SOURCE: green blinking light
This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source)

My thanks to your husband (and all who are involved in this stupid conflict) for his service.
You didn't mention whether there was a pattern to the blinking which in some sets can be decoded into a specific problem. I'll assume it is a regular blink rate you have.
All modern sets have a standby state that allows them to respond to the remote when they are 'off.' The power for the LED that's blinking comes from this 'always on' power supply and the fact that it is blinking probably (and unfortunately) means that either the main power supply has failed or possibly the lamp in some brands.
Because this can come from more than one place, it's not possible to determine which source it might be. The owner's manual might give info under 'Troubleshooting' as to the source.
If you don't have the manual available, you can download one here:
If you find that it is the main power supply, this is likely on a separate board and may be user replaceable.
Pull the AC plug from the wall and let it sit for at least a couple of hours to allow certain components to loose any dangerous charge. Remove the lower panel from the set and look for a board with larger than average parts on it, particularly cylindrical objects (capacitors) and larger dark blocks (transformers). Look on that board for a part number for the board (not the components).
Locate the nearest Mitsubishi repair company and call to see if they repair failed boards or only sell new. Once you have the price for it (could be $90-$200 US), you can decide if you want to replace or repair it.
Replacing the board is probably not rocket science and have had several ladies do this on their own.
If you find it is the lamp that has failed, this is also something you can do without great technical skills and the prices for these ranges from ~$125 - $200.

This set has a lot of problems but I have news for you that I recently discovered from a authorized Mitsubishi repair center---
Mitsubishi has had so many problems with this set that now they sell a complete Chassis replacement for this set for about 200 dollars--You will have to go to a authorized center---no more trying to fix individual boards in this set...if you are in doubt--Google the model number and you will see all the problems this set has had---
Contact Mitsubishi and I think the best thing you can do is get the Chassis replaced--
If you have more questions about what I am telling you let me know---I think Mitsubishi is trying to avoid the class action lawsuits that are in progress against them for this model.
REGARDS, SD TECH

Testimonial: "Thanks for the tip. I left it blinking for 2 hours and tried reset again and it worked. But next time i'll use your tip to find the prob."
SOURCE: TV won't turn on
If the led is blinking one time there is a problem in the 140 volt circuit. Most likely a shorted Horizontal Output Transistor or a bad flyback transformer.
I would recommend that you contact a local servicer in your area and see if they can come to your house and diagnose the problem and give you an esimate for the repair. This can be tricky to diagnose and the potential for electrical shock is very high. So I would be careful if you wish to repair it yourself.
I would guess that you should be able to get a servicer to your home and repair the set for somewhere between $350.00 - $450.00 depending on the parts that are needed and the area in which you live.
I hope that this helps you with this issue. If you have any further questions, please post and I will try to help you as much as I can.
Thanks for using FixYa
