that issue. The kit contains the capcitors and the CD with detailed repair instructions.

These sets had a lot of problems like yours---for a while lots of them had 3 different boards with caps going bad etc---a real nightmare---fix one board and a few months later another goes out.

I was at a local Mitsubishi authorized repair center recently---Because of all the problems there is now available an ENTIRE CHASSIS exchange for most of these sets---it wholesales for about 200---a third of what it will cost you to have a shop fix all three of the suspect boards.

This is from what I was told a response by Mitsubishi from the THOUSANDS OF ANGRY PEOPLE WHO PAID A LOT OF MONEY--and 3 or 4 years later the sets are dropping like flies.

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.

You need the V26 power board repair kit. You can get it at the following link and it comes with step by step instructions with pictures. Heres a link to the proper kit.

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.

Good Day;

Sounds like you may have a bad Format Board.

Good Luck, big IRISH.

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.
