I did that and cleared the backup ram too same result, I feel like maybe one of the 74LS245Ps is out.

Yep

Some pictures.

Got a 4 slot from a friend that was not working, I patched a trace under the battery and got it to boot. Only issue is I get sound out of only slot 1 and 3 but not slot 2 and 4. I already cleaned the slots and inspected the board for for broken traces and found none aside the one under the battery.

Thank you.

anyone got the manual for version 3.2? curious what sw1 does on that. is it a jamma/mvs selector?

Before you got swapping onboard ram chips look a the ppu pins. Make sure none are bent shorting or loose.

you changed both caps? 22uf and the 2.2uf?

I see one here. https://rb.gy/435d7i My other question would be is if the guy ever swapped the transistors I swapped on that sync module board? Mind you I swapped mines but have yet to test it.

did the sync issue go away? can the hv issue be an issue with the flyback? did the flyback ever get replaced?

Ever got the chassis back from the staten island guy?

Possitive feedback for @bgwelistyl , great communication and the item arrived quickly and well packaged. Highly recommend.

Interested

I am just happy to learn and help, I had to figure all this out on my own. So if it helps make it easier for the next person I happily share the knowledge.

Yea just gget it from a donor, it's easy you heat the solder and at the same time pull the pin with a needle nose and it will come right out no problem.
