Hey! Just finished recapping my Weiya 2628HR. First time doing this so really happy its all working. I also changed the hor.width cap to narrow the image a bit which worked well.
Need help troubleshooting the next issue: there are 9 adjustment pots (on a separate board). 7 of them work fine. However the pincushion adjustment and the hor.width adjustment don't do anything.
I've checked the pots themselves and they're fine. I also tried a spare adjustment board and get the same issue. So it doesn't seem to be caused by the pots themselves.
I also measured the voltage input/output of the pots against ground when operational. While with other pots the voltage increases/decreases as the pot is turned, in the case of the two malfuctioning ones the voltage doesn't change (but note that when measuring the resistance of the pots, the resistance does change as expected).
Note that this issue existed before recapping and hasn't improved since recapping.
Could there be one common issue affecting both adjustments? Or am I looking at two separate things?
Thanks!
