Ah…
I canceled the order but for 12/15 bucks a new smart controller is on its way.

At least I can print.

Maybe contrast pot came out of adjustment, if it has one?

It has one… And yes… I’ve played with it…
Someone asked me to post a picture of my cabling…
missing/deleted image from Google+

did u check the contrast?

25

ok
definately LCD module was bad…

but also the board… i’ve tested a known good LCD module on this MKS gen… no luck

26

Swap the cables too? With new ones?

27

Yup

28

New screen came with the connectors upside down.

I had that happen too. On bad static zap… helps to have spares.

Yup… Will ship back the mks gen to Amazon…

Problem is… I still need one.
