Bought my first Pinbot and had had an issue come up a few weeks in.

Turned it on one day and fried the Q79, Q73, and U50 on the CPU

blew the F1 fuse on the PS

Fried the coil for the upper pop bumper

I’ve replaced all of the above except the U50, I’m wairing for parts and plan on soldering a socket in place to make future burn outs

Has anyone else had a coil short like this that blows so many transistors? I just want to make sure I’m not missing something else.

Thank you

Was it over fused ?

Quoted from Wariodolby:

Was it over fused ?

I’m not sure, I didn’t think to check before I threw it away. I have the correct one in there now.

All fixed! Looks like it was the coil short that fried everything else. Thank you!
