Quoted from Man314:New board came in today. Had it installed in 3 minutes and viola, my Pin is back to its original glory. I kinda like that this replacement board has a variable brightness.
Still don’t know what that empty fuse is on the power board. At 1/4 amp it can’t be controlling much. Everything is working, so I’m not too worried.
Those fuses were for the high voltage for the old plasma displays. Either there was a short in one of the display glasses or (more likely) the high voltage section itself had a shorted component. Either way, since you replaced with a LED display that does not use high voltage, you can safely remove those fuses and leave them out.
