tip102 dead. Repair options? [SOLVED]
I have been doing a ton of work on my bride of pinbot. She is looking great. You guys have helped me a bunch so far and I ran into a problem tonight. First I started replacing bulbs with LED's for under plastics and wow does that look great. I also replaced a switch that I had rigged with some thin wire many years ago and played a game everything was fine, switch worked. I wanted to replace the lights inside the rotating head so I took off all 4 of the sides and cleaned them up really good. There are kickers for the eyes and mouth and while I was in there I pulled up on one of the eye kickers to see how it works (power off). Put everything back together and played another game. Got the balls locked into the eyes and when the kicker popped a ball out of the eye the solenoid was stuck on. The head rotated and it was rubbing on the plastic of the head and I turned the machine off.
Now whenever powered on it pops on. The coil got really hot and I could smell it. After a lot of research (pinrepair.com)I have traced it to a TIP102 transistor that does not give me anything when I use my DMM on it. As pointed out in other posts there has been some repair to my general illumination header pins and it should be fixed again, although working. After reading up on replacing a transistor and seeing the warnings on doing it myself I am thinking it might be a bit more than I want to attempt myself. I bet I could do it, but am scared of trashing the board. I read that it is best to practice on another junk PCB before you attempt it, but I am thinking I better just send it in somewhere for a professional to fix it. I saw somewhere on this board a link to a place to repair it, but can't seem to find it now. Any suggestions on where I should send it for repair?
So bummed and wondering why it happened today. It looks so good right now. At least i will have some time to do the flipper repair and change rubber and lights now.
