First off, I know how you feel. Many years ago, I bought my first pin, and it was plagued with problems. I was really upset and wondered what I had gotten myself in to, not knowing at all where to start. However, like you, I was determined to learn, and that is really the most important thing. Working through these issues will teach you a lot about how pins work and give you the confidence to buy more. So, do hang in there.
Quoted from Kkoss24:
The N and B stay red,oz not lighting up,crystal ball not working,tornado not spinning,bad switch return mid left,the bricks leading up to 1 on spiral stay same color ,a few others ...my kid played it when we picked it up I made mistake of not looking for things like I said it’s on me but this is depressing...I want to get into learning how to work in them but don’t know how to start ..
Let’s think about these one at a time.
The N and B staying red could be either a bad connection with the data cables to that light board or a bad board. You likely don’t have the 2.0 lighting system, so your light boards are going to fail more often. When you get more confident working on pins, you can always convert to 2.0. In the meantime, that is an easy fix with a new board if one is required. However, let’s save this issue for later, including how to tell what board system you have, because it is more complicated than the others.
Crystal ball. Does it not work at all? Is the image garbled? Be a bit more specific. The more info you can provide, the better we can help.
Tornado not spinning. Easy fix. Just add a variable two direction motor with opposite end adjustments and real time feedback. Nah. Just kidding. As others said, it doesn’t spin. Just sits there looking good.
Switches. In switch test mode in the menu system, press the switches that are red. Do they work there? If not, you will have to learn to lift the playfield and examine the switches for broken wires or loose connections. The munchkin playfield might also have a separate connector leading to the main playfield that is associated with those switches. Look for molex connectors being unplugged in that area.
Bricks leading up to 1 are painted on the playfield and not clear inserts so they stay a similar color. That is likely normal.
You need to add a cliffy to the munchkin playfield at some point to prevent damage. But don’t worry about that now. Just tuck it away in your mind for later.
I would start with the switches as that is likely the easiest thing to work through now. Please report back. Take your time, and know that lots of people in this forum will help with some clear description of what is happening.
