Lord of the Rings locking up after Pinsound+ board installed

Question

Hey guys

I installed a Pinsound+ board into my Lord of the Rings (Stern Whitestar).  It worked a few times, but now the game will boot and look like it freezes.  The MPU activity light on the Pinsound+ MPU daughter card is solid red.  Any advice on how to troubleshoot or fix this?

Thanks!

Answer 1

The whitestar daughter board led should always be blinking.

I suspect the daughter board is either damaged or not properly inserted, check also the CPU chip on the top of it.

WARNING: take double care of the pin, they will break if bent.
