High Corrected and Uncorrectables!

A field tech was out two days ago and everything is fine regarding the tap, dmarc (sp?), cables, modem, SNRs, dB levels, ingress, everything. However, I keep gettting high corrected and correctables. Please help!

 

Edit: Replies have been added with the information. If any extra information is needed, I'll try to get it up when I get home.Signal LevelsSignal Levels

This shows the uptime so you can see how little time it takes to get the errors that you see in the first picture.

Re: High Corrected and Uncorrectables!

That's not fine, get twc back out

something is corroded or loose

Re: High Corrected and Uncorrectables!

The tech and I covered every point from the tap to the modem. Could the loose or corroded connection be at the amplifier?

Re: High Corrected and Uncorrectables!

The onlything in the log is when cable was disconnected sunday.

See  If there's no new log entries since.

 Then Reset the modem and see if the correctables and uncorrectables are still going up...

There might be about 500 per channel right at startup
