Blinking gren light

This is a V19 chassis, circa 2002

If all capacitors were replaced correctly & all caps with bulging tops were replaced, It sounds like you may have other issues on the DM pcb. Possibly defective ICs. That would be the E2P module (a small pcb which plugs directly onto the DM pcb), which is specific to your particular model & serial#

Several years ago the only way to get the E2P, was thru the manufacturer, they also, used to make a kit that you could replace those ICs yourself. Those pcbs & kits were limited. So all I can do is wish you much luck if that is the problem.


At this point I would double & triple check the replacement of your capacitors.

Hi,
You need pictorial to locate dm module in tv and to replace bad capacitors.
This Link will help you to locate dm module in tv and info about what are requirements to replace bad capacitors in dm board.
Hope this will help you.
Thanks.

hi friend,
Repairing It Yourself
If you decide to repair the TV yourself, I recommend that you obtain a copy of the repair manual for your Mitsubishi TV from the Techlore website by going to Mitsubishi Service Manual. It will provide some direction, however it is technically written and may be difficult for the NOVICE to understand. If you are unable to locate the the service manual for your specific Model at the above Techlore link, you may need to purchase the service manual online at ServiceManuals.net.
If you decide to have a service technician do the repair, insist that the "DM" module is removed from the TV and ONLY the four 1000uF, 16V Capacitors (Caps) located on the DM Module are replaced. MOST techincians will INSIST on replacing the entire DM Module and not simply the capacitors. The cost is about $200 for a technician to replace the capacitors and $1000 for replacement of the DM Module. As you will read below, doing the repair yourself will cost less than $4.00 for the 4 Caps.
A Few "Cautions"

1. Keep yourself "grounded" when working with the circuit board. Static electricity will destroy electronic components.
   
2. When replacing the Capacitors, press them "down" onto the circuit board as far as they will go, hold them down, solder into place and clip the excess terminal lengths flush with solder. Only by doing this will the metal shield (little silver box) slide down and over the circuit board during re-assembly. There is not a lot of clearance when doing this, as the 105C Capacitors are slightly longer that the originals. With minimal effort everything does fit back together.
   
3. Use ONLY 105º C capacitors with a voltage rating of 35 V.
   
4. Re-insert the DM circuit board into the Mother board; press virmly and ensure a proper seat of the DM board. Next, slide the metal case down and over the DM circuit board. Refer to my "Lesson Learned."

Basic Troubleshooting

1. Press the "reset" button and hold for 10 seconds .... Does TV turn on and blinking green light turn to solid green.
   
2. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours..... Does blinking green light continue upon plugging in the TV.
   
3. Disconnect ALL devices from the TV; DVD, Tuner, Cable Box, unplug the TV for various duration times .... Does blinking green light continues upon plugging in the TV.
   
4. Press Power and Menu buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.
   
5. Press Power and Display buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.
   
6. Insure that no front panel buttons are inadvertently stuck in an "engaged" position.

Diagnosis: If none of the above test resolve the issue, then the failure lies in one of the following:

1. DM Module Capacitors have FAILED.
2. DM Module is defective.
3. EEPROM Board failure
4. Power Supply failure.

hope this helps u
please rate me.....................
thank u for using fixya

the common fix for the " mitsubishi blinking green light of death " on this model is replacement of electrolytic capacitors on the "DM module board"

Hi,
Check this link for guidance with pictures about DM board removal.
Thank you.

You can get the V23 DM repair kit at the following link which has the replacement capacitors and the instalation instructions on Cd which has pictures of the repair. Its listed under the repair kit category.

Good Day, charliek1;
This a very common problem with model. Don't listen to other comments unless the use the correct replacement parts.

SYMPTOM: Power LED does not stop blinking after plug in.

CURE: replace C9B01, C9B02,C9B10, and C9B11 (1000 uFD 16V) on the DM PCB. Replace them with part # 181P734030 (680uFd 16V).

The DM Board (PCB) is located on the very left side of the TV looking from back. Caution on removing Board and note what cables you disconnect to access the Metal Shielded Board.
Good Luck, big IRISH.

The four cap replacement in DM module repair is simplistic
and incomplete, as you found out. ALL defective DM modules
have bad SMC's ( small "top hat" caps) AKA surface-mount
capacitors that can be changed only by the most highly skilled
bench techs. We used to change out hundreds years ago in
camcorder circuit board repair.DM board repair is a much more
accessible,thus more "do-able". For more info.............T.

This part will cost you about 650 to 800 bucks my friend. if you have any soldering skills, and can follow directions, I posted a DM board fix. it may just be four small capacitors. Now this set that was used in the fix is not exactly like all the other Mitsubishi TV sets that still have a DM board, but if you can locate the DM board, follow the rest of the repair. if you do not know how to solder, do not take a chance, as this part is way too expensive to be experimenting around with. Get the Capcitors(there is a link there too for the capacitors)and take the DM board to a service shop, as this should not cost you a lot to have a pro do this for you.
