hey guys! Just picked up my first pin , checkpoint! It has a new rotten dog power supply board and a new dmd display. I’m learning the ins and outs on this one and while it is in working condition , it has little issues.

Issue 1# the lights under the “turbo” art and “boost” Art beside the flippers don’t work. They’re chained with a bunch of other lights and also don’t work. Multimeter shows zero volts dc. Where should I be looking?

Issue 2# the speaker inside The pin had one wire taken off, so I soldered it back on but it still doesn’t work. Then I found out the left speaker in the back head also had one wire disconnected so I soldered it back on and it works now but it’s quiet. I went to the sound board and found the connector that has all the wires and where it’s labeled sp3 (speaker in the pin) the heat sink , first one from the top can give you third degree burns. It’s producing extreme amounts of heat. Why??

Issue #3. This sucker hums pretty good and loud on the attract mode. Tried tightening the screws in all boards but it was a no go.

After taking the picture of the pin, I noticed my coin return lights are no longer working either lol

Thanks guys!
Also Changing my speakers To some pyles I found today for cheap

Can anyone show me these two things?

1. How is your spin and win column mounted?
2. Is there supposed to be an orange plastic bumper piece here where the white rubber is, like the opposite side ? The ball gets stuck here sometimes

So I changed my speakers and still only the right side is loud/works properly. Left speaker in adjustments menu is super low And the in cab speaker is pretty much not working at all. On the sound board, the top heatsink/amp is Scorching hot, it will burn your finger. Caps look new but I’ll change them anyways. I saw here that you should recap the power supply also so I’ll do that too. should that amp be replaced on the sound board?

Am I missing that big transistor and a resistor at Q1 and R19?

I replaced the left flipper coil because the sleeve was seized inside the coil (found out during a rebuild). Now when I press the right flipper button, both the flippers move together and very weak , but if I press the left flipper button the left side moves only. What did I do wrong?

Also my vuk Eject stopped working , is the coil supposed to be energized always until the ball sinks and hits the switch? (Someone taped up a diff switch to the rail, switch registers when I press it)

Anyone have any idea why my flippers are both working when I press the left flipper button? Or why the vuk eject doesn’t work? I can’t figure it out
