Mitsubishi TV picture rolling

The rolling is a bad filter capacitor on the signal board in the set---Any Mitsubishi dealer can look the model up and see known faults including this one---some of the sets when cold---vertical jitter in picture or just menu---If the menu is stable you have a tiny bad cap= weak caps when cold act up and when get hot regain capacitance and start to work.

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 know this is an old thread, but I would like to post this information in the hope that someone will find it useful.
I just finished fixing this problem on my 1994 VS-6061... the problem is the PIP (Picture In Picture) board located on the Power Signal board. The PIP board contains the numbers 530B552. I bypassed the PIP board by following the directions I found at the following link:
http://forum.doityourself.com/entertainment-center-tvs-stereos-vcrs-dvds/130383-mitsubishi-cs-35301-rolling-picture-problem.html
"Plug in a 4.7ufd @ 35v filter cap (+)at pin 5,(-)at pin 11. Plug in a .01ufd(any voltage) between pin 7 and 9. Just plug the caps into the socket, where the PIP board was mounted (they don't need to be soldered). Just don't let the leads from the two capacitors touch, as they cross each other. The 0.01 cap is non-polarity, so either way it plugged is fine. Basically you will bypass y-signal through 4.7u, in pin 5, out pin 11, and bypass c-signal in pin 7, out pin 9 of the PIP socket.”

The bypass requires 2 capacitors: One 4.7ufd @ 35v and one Non-Polar 0.01ufd @ any voltage.
Remove the PIP board, then plug the two capacitors into the socket where the PIP board was mounted: plug the 4.7ufd capacitor with (+)at pin 5,(-)at pin 11 and plug in the non-polar .01ufd capacitor between pins 7 and pin 9.
If there is a ground wire (possibly brown) soldered to one of the tin cases on the PIP board, then you should connect this ground wire to the PIP socket either at pin 2, 4, 6, 8 or 10 which are grounds of the socket.
This PIP board was used in many Mitsubishi televisions and they were plagued with problems...This is why many of these older Mitsubishi televisions had similar problems…
Good luck

I think I'm having the same problem dont knowif its the cale or the TV I have an old one too,gets wavy kinda rolls vertically

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.

Please provide Model # and mo / yr off back of set and I can help you...................T.

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.

Ahh the old rolling picture problem. If this set has a Picture in picture feature, your problem is on the PIP module itself. There is a kit of surface mounted capacitors that need to be replaced If you have some soldering skills you should be able to do this your self, but if you do not, I advise you to get someomne who does as most of these PIP modules are not available any longer. The kit can be purchased from http://www.mcminone.com/search.asp?keyword=Mitsubishi+PIP+kit&btnSubmit.x=6&btnSubmit.y=7 Good Luck

Does you set have PIP (picture in picture)? If it does then the PIP module has a bunch of capacitors that have gone bad (dried out and leaked) causing you to loose vertical sync. Vertical synchronization is what locks your picture keeping it from rolling. Even if you don't have PIP then still you have a vertical sync problem. The set would have to be checked by a tech to find exactly what's happening. Stargazer

is this a horizontal black line going up or down? if yes, this sympton is caused by a trouble in the integrated circuit or in the vertical oscillator circuit. this symptons has 2 variations. one is the intermittent rolling of the picture. this referred to as the "loose vertical hold" the other variations is the continuous upward or downward rolling of the picture
