Sharp ER-4230F

[Rob Sandberg]

This unit came to us from friend of the owner (myboss)of our company.
He told the customer we would try to fix it.

It is dead no voltages can be found.

Does anyone offer any suggestions or manuals that may help fix this.

Re: Sharp ER-4230F

I am unfamiliar with this model, but here's the list of possible cause/solutions I have:
Move jumper to non-datasym position
Bad AC power cord
Blown Fuse
Broken traces on power connector
Defective main PWB
Program loop (perform program reset)
Program lost (perform master reset)

Program reset: Turn key to 7 o'clock postion and plug it in.
Master reset: With the key at 7 o'clock hold down the "9" key and plug register in.
