Hey all!
I decided to replace both the B+ filter cap and the STR381 voltage regulator (on the side of the chassis) on my WGK4900 monitor in my Qbert...just hoping to get rid of some minor ripple that was bugging me.
After I did so, the picture became rather wavy (and the ripple remained). I put back the original filter cap, but the problem persisted. I didn't get a chance to replace the original STR381 as I ended up just putting in another chassis I had laying around that worked just fine, but still I wondering why I got the wavy picture?
Changing the STR381 doesn't even involve any soldering so WTF?
I can just put in the original STR I suppose, but any other reasons this would happen? Do I just need to clean the leg contacts for the STR (where it inserts into the side of the chasis)?
