I was reading an older post here that had been placed here about a fault 86 and already did what was indicated to replace the 10v 100uf capacitor C3, but the error continues.
Does anybody know other possible causes for this fault?

Regards

Fault 86 may be due to a faulty motor. Try replacing the motor.

the error was mine i was changing the wrong capacitor . Problem solved .

Thanks Anyway

It takes a Man to own up to mistakes in Open Forum, Serroni.

So ... it was the usual suspect after all then (C3)?

yes it was the c3 but i was changing the c3 from the power board.

Then i see tha it was from the PCB Main that needs to be changed.

Hi guys,

I have one Grasbey 3100, with Fault 91 on screen, anyone can help with the service manual or suggestions most welcome

Code 91 is a "keyboard fault".

The manual suggests "replace keyboard"!

But first check for a stuck key "button", fluid "ingress", bad connection(s) ... and all that usual stuff.

usually, when it comes to "keyboard fault",its only need general cleaning

Geoff and Ariel,

Thanks for msg, will check and let inform you

Yes it does solve, i wonder why couldnt they display " check keypad" instead of Fault 91.... anyways thanks guys need anything just send email....
