Hey guys,

I'm getting a Keyboard Error on my 4000G+ console. Never seen this before. Just reseated all the connectors, and chips both in the computer and in board. Going back in to try to find the problem.

any suggestions?

Stuck key??

I took the whole thing apart. I found brown sticky residue on the keyboards PCB, and some corrosion on some of the components. It looks like a client spilled some tea, or sugary drink on the keyboard.

Hopefully I'll be able to clean it, and get it back up… if it hasn't fried anything already.

Check the 12V rail in the computer. The +12V.

Next time you get the message on the screen, check the LEDs on the computer PSU also as that might give something away.

I got this message a few times and then a few issues with the 12V rail on the computer. I swapped a regulator card over from a 48V regulator card in the 661 PSU.

Worth a try.

Stef.

I ended up disassembling, and thoroughly cleaning the keyboard. Left it in my handy dandy dehumidifier over night, and when I came in the next day, it worked like new.

You'd be surprised how much gunk and other misc objects were in that keyboard.
