My Borg ship flashers aren't working anymore, well not the way they should.
A little back story because I don't know if it's related or not. When I first got the machine everything except the shield GI lights worked. There were a few flashers that were out but at the time I didn't even know they existed. I eventually traced the shield GI problem back to a miswired J121, someone before me had put pin1 in the #2 position. When I repinned it, the shield GI lights started working but the flashers (that had worked before) stopped. I found that the Romulan and Right Lane flashers (along with the others that had always been out) were incandescent bulbs that had blown. Replaced those and they work, but the Borg Ship Flashers are still FUBAR. They are 12v LED flashers. I took the ship plastic off and found that on the right ship circuit, one of the SMD does actually blink faintly. I have checked the sockets and they are getting the proper voltage, and all have continunity to their respective pins on J122. This leads me to believe it is a problem on the power driver board. Now, I pulled the board and checked all the transistors and they appear to be good. I did find C11 with a domed head about ready to pop. Once I got the board out and looked at the backside, I decided to just replace the whole thing (alot of homemade trace repairs, shoddy soldering, heat damage, etc). There is a little blue sticker on the board that says "Repaired 6-22."
So I guess my questions come down to, would a bad C11 be causing just those 3 circuits to not work, and is there anything I need to check in my machine before installing the new board so that I don't smoke it? With the board supposedly repair just over a year ago, it seems to me that C11 should have lasted longer unless something else is inducing a failure, but then again, I don't know what all was done during the "repair."
One final note, here recently (a few weeks after the flashers stopped) the Under Diverter top will randomly kick several times in a row. I can't find anything that seems to trigger it, it appears to be random except during Final Frontier, it will kick during the entire time FF is going. Never sticks, just on, off, on, off etc.
