I am not sure how it happened but it did. My sat system consist of two dishes. One for Ku and the other for C band. I have been working with this setup for a while now. A few weeks ago the Micro started to not recognized the DiSEqC. I tried switching ports and nothing. I get no signal from lnbfs. I thought that the switch was bad. So instead of replacing the switch I replaced the receiver. The Manhattan had no issues with the DiSEqC. Has anyone encounter the same situation?
