Quoted from VividPsychosis:
I have the newest machine from the newest production shipment, if you consider my machines issues trivial, then I guess you have low standards. New shipment 1 out of 1, no where near 100%
I 100% agree than no NIB game shoudl have any issues.
That said...just curious, is this really your only game? If so, then I could definitely see this as being a much bigger deal to you and being extra frustrating.
Reality is that all of your issues sound like things that will eventually be fixed but are more troublesome due to lack of experience. Your loud sounds and electrical interference stuff when hitting flippers sounds like you have a plug that is partially disconnected/ getting interference through HV line. I would slow down and start tracking the HV line from coils to see if anything is loose form transport.
The EL side panel issue sounds like either a defective EL unit or some interference again from wires wrapped together. For now I would just unplug the EL power supply and remove it form the equation completely while you troubleshoot other stuff.
your flashing different RGB lights thing is from vibration and not HV line likely. I would guess you have the same symptom if you lightly pound on the playfield. The GI and insert lights are all serial in nature and the RGB requires that multiple lines (R, G, and B serial lines? which come through the larger under pf boards) all have good connection. I would check around and find the loose bulb and reseat all the bulbs. Again the transport is hell on this and honestly this is a poorly designed system (although sounds like production games are more like FT was which was rock solid).
Your xeno head appears to be a physical adjstment. Either cables in the way ot just the actuator switch wire needing the smallest adjustment.
IF this is your first game, then time to get a local with some knowledge over to lend a hand. Yeah, that should not be done but reality is all your symptoms really do seem minor to the trained eye. I wish I was local to you as I would come over right now and try to lend a hand. I remember how frustrating it was when I got my very first machine, had not idea where to start, and had tons of issues. a Few years later and all those huge issues were actually very minor just larger from my lack of experience.
