Well, tonight I'm going to plug up the freshly cleaned and scrubbed PCB/Cards and see if the red-screen-of-death goes away. If it does not then I think I may look at buying a new monitor chassis for the WG K4605. It at least needs a recap either way.
On that note, is there ANYthing that can be done about screen burn? This monitor has some, not much, but it's definitely there.
Mauzy:
Screen burn can only be remedied with a new tube.
Wait until you can replace that resistor (or at least reconnect whats there) to go buying new chassis. That could be one of those cases of a $3 fix bringing a machine back to life (though the red screen does sound like a board issue...)
Kevin Mullins:
K4600's like any other monitor of that age is gonna have bad solder joints. A higher wattage resistor like that is a prime place for that to happen. So the leg may have had the joys of corrosion/solder joint/arcing and finally the leg gave way. (burnt itself right off)
#1 thing is to get the game to play "blind" at least.....then move onto the monitor. (which most certainly will needs some TLC)
Those vertical cards that plug into the main chassis are also notorious for bad solder joints where they plug in.
Red screens is signs of life on the monitor, more of a reason to be concerned with the game boards right now.
SirPeale:
From what it sounds like, you're FAR away from having to buy a whole new chassis. Sounds like the one you have just needs a little work.
Recap (not cap KIT because they often don't have /all/ the caps, and they /all/ (except the really big one) need replacing. Retouch every solder joint on the board, particularly on the daughter card connectors and the flyback.
As said, the only cure for screen burn is a replacement tube. You may find a compatible one on the side of the road, or at a recycle center. Me, I have a TV repair place up the road from me that will let me have whatever I want because then /they/ don't have to pay the disposal fees.
I've been told that this project encompasses all the caps on a K4600, but I haven't tested that myself. This list did come from a trusted source, so take that as you will:

Add your resistor to that list and that's a starting point. Also if there are any electrolytic caps on the Gorf board, you may want to make a list of them and add them to the order. After all this time it would not surprise me that they need replacing too.

Cleanup and tear down slowly progressing. Took out a few more pieces last night to clean. I also spent some time and labeled a lot of little wires so when the wiring harness is ready to go back in I will actually be able to hook it all back up. =) The joystick parts and 25c plates went thru the dishwasher and came out looking very nice. Some of the aluminum parts are going to require a good steel wool or light sanding to get them looking new. The marquee is in fine shape minus a few small spots on the back where the screen printing has come off. These spots are very noticeable, does anyone know if painting over these spots with a matched paint would be ok or would that just show up as dark spots when backlit?
