this is a best buy exclusive from 02 that the manufacturer assigned this model number to. it is similar to the ws65315, ws65415 projection tv's.

the chassis is a mitsubishi v20b. the tv flashs or blinks between a clear picture and a black screen. the black screen lasts for a fraction of a second before the picture reappears. the tv flashes as many as 40 times a minute. there can be as several seconds between the flashes or it can flash a little faster than once a second. the fault appeared 9 days ago and has occurred about half the time the tv has been on.

I'd suspect your convergence IC's.

I have the same TV that started doing this in March-09. My set was also from BestBuy. Good news is I had an extended warranty on it. Bad news is I have had 9 different techs look at it and none can figure out why. They have replaced all three PBC boards as well as the PWB-CRT that is the power cords for tubes. It still doing it. All that's left is to replace the tubes, which Geek Squad is fighting with me about.

Anyone else having these isues ?

I repaired a Mitsubishi US-363RS about 3 months ago,that was flashing off and on.I replaced the convergence ICs and resoldered the whole convergence board.Mitsubishi boards always have bad solder,even the brand new ones.
