Title: 19K7201 foldover - need quick fix (man this monitor is a pain in the ass...)
Post by: Mauzy on October 24, 2008, 09:09:00 pm
So my 19K7201 that has been the topic of two or three topics since I got it about 2 years ago suddenly has a bit of foldover (I think its foldover. About an inch long bar is skewed at what, if oriented horizontally, would be the top.) Its currently mounted vertically. Ive messed with both holds and the 50/60 hz and can't get the bar to go away. Ive even re-wired my harness, but nothing. I am almost sure this is a cap issue and I will get a cap kit asap, but I have company staying for a couple days coming in a couple days, way before I could get a cap kit and have it installed. Does anyone know what cap(s) or how to find the failing caps so I could at least make it look good?

No domed caps can be seen and nothing crazy (voltages, bumps, etc.) has happened to the monitor or cab.

Wells Gardners website lists a few possible causes of vertical foldover in their troubleshooting guide of this model.

This problem is usually caused by bad electrolytic capacitors.

I figured it was the caps. According to that it could be C50 or C48. Ill hopefully pick those up tomorrow and see what happens. Thanks for the link!

Great. Took out the chassis and found that most of the cap location markings are covered with the support glue. Who ever did that was real swift...  :angry:
