Hey all,
I'm working on this Hantarex monitor. I get this wavy screen. I checked some posts which state that the most common problem for this is too much high voltage. I checked B+ which is supposed to be 130vdc. However, I'm getting 139vdc. It's a bit high and probably causing this hula issue. I tried adjusting the voltage but the adjustment doesn't work at all. I susped BU508 chassis mounted transistor. Can anyone verify if they ever had this issue with the screen being wavy? Anyone ever measure a BU508 to see if it is defective? How do you test this?
Thanks.
