The drops sometimes not going down are another frustrating thing
Are you saying the drop physically does not go all the way down or are you saying it goes down but does not register? Had the "down not detected problem" with the three bank TNT drops as well as them going off all the time without being dropped. Stern replaced the PCB and it has been better, I also pushed the ground wires on the IDC connector in with my IDC tool as when I touched it the optos would go off.
Also have the opto going off without the target being dropped problem with the 5 bank, which is actually a bank of two and a bank of three. I have had to re-flow the opto's on them twice now and over time the problem comes back.
Anyone else been experiencing this? Has anyone come up with a solution? Would running jumpers on the back side keep the paths from failing? Anyone else had problems with the IDC connectors to the opto boards? I looked for a schematic for the three bank and could not find it in the manual, is it available anywhere? I have a spare 3 bank to test possible fixes on if we can come up with a solution. I am happy to do some testing if we have some ideas
