Ordered a new Ni-wimpf board. Took off the old one and the one chip is fried. Got the new one to make the machine work and play, but the 4 red targets in the back does not reset, the roll over targets do not register or chime and there is still a short out there some where. Love the Mark II board but I have to fix the short before this one shots. I have a tech coming over tomorrow to find and fix the short and replace the drop targets with new ones. If anyone is interested in this board let me know and I will ship it out to you.

Wow, I haven't seen scorch marks around a socket like that before.

If I discover a chip that is too hot to touch, I turn the game off immediately. I guess that is what happens when it's left on too long

If you really want to, you might be able to desolder the socket (with the proper tools, of course) and replace it and the chip and have a working board again. But, if you really don't want it, I'd be willing to take a crack at it.

Feel free to DM an offer my man. You are the most knowledgable guy on this machine, and I can not thank you again for all the information. I am done throwing money at the machine and I am praying the tech tomorrow can fix it for me so I can just play a little on the machine.

A quick update: The tech came and after hours of picking at everything there was a couple diodes that were shot, a few switches that were shorting the boards, a blown transistor on the new rotten dog driver board, and the MPU to Driver board connector (new one from docent electronics) was shotty. He replaced the drop targets, so now we are going to replace the diodes, the transistor is going to be added to the new board, and once docent sends a new connector it should be ready to see what it all says... Hopefully this thing will finally work. I will never get rid of this thing... lol
