Happy New Year and thanks for helping everybody out. I also have the dreaded green blinking light on my 65 mitsubishi. Could you please e-mail me the instructions on replacing the capacitors. e-mail to [email protected]
I finally got my TV to work but changing the Capacitors and Thermal sensor didn't do the trick. I figured out the whole problem after reading a Mitsubishi tech manual.
The Problem:
Mits DLP TV has two microprocessors, PC and DM, that communicate with each other. Normally when the TV powers up the DM processor is waiting for a request from the PC processor and communication is established. After a power surge, the boards may lose communication with each other. Each processor sends out a request and waits for a response from the other processor, bad idea. The problem is each board is waiting for a response at the same time. Microprocessors can't receive a request when it sending a request. So either processor get the request cause they both sending out a request at the same time then listen at the same time. If the processors don't get a response, they reset each other, even worse idea. The reset put the processors right back where they started. This is why the front reset button does not work. THE MICROPROCESSORS HAVE A TIMING CYCLE PROBLEM WHICH IS COMMON IN DIGITAL CIRCUITS AFTER A POWER SURGE OR BAD SHUTDOWN, WHICH IS WHY THIS AFFECTS SO MANY DIFFERENT MODELS. Mitsubishi should of never allowed both microprocessors the ability to reset the other. Only one processor should be able to reset the other and the other processor should always be waiting for a request after communication loss.
The Solution:
1. Power the TV on and wait for the blinking green light to stop.
2. Press input and menu at the same time and make sure you have error code 12
If you don't get this error code you have a different problem.
3. Press all the front panel buttons on the TV one at a time, except the reset button and power button.
This sends a system command to one of the processors and interrupts the processors from waiting for a response. After the processor is done with the system command request, it sends a request to the other processor that is waiting.
4. Hit the power button on the TV and it should fire up.
If it doesn't work repeat step 3 and 4 several times. When the processor was done with the system command request, it sent a request to the other processor but the other processor was sending a request too. The trick is to get the processors off the same timing pattern. If after several times it didn't work you probably need to replace the caps since the power surge burned them out.
Misc:
Some people change their caps and get the TV to work and some don't. The microprocessors continue to be hung up after you unplug the TV because the caps act as batteries. The microprocessors still have a timing problem because the processors never stop working. These microprocessors are low power which means these caps can keep them powered up for days. This is why some people get their TV to work after days of sitting in the corner, unplugged. If you remove good caps from the DM board, the TV might fire up because you removed the processors power supply on the DM board and they are on the correct timing cycle after you changed them.
If you have a power surge and it burns out your caps you get the blinking green light of death. If it didn't burn them out, then you get a timing problem and you get the same blinking green light of death. Therefore, the blinking green light of death can be cause by a timing problem or bad caps or both.
FYI:
Put the TV in low energy mode. This allows the DM processor to shut off when the TV is off. During power up, the DM processor has to wait for a signal from the PC processor. After a power surge, the processors won't care if they lost communication cause the DM processor has to power up from scratch and wait for the PC processor. This should fix any future blinking green light of death.
I need a Mitsubishi tech manual.can you help please I have a ws-65517 I don't know the caps to replace I'm disable and can't aford someone to fix my tv I need help I have repaired radios in the service so I can change out parts.I need help on knolage on the tv and problems that can couse the blinking light thanks
Larry I seem to be having the same problem as alot of people with the Mitsubishi WS 65513 flashing green light. I have tried resetting several times and even leaving it alone for a week and it still want quit blinking. I noticed you talking about fixes for this and some kind of instructions. Can you please send it to me. My email is [email protected]

Would you have any information on setting the convergence. I have a consumer electronics technician background (although it has been a while) and have experience doing convergence on projection sets. I also have a test pattern generator with crosshatch pattern. Does this set have a board with convergence controls or is it done electronically? If electronically, how do i access the programming?

Larry,
I have a WS-65513 and have the blinking green light also. We just had several power outages and now I have this problem. Can you send me a copy of the repair procedure?
Larry,
I have a Mitsubishi WS-65513. We just had several power outages, and now that the power is back on, I have the dreaded blinking green light. Tried unplugging it and resetting it with no luck. Can you please email me the directions.
Thanks,
Louis Smith
We have a 6 year old Mitsubishi WS55511 that has the famous green blinking light after a power outage. Tried the unplugging and resetting and were unsuccessful. Now we'd like to try the repair you have the instructions for. Could you please send it to: [email protected] Thank you so much.
Larry i talked to mitsubishi tech and they were no help i then say the e-mail regarding the cold wether and i started to wonder what would hapen if i heated up the the tv. I heated up the box in the back of the tv where the capacitors are and after the box was hot the tv came on and it has been working ever sence.

Thanks

Same problem - is it still possible to get the instructions emailed to me? tkx in advance...!!!
Hi Larry, do you have instructions to replace those bad convergence IC's
Larry
Another casulty. Can you email your repair for the capacitors @ [email protected]
thanks
jack
I have the same problem wit the blinking green light. Can you email the fix-it repair manual?
thanbks
jack
I did the capacitor change out, but still have the blinking light. It was worth a try though.
