Oh, and I also got his copy of the pinrepair guide. Notes and all...so now I know for sure who did the beautiful soldering work that lead to the dead kickout.
shardian:
Lots more reading, lots more pondering, lots more pacing, etc. I was looking at an MPU schematic today, and noticed that the chunk of components below the batteries was the 'blanking' section. I had noticed light corrosion on some CPU pins the other day, so I decided to inspect closer. Odd that the pinrepair guide didn't list this as a potential problem for the blanking LED staying off...
I pulled out the board, and started peaking around. The acid damage was worse than I thought. I cleaned up the components, then pulled the CPU. more damage in the socket. I took off the socket, cleaned up some more acid, and installed new socket strips. Cleaned up the CPU chip, and put her all back together. Oh, and I scoped the board out again for cold solder and blown pads.
I looked closer at the blown pads, and deemed most of them 'okay'. Any with solder side traces appear to have continuity. Those with parts side traces seem okay too. I didn't do too much thinking on this, because I wanted to install the board.
Fired her up, and it works again. The flippers also now properly lock out during fight video mode after reflowing the relay connections. Unfortunately, the left saucer kickout is still non-functioning.
Eh, at least the game works again!
shardian:
Dammit!
I was trying to figure out a way to block off the left saucer, and when I went to turn the game back on, it was dead again. I went to pull the CPU again, and I slipped and it fell down into the cabinet. I fetched it out, and 2 of the acid damaged legs had broken off. Oh well, needed a new one anyways. As I slid the playfield back, it frikking fell off the tracks. Hopefully I didn't break anything.
Can things go any worse???
PS. Anyone have a spare 6802 processor they can send my way?
shardian:
Man...I am about done screwing with this. I started poking/prodding any and all connections on all boards. I made sure everything was good and secure, etc. reseated chips again for good measure, which I hate doing (more later). I took the CPU chip from the spare board I had, so it is complete again. After tinkering with all the connectors, the PIA LED came on and stayed on. That is a first. I can turn it off, tinker with all the connectors again, then the next time the PIA goes off and blanking never comes on. Then I can poke/prod AGAIN, and the game tries to boot to the "Open Coin Door" message. Opening coin door does nothing again, then after a while it (the blanking LED and the game) dies.
Obviously there is more to this. I think the PSU might have some issue.
Last thing. I was getting frustrated, and decided to reseat the game EPROM again, Started to pull it out, then one side gave alot quicker than the other...I broke a mother effing leg off!!!!!
I HATE this crap!!!
njay:
