Hello anyone,
I have been running into a TV issue and I am hoping someone can help me. Up until last weekend, I was able to use my Cisco Explorer set top box (I'm not sure offhand which model it is, but I believe it's a 4652HD) using component outputs to my TV without any issues.
However, I moved the set top box to a new location which has been known to work before and I am now unable to receive any signal. The set top box takes forever to initiate the Rovi boot sequence, and when it does load I get nothing but a black screen with grey bars (and the guide shows no data - please see photos for both the grey screen and the no data guide). I called tech support on Sunday and after using a different coax cable, I was able to obtain signal and watch TV normally. Everything stopped working again yesterday after I reset my cable connection signal (due to the fact that I have a few channels including ABC that were not showing up - Temporarily Off Air message). I am now unable to regain programming.
From this forum I have found a way to access the system diagnostics, and under RF Network I see the following metrics:
Tuner: 171 MHz -20 dBmV, FDC: 74 MHz -39 dBmV, RDC: 13 MHz 37 dBmV
Should I call a Cox technician to come by and adjust my signal, or is there something I can fix to help with this?
Thanks in advance!
