[Cine 7] shaking picture

post #1 of 10
Thread Starter 
Hi,

I just did a rough setup on my Cine 7 (with 694 hours) to get familiar with the controls. It's bin a few years since I last worked with crt projectors.
I already got a pretty nice image but also some problems:

The image is continuously moving/shaking. Like someone is zooming in and out a tiny bit, constantly. The convergence stays intact.
When I look into the lenses I see on the bottom of the Phosphor some rapidly moving lines. On all the tubes. These lines don't dissapear when I use blanking. The lines look somewhat like this:



The Barco is hooked up via component on my TViX which is configured for 1080i/60hz. I tried different resolutions but the problem stays. I tried lowering the contrast and/or brightness but the problem stays.

It doesn't matter if I use a external source or a internal test pattern. The problems are the same.

Does this sound familiar to somebody?

Edit: I just tried deleting all memory blocks and set everything to mid positions. It didn't solve the problem.

HV problem most likely

It is indeed a HV instabiliy problem. I made two videos. One of the problem (don't mind the music ), the second one of the noise the quadrupler makes. Is this noise normal?





If the quadrupler is the culprit, where do I find a spare one?

Whoopsie. Posted that with the temporary account I created when I couldn't find all my other account data. How can I remove that account?

While it could be the quad, I don't think so.
