Your target areas are..
Hey thanks for the reply great... i have a lethal enforcers cab that works that's the only jamma i have to back up. here are some pictures of the chassis..
Unplug the chassis and remove it, remember where your
chassis grounds go each wire should be back where it was.
Next, option one is solder the vertical ic for the lines in picture.
Option two forget about option one, replace the vertical ic
for best results it looks discolored may have been over heated.
which is in the picture top right hand side of chassis mounted to the
Black heat sink with heatsink compound, keep what you can
and reuse the compound grease it is not dryed up yet and can be reused
wipe what you can from the old ic, on to the new Ic.
you need to replace the pump up cap c59 too...
they work together and need to replace them
as a pair, when the chip gets replaced..
all the caps in the vertical circuit may not be needed.
If you would like to do a cap kit then go for it..it will help to restore the chassis
and there are some caps in the PS that are needed at this age for this chassis.
I dont know of a cap kit for the chassis I stock all the caps,never looked for a kit.
Another look at location is the flyback inspect it for any holes they too
are a issue with this chassis just a inspection, also look at the
the resistors behind the vertical Ic for any discolored resistor
just another visual inspection, as PM or Preventive Maitenance.
Another tip is in a case like this remove the signal cable you still
should see these video issues, without the game hooked to it.
Good Luck!
