You can break off legs from a donor chip then solder them onto the old stumps to fix the chips back up. If the legs broke off flush with the plastic then you gently dremel away enough of the plastic to make a solder point for a donor leg.

Confirm your voltages at the PS and at the chips.

I'm in the midst of trying to fix a F&F 2004 Raw Thrills game. The computer has died. The original motherboard is a MS-7061 VER:1.0 KM400 8237. I replaced the motherboard with one that I had, not a match to the original, but has the parallel port for the dongle. I reloaded the machine and it all...

Raw Thrill games use a PC that has a parallel port. It needs the parallel port to plug in the security DONGLE. Make sure you get the dongle or you still wont boot up.

Can you explain why a 10 ohm 1/2 watt resistor CAN NOT be used in place of a 10 ohm 1/4 watt resistor.

Do you have the link to the Open source schematics? I cant seem to find them.

Does anyone have schematics for the ADD-on Boards that replace the KONAMI Custom Chips? I know I can buy them from someone here that has revered engineered some of them. I'd like to build my own boards for my own games.

Did you ever get any further on this project? I would like to see if the chip images can be layed out to print as the actual chip size so they can be cut out and stuck right on the chips on the board. This would help some with following the logic easier without shifting eyes from board to...

Anyone have a DOLLY PARTON Backglass for sale?

Looooooong shot. And I am thinking that there is no longer any in existence. In most of the WILLIAMs repair manuals, at the back is talk about a troubleshooting vhs tape available. Just wondering if anyone has one of these floating around?

Actually this is a hobby that can be fairly inexpensive, IF you spend alot of time. It depends how deep you want to go with it. Your $140 board repair could have been a 30 cent chip replacement...."If you knew how to do it". But this takes Learning time to understnad electronics and...

Hey Jake.. I have worked on a few of these boards. I HATE them. As far as the Missing red color goes, you will more than likely find that one of the 6 PROMS on the video board are bad. I put together all my Repair Notes on my website. Check it out...

yes... won't stick worth a damn onto textured base. Why use textured if you are putting a CPO on it?

Not a big fan of using Laminate. Did these cabs come original with laminate? Or laminated during its life? I would try to strip it and paint it back to AT LEAST its original base color. THat way you can apply sideart at a later date. I think a good paint job sanding and smoothing can give great...

Have you made sure you have tied ALL the ground points on your board to a good ground? Also make sure your board grounds to the monitor as well. I had the similar incident and found a lack of good ground. As far as power supply, I rebuild the originals and they work great when rebuilt. And the...
