Panel doesn't light up

[John5431]

So I had been sick all winter not playing with the lathe. So this weekend I went down and had a project to punch out. No threads or anything just a couple of collars for my tractor. Turned the lathe on and bam the electronic leadscrew didn't light up except for a light behind the power button. Thought just push the power button nope nothing. Thinking the board is fried or am I missing something.

If its an oldrer display, my best guess would be a bad diplay board. they are very weak at best. Many dont work frome new. Clough42 is now making his owne board now because thay were so problamatic. either get one of his new boards or purchase several cheap ones from Amazon or Ebay. it may take more yhan one to get a good one.

Everything if fine now, just a loose connection on the display board.
