Blinking green 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.

the green light blinking is normal if set has been unplugged--when set is plugged back it should blink for about 70 seconds and then go out--then you can try to turn it on---it is the DM unit inside the set booting up.

If the light just blinks and never stops you have likely bad caps in the DM unit---there are kits available for that.

The other possible reason is that so called reset switch may be bad--fairly easy way to find that out and it is more common than you would think, let me know if you have questions.

SD TECH

I found this on another website, most likely it is your power supply capacitors.

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.

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

when the green blinking light won't stop you have a bad dm module, it's about $800 just for the part. you could take it apart and try changing the big 1000 micrfarad at 16v capacitors on the dm board, but this almost never works on dlp's, and taking this tv apart to fix it is a major job, you need alot of money and a tv repairman to fix this.

You are not going to like this one little bit. The reason the LED won't stop blinking is because the digital module is not booting up. I have been fighting this model Mitsubishi for over five years now and the only solid fix is to send the entire chassis back to Mitsubishi for rebuilding. Pulling the chassis is a major job and with shipping costs and Mitsubishi's charges this repair usually runs around $750 to $850. However many owners that contacted Mitsubishi about this problem have gotten that portion of the repair bill coverd. That still leaves $300 to $400 for the tv shop that pulls the chassis and reinstalls it once it is rebuilt.

Replace all 7 capacitors in the DM Module on the DM Power Supply Board. If it is similar to the WS-65869 and WS-65513 it will have a metal enclosed DM Module at far left of chassis, looking from rear. About 4 or 5 connectors, screws, and Module slides out. Take top shield off. Take good notes or use digital camera or video recorder to make re-assembly easy. These capacitors are 1000uf@16 volts. They always check good, just replace them! After re-assembly plug AC in and wait 90 seconds or more (green Timer LED will stop blinking), then press Power button. If Timer LED doesn't stop, look for small pinhole (System Reset) and press switch with pen or small screwdriver, then wait for green LED to stop blinking. Then Power On TV.

this tv is mitsubichi?
is mit what is the model?
look like bad DM, you need chage The capacitors.

bad capacitors 1000uf on the PWB, FMT and DM boards will cause those symptoms. All capacitors 9 in all need to be replaced

Try doing the self test by pressing input/device and menu for 5 sec. You should get an error code by blinks. see ctechnicians.com
