Title: help repairing a 25k7191
Post by: abzman2000 on April 16, 2009, 03:34:37 pm

I picked this up off of craigslist and haven't tested it yet, before I do I want to make sure I don't damage it more than it already is.  so far I think I need to plug the degaussing coil back in, add a power plug (hooked up through an isolating transformer), get a new pot for the control board and clean up the solder on those odd home-made ground jumpers.  is there anything I missed, and anything you can tell me about this monitor or how best to deal with some of the problems would be helpful. 

edit: also, what is that strange board that isn't attatched to anything?
