i have a WG4900 in my q*bert which has had a video problem since purchase. it has some lines up and down the display (starting very closely spaced together on the left-hand side of the screen, then spacing out to about 1.5 inches between them across the rest, canted slightly to the right as they go down). i took out the monitor and the vertical section of the chassis had some burning, which makes sense as the monitor is rotated so those lines are because of something misbehaving in the VOUT part of the chassis. i re-capped it hoping that would do the trick, but it didn't.
so i can do some more testing on the chassis that is in there (riptor pointed me to testing the solders on the wire-wound resistors, for instance), but i have a 2nd chassis and i'd like to try it in there instead just to see if it might work.
i have two questions about this:
1 - the old neck board is attached to the tube with some white glue-type stuff. i've attached a picture with it circled. what is the best way to get this gunk off? i don't want to damage either the tube or neck board while removing the old neck board of course.
2 - i'm wondering what to do about the grounding strap. it's a bit of a pain since it's soldered on to the corner of the neck board. should i solder it off of the neck board in there now and re-solder it to the potential replacement neck board, or should i leave the strap on the replacement and run it around the tube?
thanks in advance.
