Here I am again with questions regarding my father's T2 pin. It's been out of commission for a couple months now because I haven't had time to get over to his place to take a look at it until now. The problem he was having was that when he would start a game it would show that it couldn't find all the balls. I tested each of the switches in the ball trough and found the Right Trough (17) switch wasn't registering as open. When looking further I found it was that entire row (row 7 on the Switch Matrix) wasn't working.
What initially caused this issue was that my father put his hand under the game when it was on (he's not sure why...) and got a nice sized shock. So my guess is that he shorted something. In the manual it shows that this row runs through the U19 chip. Is this what I would need to replace? Where do I find this part?
ALSO... I noticed that when testing the microswitch with the playfield lifted up it would register when the switch was open/closed as though there was no issue but as soon as I put the playfield back down it wouldn't register when the switch was closed. I checked to see if there were any wires that were getting pulled on or something when the playfield was closed but couldn't find anything. It just seems strange that it would work fine with the playfield up but stop working when it was down.
What am I missing?
