I do not know if you can see: in the top of the screen there is a yellow band. It is not a problem with the tubes or the sources because the band appear in all tubes. It has also changed the cable. What could cause this effect? The owner of this projector is a friend of mine.  |

Are you able to swap boards? I would try the vertical board first.

When you made that picture, is that the internal white pattern or is this an external?
If its not the internal pattern, can you check that?
If you go to random access > genlock pattern > go to picture tuning > colour balance > select colour, and see which colours it is affecting, if indeed it is affecting the internal pattern.

The picture show a 100% white pattern from VP50 videoprocessor.
He tried to connect a laptop with a stock vga cable (from pc's monitor) and a port 3 adapter cable.

Perhaps it's important to report another strange issue.
If he start the warmup routine, the pattern appear strongly pulsating and the eht's red led blinking.

Well thats not a good sign, when my Barco did that it was a quad on the way out. With a bad quad, i have seen some sort of interference in that area of the screen, affects all 3 tubes evenly, and will affect internal patterns the same as source. |
