Hello !

I got a used Solton MS50 keyboard that looks like it had a very hard work till I got it,
anyway, when I power it up it gives me a
"Error: No keyboard avaliable". Than it boot up and the keyboard doesn't respond. Sometimes it doesn't show anything on the LCD display and sometime boots just fine.

I opened it up and checked that all plug are inserted correctly, moved the chips on the PCB to assure there's no bad contact but it didn't help.

I will be thankful for your advice.
