Question about Mitsubishi Televison & Video
Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
If blinks continue without any pause, the main board is faulty.

sounds like it has a bad DM assy, or a bad 9v reg ic.
the dm can be repaired, there are 4 capacitors on it that need to be replaced.

Sorry for the late reply I just got up.
From what I understand of your problem it is most likely a blown capacitor or main IC. Unless I can open up the unit and test the IC's and capacitors I can not be really sure which is why I hardly answer questions about TV''s as they are hard to troubleshoot without the unit in front of you. Ive found a site that can help you via a service manual since I could not find the exact service manual for you from my manual book. The site also has the parts that you will need if ever im right and it is the capacitor or IC. As for the IC's by experience is hard to test without an Oscope but you can do it by gradually eliminating the problem, again you will have to refer to the service manual regarding that. By the way the capacitors I mean is the one that goes to the main module as that is what powers the controls for the TV. the green light is just the "pilot light" which means you have power to the TV but the power is not going past the capacitors to the main controls or the main IC. So simply put the problem can be the capacitors (Which is what you check first) if they are ok then look at the IC via using a service manual. You can use a multitester for the capacitor first if they are dead then just change them and you should be ok. Let me know what happens or updates ill reply to them as well.

I've had my Sony KF-50WE610 for approx. 4years now and have just experienced the prob you described (though I didn't think to count the number of red blinks). I called Sony TV technical support (888-772-7669, #3 for TV/digital cameras, #1 for TV, then #1 again I think). They said that if the power/standby light blinks 5x, that means there's something wrong with the lamp driver and service will be required. Needless to say, I better go home and count my red blinks! Good luck, I hope this helps a bit. Have a happy and safe holiday!
