VMS4100 and Sony STR770

The Arris Set top box has a problem working through the AV receiver. Verizon tech support don’t know how to assist in this case.

The STB identifies 720p as the resolution and then if switched off cannot output any image through the receiver. When connected directly to the TV it still does not show a signal. It’s at this point not getting the handshake or the resolution has gone wrong.

If if I keep the STB on then the system works powering the receiver and Tv off and back on but it then goes to 480p.

is there a way to access a service menu? Is there a way to fix the receiver to stop the repeated resolution changes and speed up the handshake.

Clem, many thanks for your reply. As a point for folks who have handshake issues use a hdcp converter.

In in my case the resolution was to use a blackbird converter to make this a hdcp 1.4 output to the TV. Now have a solid connection to all devices!

Try menu, settings, voice control, Fios TV voice remote, program fios TV voice remote, reset remote setup. Then do the manual setup for your receiver and see if that helps.

Also from the Sony manual, look at this:

Press AMP MENU, then select
“<HDMI>” – “SIGNAL FMT.”. Select
the input you want, then press .
 STANDARD: Selects this when you do not
use high bandwidth video format.
 ENHANCED: Selects this when you use high
bandwidth video formats such as 4K/60p
4:4:4, 4:2:2 and 4K/60p 4:2:0 10 bit.
For details on the high bandwidth video format,
visit the Help Guide.
When “ENHANCED” is selected, we recommend
you to use a Premium High Speed HDMI Cable with
Ethernet, which can support bandwidth up to
18 Gbps.
Some devices (cable box or satellite box, Blu-ray
Disc player, and DVD player) does not work well
with “ENHANCED” setting. In this case, select
“STANDARD”.
If your TV have similar menu for high bandwidth
video format, check the setting on the TV menu
when you select “ENHANCED” on this receiver. For

Thanks for the reply. I have cec on and off. Enhanced and standard. Thru and no thru signal.

The receiver is identified correctly but when the tv is switched off the handshake does not happen. I am not sure why the handshake can occur initially and then fails. If I can keep the STB in a non handshake setting that would work.

STB has to make handshake with receiver or TV no matter what to satisfy DRM standards.
