I have narrowed it down to the HV unit.
What would cause the graphics to jitter/shake. I have a new flyback and caps installed.
Anyone have this problem?
 
Not sure what monitor you have in there but I had a similar problem with my WG6100 and I adjusted the B+ and added a ground to the monitor frame and that fixed it.

Amplifone sorry for that spelling. I could try that. Is the B+ the R7???
 
Hmmm.... failing FBT, failing caps, improper voltage adjustment.....stray/bad wiring.....

I have seen this exact symptom caused by the new Hoveyking FBT's which were failing right out of the box. NICE.......

MC1 could also be at fault. BTW, this mysterious little part will be available shortly.

May be someethign to think about anyways...
i had a vector god tell me and show me what bad big blues looked like..
whole image kinda wiggles side to side like a rocking boat but alot faster...
 
When you say that you've narrowed it down to the HV unit, I assume that means you swapped in a known-good HV unit and the monitor worked without the shakes? Swapping the known-good HV unit out with the "bad" HV unit causes the issue to reoccur?

Just trying to understand how you determined that the HV unit was at fault.

I swapped it into a cab that had no problems and the shakes occured.
what is big blue?
What is MC1?
 
It's not Big Blue, the cab it was tested in has a different Power Brick and the shakes were present. Big Blue in that cab is new and working with the 'other' HV unit.
