Hi,

First what type of encoder used there whether it is a anlog or digital . If it is an anlog type check the input voltage of that. (take the data sheet from internet). If the input is not present check the previous stage.

Suppose if it is a digital type check the out put using CRO and it is not correct check the input of the encoder.

Suppose for both the cases input is ok, then change the encoder IC.
