clean the rotary encoders first. if the scope start then firmware is ok. you can't flash that scope. the firmware sit in UV eprom.

without conection keyboard is the same address error.
I know that, firmware is on UV EPROM. I need 2 hex file to reprogram EPROM.
Do you have the same equipment? Are to able to dump firmware chips?
