I was having trouble with a pop bumper on my touchdown sticking on. While troubleshooting
I was making the switch from underneath with a screwdriver (a very big mistake) and shorted the coil voltage to the switch.It died as soon as the short occurred.All I get from it now is the GI works and the score displays show all zeros. The credit display is blank and it does not respond to any buttons. I have had successful troubleshooting and circut board repairs in past.I just do not know where to start with this one. I tried to trace back it on the print and if it sent high voltage on the +5v circut It could be multiple problems.
Anyone have any advice on where to start? I ordered a logic probe as a start.
Thanks Jim
