I have a WG4900 that has a horizontal line running across the monitor, about 1 inch thick. It is a horizontal monitor in a Neo GEo. Any help in trouble shooting is greatly appreciated.
Thanks in advance
 
There's a section on the bottom of the board that says which is the vertical deflection area, check the solder joints on those two deflection transistors. Also of course check all the things in that area for cold solder joints. I would guess a resistor or something has opened up in that area, maybe if there's a cap in that a capkit could help too.
 
Yes, the vertical section is well-known for having many cold solder issues. In fact, you should probably reflow the entire section. Anything in the 400's....
