Lets fix a non booting Bally pinball MPU

[@christianalmberg5915]

Lots of good advices here in this video. Just one thing. Your’re blasting those through holes with that large solder tip. Try using a smaller one. Its well worth it.

At 1:50 you have your probe at "spot 38". What's that? It looks like it's touching pins 39 and 40 of U10. Please advise.

RUSHFANPINBALL, when flipper coils either don't have any diodes or the diodes went bad across the coils it will send back voltage to the MPU board which causes the game to RESET, any reasons why it causes the MPU board to Reset?

Really good info, BUT, do you think you can jerk the camera around and get it out of focus a little bit more.

[@rushfanpinball1604]

Probably could!

My Dolly Parton mpu has a red lamp instead of green, is that normal. Either way it's not coming on at all.

Stern pinball boards are interchangeable with Bally's of that era and have a Red LED. If it doesnt boot this video was a quick guide. Lots of info on the web you can refer too. Hope you figure it our!

Hello I have the led blinking 4 times

[@rushfanpinball1604]

Google Bali MPU flashes four times and a lot of articles will come up. 4 flashes is almost there!

I'm working on a strikes and spares right now and it too had 4 flashes. I put left pressure to the lower left connector j4 on the mpu and it booted up. I removed each pin on it and sanded the black off each pin ok now.
