Hi
Since I bought new 8liners chassis to my Hantarex Polo 25" tube, the h-pos pot isn't working properly. When I try to adjust it, the image "jumps" from one side to the other. There is also a screen jittering. It can be noticed only when very very close to the screen, but it's present.
After a 4 months of usage, a new isse have arrived. After A few hours since I turn my machine on (I've got MK2 cabinet converted to mame and using soft15khz) there is this "click" sound and the image is a little wider vertical and darker than before the "click". I think it's something with high voltage, however B+ seems to be fine.
Here is the video:
Please help, if you can.
