Sony HT-Xt1 intermittent picture drop-out via HDMI

I am experiencing random picture and sound drop outs while watching my Sony Bravia KDL-46XBR4 TV via my Sony Ht-XT1 soundbar.

The screen will go black occassionally (with audio drop outs) while watching TV. I have an Apple TV 4th Gen, LG Blu-Ray player and Motorola PVR connected to it via HDMI. When playing music via Bluetooth, there are no issues. I have tried turning off HDMI control on the TV and soundbar and it doesn't seem to help. I've tried changing the HDMI cable to no avail, although I used an older cable that I had lying around. I thought maybe the devices were overheating, but I've put fans on the devices---it didn't change anything.

Any ideas what the issue could possibly be?

Potential problems include bad HDMI cables (not spec'd to the current signal), HDMI handshaking issues, or trying to run an unspported signal through the sound bar. Since you haven't specified when you are having drop outs, that's the best starting point I could offer.

There's no rhyme or reason to the drop outs. It just happens occassionally when I'm watching something through the soundbar. It happens with my connected Apple TV and cable box, and I've tried different HDMI inputs on the TV. It still does it. I guess I could try a new cable, but I've already swapped the cable with a spare at home and it didn't help. Turning of HDMI Control didn't seem to help, either.

Re: Sony HT-Xt1 intermittent picture drop-out via HDMI

Let's try to be methodical and specific. Your HDMI cable is what brand, is it high speed, and when did you buy it? Is HDMI CEC turned on or off? What model LG BD player, cable box, and DVR is connected? Are there still drop outs once you disconnect the Apple TV and DVR? What was being displayed when the black outs occur (streaming content, the GUI, etc.) Did you try running only one device at a time connected to the soundbar and TV to try to identify the offending unit(s). What output settings are you using on the Apple TV's output? I will assume it's outputting a 1080p 30fps or 60 fps signal? The TV doesn't support much else above that. If you disconnect these devices from the soundbar and run them connected directly to the TV, do you still get blackouts?

I can tell you there is a reason this is happening although it doesn't make sense to you. If you trying to pass a HDCP 2.2 signal thru your soundbar, black outs would be what you may get. It isn't compliant so that is likely your problem.

Try to use a troubleshooting approach. Isolated the devices which do and do not cause drop outs with the soundbar (one at a time). For the items that do cause drop outs, see if they remain problematic when connected directly to the TV. Stuff like that would be helpful to isolate the cause and suggest solutions.
