Re: mitsubishi projection tv vs60va2 picture rolls
This unit has chroin bad caps on the 5v, 9v and 12v regulators. If you know circuitry you can check thos caps and replace the weak or open electrolytic caps. If you call on a tech that services mitsu. this is faily common repair for them and should not cost over 150.00 to 200.00 depending on your area.

I think that means your FMT brd is going out. you can have a mitsubishi authorized service center come out and send an estimate to mitsubishi for help on the repair, or have a service center come out and repair it, usually about 300-500 out of pocket either way
A rolling picture or loss of vertical sync can be caused by several components including a bad signal board or jack panel assy. You will not be able to resolve this yourself. contact a Mitsubishi authorized service center.
I have seen this many times. There is a 9 volt regulator on the small signal board that causes this. The regulator goes bad and the 9 volts starts dropping, especially at start-up when the regulator is cold. If the voltage is below 8 volts then the picture gets dark and the vertical becomes unstable, with the picture squeezing down and/or rolling. As the regulator warms up the voltage starts rising back towards 9 volts and the symptoms start clearing up. There are 3 regulators in a row on the board and the regulator in the middle is always the bad one. Replacing that regulator should cure your problems but it should be replaced by someone experienced in servicing Mitsubishi projection TV's because pulling the chassis out is quite tricky.
