Arcade Repair Tips - Replacing Lights In An Arcade Cabinet 

Hi, Adam! Basically, the system for the fluorescent lights is very simple - bulb, bulb fittings (T5 or whatever), a starter (with its fitting), ballast and wires. I think that it will be best to check each other in the order I'm typing here. The fittings have 2 small metal strips in them - you can remove the cap with the 2 oval holes to see them. If they are not new - check for oxidation or for a bad contact with the bulb. I'm almost sure, if everything is new and working, that you have a wire or wire connection problem. If nothing is working - check if you have a voltage to the light's connector (well...you should check that first). :) Don't forget about the safety, always touch with mains plugged OUT and check with a multimeter with mains plugged IN (but DO NOT touch the wires or near them). And for the game counter - it's simple because you have only 2 options - wires check and changing the unit. The way it's working is - you have voltage leads and a signal input. When you put a coin, the signal input is triggered (oftenly - HIGH) and it turns the mechanics in the counter by 1 unit. If the wires are good - it means that it's electronics (or oftenly - mechanical) problem with the counter that's not worth trying for fixing it...they are pretty cheap. A nice lifehack for checking it is to figure out which wire is the signal and try to make a "dummy coin" aplying some voltage through it. Try to find some videos on how the counter actually works here on YT - I'm sure they are many. Best regards, Bobby

Use a multimeter to check power to the marquee light connections and see if you have power. If you don't you may have faulty connections or have a power supply problem... If the counter doesn't tick, it is most likely bad... Test power to that when you insert a coin...
