Hi. Trying to restore a WWF Royal Rumble that had a few issues. Somehow it appears 80% of the bulbs, including nearly every GI lights were burned out when I bought it. Not sure if it was a lightning strike or what happened to make it do that, but the machine has come a long way in the past several weeks of trying to clean it up. Several parts have been replaced, and all the small bulbs have been replaced with LEDs and are working. I've gotten NVRam and an updated ROM, but have not installed them yet.
The game plays, but no kickers/bumpers/slings seem to be working, nor are the upper play field drop targets popping up (DEAD targets are working correctly). The F5 fuse on the A board labeled "4a Slo Blo Solenoid 32vDC Bumpers, slingshots, etc." was blown. Yesterday, I replaced the fuse for the first time since I've owned it, and it pops and gives that 'burning electronics' smell for a moment immediately when powered on. So i turned it off within about 5 seconds. Then I noticed a small 'puff' of smoke rising, coming from somewhere on the power board near the fuse, maybe slightly to the left, but couldn't see exactly where. That was my cue to freeze my efforts before I made things worse. Hoping for some input on what to check and in what order to find the issue.
Also, the backbox illumination was only working on half the backglass. Turns out, there was a brittle connector at the power board. I would like to get a new connector for that part, but no clue where to source one. Again, hoping someone can point me in the right direction.
Any advice on moving forward on these issues would be greatly appreciated! I'm rather new to this repair stuff, but am a quick learner usually! Thanks for reading.
