When the projector warms up the picture starts to roll intermitently.

The problem looks like a mainboard problem if you have checked all the cable connections going from your source to the projector.If you are yet to confirm the cables, then u should try to check the connections by putting a spare VGA / video cable

how may hours has your lamp done?
if you have crossed more than 1500 hours , u may need to change the lamp.
the problem could however be that of the signal cable which could be intermittent and causing similar fault.
check if the same problem is seen in all inputs!

seems you burned one line actually A output i would say even input but you have to check line a

first of all open the projector and clean it form a bursh then cheack a losing if stips and jumpers thats it

If possible, try to replace the VGA cable between the projector and the computer. A bent or broken pin, or a damaged wire, can prevent the blue or green (or both) portions of the picture from being displayed. The result is a reddish/pinkish picture.

As for the long time to project an image, this could be an extended warm-up time. How old is the bulb in the projector? Does the projector have an option to display the hours used and/or remaining on the bulb? Bulbs do have a finite life, and when they near the end of their service life, they can become more difficult to start.

Hope this helps!

A number of this type of JVC projectors had issues with defective soldering to a large capacitor on the pc board in the power supply which could cause such an intermittent prob. Some models also had a similar issue, but one lead of the capacitor was actually broken when inserted at the factory. You would need a tech to look at this, unless you are capable.

bang on the starter, see if that helps ..also check all your grounds

Have you tested the source machine on another TV or projector. The picture might be rolling before it gets to the projector so you need to verify whether it is the source machine or the content then you might be able to determine if it is the actual projector. Sounds like the vertical sync has got lost somewhere.
Hope that helps. Also we can supply lamps for this model if you ever need.
Re your Sharp XV 9000S We are able to supply replacement lamp+housing delivered (excluding local your local taxes) for $US342 as we ship internationally and also the same with our revolutionary ICE Digital Daytime projection screens.

Hi Ian

Your Projector is in need of a new Mainboard.

Must warn you that it could be a costly exercise

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.
