Hi all,
My K4600 series monitor (K4606) is popping the 1.5a slow blow fuse on the bottom of a Galaxian cab. The inline fuse on my chassis is fine. If I disconnect the power to the monitor the fuse in the cab is stable and it plays blind.
[Disclaimer: I received the game like this, apparently some water leaked onto the top of the cab and the owner turned it on and he saw a "flash". It's been sitting for a year unfixed so it's completely dry. I picked it up "as is".]
Again, the game plays blind if I disconnect the monitor's power cable and replace the 1.5a fuse on the bottom of the cab. So it's definitely a short somewhere with the monitor.
I have a hunch it may be a short in the degauss coil. Anyone have any pointers on how to test? I will probably disconnect it from the chassis to see if it works minus the degauss function.
(I may be wrong here though) (See pic below that I stole from Tighe's thread here: https://forums.arcade-museum.com/showthread.php?t=319272 )
What I've done so far: Cleaned the chassis. I did a full re-cap kit, re-flowed everything while I was at it. Changed B+ filter cap. Changed ceramic axial cap at C621. Changed Black level pot.
Left the 2SC1893 HOT "as is" along with the 2SC1106 voltage regulator (didn't have those on hand, they are on the way in the mail).
Thoughts?
Jason
