36" Mitsubishi tv rolls

Put it back to the mid point of it's adjustment range.

If the V hold won't stop the picture rolling at some point in its adjustment range then the circuit that it affects has drifted out of tolerance. The defective parts in that circuit need to be replaced.

This TV needs a service adjustment done. Looks like a vertical or horizontal IC is failing. I'd go ahead, and shut off until services adjustment is made. Have you unplugged for a few minutes and plugged back in? However, I'd have a service tech look at it.

That is the camera not being in sync with the refresh rate of the TV. With consumer gear, there is really not much you can do about it.

II NEED TO RESOLVE A PROBLEM OF VERTICAL SINCRONICE I SALLBE GRETFULL TO HAVE ADJUSTMENT INFORMATION I SHALL BE GRATEFULL IF YOU COULD HELP ME

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.

Look on the back and see if you have an adjuster.(It should say
H-HOLD) Just turn it very slowly until the picture stops rolling,You can do this by watching the tv screen in a mirror.

Please rate this solution.

my screen on my mitsubishi won't stop rolling

yes it can be fixed depending on your model number if its the VS50605 they have a kit to repair the PIP module which controls vertical sync (Rolling) or you can bypass the module to correct it but you would lose the PIP function. Let me know if you need more info.

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.
