I've notice some of the inner LED lights flickering (top/right) or trying to complete a rainbow of colors that looks a little off (top/left). This is going on with the top four rows encircling the T2 Green Ship. Sometimes there is no light at all though I don't know if that's part of the show. Is this usual or a sign that the lights are going bad? Are they a easy fix? Would I unscrew the front panel (removing art) from the cell to get to them or go through the back wires and guts?

I know this is an older machine so I know there might be some up keep though is this usual?

Should I even bother and take it back to Hiro?

Any thought?
