    I’m a noob for sure…just getting into pinball. We’ll just start there.

    Recently acquired a great TSPP. I updated the lights to lcd and added the OCD board. No issues. I installed new speakers - no issues. I tried to put I a pinsound+ board (which seems to power on), but now the display, speakers and half the lights no longer seem to work.

    I checked the fuses with a multimeter (had to read how to do that and may have done it it wrong), but they all seem to work. Could it be something with the processor I pulled out (and then reinstalled) to install the new soundboard?

    I have since uninstalled the pinsound in an attempt to get back to working but to not avail. Thoughts? Thank you in advance.

    Can you start a game? I assume not.

    When you reinstalled the processor, you made sure the processor is not 180 degrees rotated? It has a notch at one end and this should be on the same side as the other ICs on the board? I think it’s downwards.

    Thank you. I tried both ways with the same result (per the manual the tab does point down - thank you). I’ve ordered a new mpu to test (and since I’ve now bent the little holders) and then will call the professionals. I’m learning little by little.

    Please don’t try it both ways, this likely has destroyed the IC.

    The question is, the first time you tried it was it correct or reversed?
