Need Main Board for a Tombraider

[Akastaff]

After lots of fiddling and checking parts with another machine I have found that my Tombraider is not accepting tokens due to something wrong with the mainboard in the machine...Bitsy part number BM202A (the board with the LED's on that indicate buttons being pressed etc.

Anyone got one or any good at repairing.

I had a main board problem on a fever queen, i removed the board and put in one from a hanafuda.

it worked but payouts were wacky, so I put the orginal board back in and it worked.

so, a lot of times its not the board, 99% of the time its the connections.

I took the board out of the TR that wouldn't take tokens and put it in my 100% working TR and got same problem...all works and sits there flashing INSERT MEDAL but coin just falls through and the magnet is off...put working board back in and all working again so it is def a problem with the board.

Only spare I have is the PSU. and that's a faulty one as doesn't send the signals to the payout hopper

Guess I will get down and dirty with it and scope out where the signals for the token side of things goes, hopefully it is just a standard IC blown i.e. an LS74xxx, as I've got nothing to lose will just go through it until find fault...Surprised how simple the boards are actually..harder without a schematic but what the hell. I doubt is main processor as it is 99% working.
