Re: Blinking Green LED
Good Day, lellis361;
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.

Hi, If the led light flashes green continuously, the fault came from the DM power supply. The faulty parts there are the electrolytic capacitors. Let me know if your handy with electronics and I will assist you to fix it yourself.
First thing to do is remove front speaker grill--it should pull out and issecured with plastic pegs--behind it you will find an inspection plate---
Notice the one or two pairs of wires coming from the front keyboard of theset---remove the inspection plate and follow the wires to the right--you canunplug both plugs(most have two and they are marked with letters and differents so you cannot get them wrong)
The idea here is to remove the front keyboard with its reset button etc fromthe circuit---You will still be able to try to turn the set on with theremote---
These sets have a Receiver that is called a DM board--(large metal box to theleft as you look from the back) and if the power goes out the green light willblink for about 70 seconds and then go out---it is the Receiver booting up. Itis called the DM board.
If disconnecting the keyboard allows the set to turn on--you have a bad resetswitch and two choices---either operate the set only with the remote or toremove the front screen and get at the reset switch (it is tiny) and removeand/or replace it.
If disconnecting the keyboard does not restore the set to operation---thereceiver is bad---there are 4 or more caps and some pico fuses that can fail inthat unit---Mitsubishi no longer sells or repairs these--if it is bad and notthe caps there is a company you can send the unit to and have it repaired--ifyou need to know their name let me know---
You can call them and get a quote for repairing the receiver.
Let me know what more information you need--I am here to help.
First: the blinking green light means the set has a DM unit in it. It should when unplugged and plugged back in blink for 70 seconds and then go out.
One of two things is wrong here:
1) The DM unit (large metal box on the left as you look from the back) has several capacitors and fuses that can fail.
2) Try this: Pull front speaker grill off: held on with plastic pegs.
Remove the inspection plate you will find in back of it.
Note the two groups of wires that come from the front keyboard; follow them down and to the right and unplug the two plugs you find; most have two and they are different sizes and marked so you cannot get them wrong.
The idea here is to disconnect the entire front keyboard and the reset switch from the set.
You can still turn the set on with the remote.
If the set now works--you have two choices----use the set with a remote and the keyboard not connected.
Remove the entire screen assembly and remove and or replace the reset switch.
IF DISCONNECTING THE KEY BOARD DOES NOT CURE IT--the Dm unit is bad---either change the four caps--lots of sites sell kits for this OR send the entire DM unit out for repair/rebuild to someone like PTS ELECTRONICS.
THE BLINKING GREEN LIGHT IS THE DM UNIT TRYING TO BOOT UP--LIKE A COMPUTER.

how long was it blinking. after a complete loss of power the green light will blink on power up as it is resetting itself. It says in the manual that it should take about a minute. Over the last two days I've have to reset it several time both by unplugging it and using the manual reset button and it has taken about five minutes for the blinking green light to clear.
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. http://servicemanuals.vstore.ca/
