T340 + ( POG ) Repair

[pcrev]

Hello folks, I am new here and I need some help. I am an electronics technician and work for a company that has more than a few POG machines out in the wild. We run 510 and 580 software mainly buy still have some of the old 400x boards that still work. I am the one who builds the machines from scratch and I also work on the boards as they fail and come back in. I have looked for hell and ever for someone who knows these logic boards, not the software, I know that inside and out, but I need help with the  actual board. We have a lot of failures that range from touch not working to bill acc. rejecting bills and the biggest one is the board not booting up. I have learned alot on my own but it sure would be helpful to have some documentation on the hardware ( I have several different manuals for the software ) so if there is anyone out there that could point me in the right direction, it wold be awesome.  Thank you for your time and have a good evening.
