This is called the blinking light of death in these sets---when power is removed from set and put back the light should blink for about 70 seconds and stop----it is the digital signal unit booting up.

About the only common easy failure for this is there are 4 caps on the power supply board that fail---they will be puffed up on top like photo attached.

Blinking green light on Mitsubishi will not turn off


The capacitors on the DM board need replacement, thats a common problem it will work fine but if power is loss even for a minute the capacitor drain, then they cant recharge since they need replacement so the set will just keep blinking the timer light. Installing the V26 DM repair kit from www.tvrepairworld.com will usually repair that. The kit contains the Replacement caps and the CD with detailed instructions.

Tv cuts off and green light flashes


If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

Good luck!

Tv cuts off and green light flashes


Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.
Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!
