Re: Casio CZ1 keyboard issue, please help me
2016-07-05 by roberflas@...
Ok, the battery is for replace in this moment, but i do a reset at power on time, to obtain the factory settings.
On the other hand, I do all checks for contacts of the keys and continuity for traces in printed board.
Anyone tell me that this issue may be caused for one or some diodes of the key matrix.
I will do a test of all diodes, there is 122, two for each key.
