I have a half dozen or so PS2 boards that I'd like to salvage. Some operate fwd/bk, lights, but no sound. Some with sound, lights, but no go! I've mixed and matched PS1 boards with success, and was hoping to apply the same theory to the PS2, but they appear to be soldered together? Any thoughts? Where MTH doesn't produce the PS2's any longer, I wonder if they'll make the schematics public, sometime in the near future?

Thanks,

Joe

This tool would be one way. You have to thoroughly heat all of the pins at the same time. There are variations of this tip but I could only find this pic.

Another way is with a heat gun with a narrow funnel about 1/2" at the outlet.

lastly you could try and cut all the connecting pins and unsolder them one by one. 

If this is a multi layer board, chances of success are pretty low. If not chances are better.

You realize the chances to damage other components near by is high?  Plus if the processor or memory is bad you out of luck.  There is a reason they are obsolete and where replaced after a short 4 year run.  Lights, motion, sound can all be fixed without separating the board.   Your about 10 years late to the game of salvaging 5V boards.   Good luck.  G

First off, thanks Pete for the link!!! Second off, thanks GGG for your experienced reply. Though you could have pointed me on the right direction to troubleshoot the no go and sound issues (LOL). It's not my intention to hang out a shingle with "I fix Proto 2 boards", that's NEVER going to happen! Nonetheless, I respect ones knowledge to be private. I'll poke around with the Proto's. My knowledge of electronic circuitry is based on Electro-Mechanical , and Digital pinball repair. Different than "O" gauge boards, but theories apply.

Thanks all,

Joe

Most of what you seek is posted on this forum one place or another.  Not really keeping it secret.  MTH keeps certain print to tech only.  Not suppose to be posted, but example do show up, and Stan had pointed out with pictures much of the stuff.  How to remove and replace audio amp is listed here too.  Lights are fet, motor control is the larger fets at the Relay.   G

This Association of collectors is fantastic! I wish I could contribute as much as I've received! I need to learn my way around the forum/site better!!! I see you've referred to "how to stuff" being mentioned in past posts. Is there a "search tool" to track down these posts? i'm torn between my 5V and 3V PS2's to repair, as obviously the 3's split without de-soldering. Regardless, I had built myself a test fixture for PS1's and PS2's, but the fixture is only as good as a better understanding of chasing the circuits. Learning that the relay for the 5V bds is a great start, now the 3V must have a comparable component that I can test and change.

Thanks to all of you!!!
