Anyone know why my WG4600 has a slight horizontal flag, or roll. It is so slight, a pic or vid would not even pick it up. Just wondering if its normal or not, this is only the second arcade I've owned, my first has an XY monitor. I cannot adjust it out either.
This is what I did when I rebuilt it:
Every CAP replaced, even the large 1600V.
New HOT transistor and the transistor on the opposite side. B+ voltage is where it should be too.
New .156 terminals, coming from the board, going to the male terminals on the one daughter board.
Fixed any grounds whose wires were brittle at either ends.
Checked the big red yoke wire, going to the flyback for looseness.
Reflowed solder to every single solder joint on all three boards.
I did the humm bar mod, where you place sheet metal over the transformers, found on Roberts site. This did nothing...
I searched the site and found to adjust the metal silver square, with a slot for a reg screw driver, found on the vert/hor daughter card. I just did this and all it did was distort the vertical it seemed on the right side.
I also put all new CAPS on the main board PCB's and the game has all its proper yellow ground straps.
So now I have no idea, unless I'm being too picky here, the pic looks great, nice vibrant colors. The monitor was degaussed and rejuvinated too.
Any ideas what could cause a slight roll/flag?
Thanks,
