Just a quick question to anyone that can help. I have a Bally Vector that's in fantastic shape but for one thing, the displays all have a very tiny flutter (not even enough to call it a "flicker") to them. Happens constantly at a steady pulse, and isn't even all that noticeable but I'd still like to find out the cause.The solenoid driver board has had the update mods done to it by the previous owner, and a new C23. Everything looks great, like good voltages on the displays (175v) solenoid driver board, MPU, but not the Lamp Driver board, the 5v is only 4.8 on it.
Is 4.8 too low? Could it be the cause of the display flicker/flutter/anomaly somehow?
I've re-flowed the solder on all the displays, checked voltages on them, pushed the wires in on all the connectors everywhere, pins look good, and this has all helped but I can't get rid of it entirely.
I tried running it without the auxiliary lamp drivers to see if they were what's causing it but no change.
I tried swapping in another working solenoid driver board, and a lamp driver board but no change. Both lamp driver boards were running at 4.8v. Where would the loss in votage be coming from, and again could it be the cause of this? Or? I've scoured the internet for every post I could find on the topic and so far I can't find the answer. Like I said it's not a big problem, I just hate it when things aren't right.
Thanks for any input, just some gratuitous pics below with no real connection to the post lol.
