I've had DirectTV for 2 years with the HDMI output from the DTV box going into the AVR and then AVR to HDMI 2 (ARC input) on the TV.
Normally we watch with TV audio, AVR off. When we want to use the AVR sound we turn it on and it switches.....no issues.
A few weeks ago we switched to Xfinity and their 4K reciever; same setup.
We've having an issue when the Xfinity receiver gets powered up (it's set for energy saver mode just like the DTV was), it comes up with audio (most of the time) but no video (most of the time). I've swapped out HDMI cables and Xfinity has swapped out their receivers, but still having the issue.
Is this something you've seen where going through the AVR is causing this issue? Does it sound plausible? I like the setup the way it is, but obviously having to yank out the power cable most every morning is not something I want to continue with. For what it's worth, Xfinity has no clue (but that's another story).
This has been a very common occurrence ever since HDMI was first introduced 10 years ago, known as an "HDMI handshake". It can occur with any brand of AVR and any source, more often with cable/sat boxes as they are more commonly used. You can often mitigate HDMI handshakes by powering on each component in the HDMI chain as follows: TV, pause 5 seconds, AVR, pause 5 seconds, source.
Additional helpful information:
HDMI handshake issues will most often present as "audio dropouts" or sometimes video display issues. Ensure the source device having the issue has the latest firmware installed and has been reset (ie. powered down, unplugged for a few minutes, then powered back ON again). For a more detailed HDMI reset try the following procedure ....
- HDMI HDCP reset
- With all devices powered on, remove the two HDMI cables at both ends from the source device to the AVR and from the AVR to the TV.
- Power off all devices and disconnect power cables to all devices.
- Wait 10-15 minutes.
- Reconnect HDMI and power cables to all devices.
- Power on the devices in this order ... TV, wait a few secs, AVR, wait a few secs, and then source device (although this is the generally recommended order, in some instances, you may have better luck powering on the AVR first and then the TV, then the source last ... bottom line if it's still not working, try a different power on sequence).
If the issue only involves the cable/sat box, HDMI handshake issues with cable/sat boxes are quite common (with any brand of AVR) and are usually always the fault of the cable/sat box not being designed to be connected to an HDMI repeater (ie. AVR) which is why they work without issue connected directly to the TV. Give your cable/sat box provider a call to see if there is a separate firmware update that can be applied to the box to resolve the issue although note that in some cases, a future firmware update to the cable/sat box may very well cause an HDMI handshake issue as well, so your best option to avoid the issue now (or in the future) is to connect the cable/sat box HDMI directly to the TV and also connect an optical cable from the cable/sat box to the AVR for surround audio. If you don't have an optical cable available, and your cable/sat box has a coax digital "orange" output, you can also use a coax digital cable (note: a "yellow" composite video RCA cable is a suitable substitute) and connect it to the SAT/CBL coax digital input on the AVR (ie. right next to the optical jack). Note that with this configuration (ie. HDMI straight to TV) you will lose the GUI/status menu for the cable/sat box, but you retain the capability to watch TV using the TV speakers only with the AVR in Standby (eg. news, sports, wife, kids). Another option, if your AVR features a component video input is to connect both a component video cable and an optical (or digital coax) cable from the cable/sat box to the AVR noting that although you gain the GUI/status menu feature, you will lose the capability to watch TV using the TV speakers only. You may also want to try upgrading to a different model cable/sat box.
Other possible solutions:
- Try inserting an HDMI switch in between the AVR and the TV (or better yet add either an HDMI Dective Plus or Dr HDMI).
- Ensure there is proper ventilation around the AVR (at least 3-4" above the unit) and if enclosed in a cabinet, use a PC fan to exhaust the heated air out the back of the cabinet
- HDMI performance can also vary between the different HDMI input jacks due to quirks of circuit board design so be sure to try each of the other HDMI inputs as one may work better than another
- If you are having a video issue, try setting the "Resolution" setting to the resolution of the TV(eg. 1080p) rather than using the "Auto" setting.
- Try inserting the Dr. HDMI between the AVR and the TV/PJ.
