Quoted from interconnect:Having an issue and wanted to see what you you guys think about it. A few times I've seen the 3X light up when it's not supposed to. Was lit up about halfway. Now today, I just saw the spinner 2000 do the same thing, at the same time as the 3X light. Kind of lit up halfway and flickering a bit. My wife mentioned that she's also seen the Shoot Again light (in the playfield) do the same thing, along with the others. Now, I don't think it is a ghosting issue, as I have a non-ghosting LED in the spinner 2000 light (my 3X light is just a regular LED; going to replace the rest of the LEDs with non-ghosting ones here real soon). I don't think that'd explain it.
I was looking at the Lamp-Matrix table and see that the 3X and Spinner 2000 lights are in the same row, although the Shoot Again one is not, however it is in the same column as the Spinner 2000 light. Could these all be related since two are in teh same row and two in the same column, with one being in both? Also, my MPU was just rebuilt/repaired at K's Arcade. Do you guys think it could be an issue with the 1J6-2 & 1J7-6 transistors (is that what they are?) Maybe just dirty/corroded contacts in the bulb sockets? Just wanted to see what you thought and how I could test it to figure it out. Thanks in advance.
Sounds like what mine was doing.
Check my MPU repair log a could posts back. (Probably on the previous page)
