I have Cisco CHS 335HDC STBs. When I record to my VCR I have audio when the HDTV is on, but when the TV is off I only can get video. This has happened before and somehow I was able to fix it, but I don't remember what I did. I also have a SDTV with the same STB and have had no audio problems with it. I am using an RF cable to connect the STB and the VCR. I have also tried switching out the VCR and the STB with the same results. When I call Verizon they say they do not support VCRs, but think they may have been the ones that helped my the last time. Any help is greatly appreciated.
We're sorry to hear about your troubles using your VCR. Although we cannot trouble shoot the VCR, I am curious about your trouble shooting steps you've already taken. You mentioned that you had switched out the VCR and STB. Does that mean that you used different equipment? Here is what I recommend:
1. Take the VCR to the other STB/TV that you have and see if it will work there.
2. If possible, exchange the STB's that you have connected to the HDTV, just to see if there is some out of the ordinary condition related to the TV. Normally the TV will not be a factor with the type of connectivity you've explained, but best to isolate all that you can.
3. Swap out the coax that you have connected between the HD STB and VCR.
Also, it would be helpful to know your entertainment architecture. Do you have a surround sound system connected? Are you connecting the HDTV via HDMI to the HD STB? All of these are a factor in drilling down to the cause of this issue.
