Quoted from Stal8080:
I was re reading over your initial thread in regards to your X Files issues. I'm abit confused when you started installing leds....it seems initially that that may have triggered the phantom cabinet hits because when you removed a few it corrected itself??? However later after consulting with a few fellow pinside you thought it was misaligned optos ie post 23 in original thread?
I know my machine was modded with LEDs so I'm wondering if that was issue??? Just really want this fixed slightly frustrated because this game is like center piece of game room.....I know part of the hobby
XF was a very tricky beast. It was the one, and only one, Sega I ever owned, and I'll be honest - XF made me swear off Segas. It was the Ferrari of my pinball collection by a mile.
When I installed those LEDs, I was brand spanking new to this hobby. I am coming up on my 3 year mark (read: still a n00b, just have a small amount of knowledge now), so if I did something and ALL OF A SUDDEN something was malfunctioning, I quickly inferred it was due to my action (in this case, installing LEDs).
I have heard and read that installing LEDs near optos can make optos register false positives - in this case - the phantom file cabinet hits. My advice, pull ALL LEDs near the optos or just pull them ALL out and see if the bad behavior stops. If not, it could be possible that the optos are not 100% aligned to each other. Put your game in switch test, and take your open hand and swat the playfield good and hard in random places - see if doing that causes the opto switch to trigger on the switch test screen. If it does, that means the vibrations are causing the optos to be slightly out of alignment for a very small period of time - meaning the optos are NOT in alignment or are off enough to cause random file cabinet reactions.
I swear, this game made me fear optos so much. When I found out they were in BSD, I almost lost my lunch. I was terrified of them after XF. After working with them more and more, I am learning they are not so bad; XF just didn't utilize them very well or the design was bad or something....
