Chromecast unavailable from standby (KD-55XD9305)

d_dave_1 — Sun, 18 Dec 2016 11:47:51 GMT

I would like to be able to wake up the TV from standby when I attempt to cast something to it, but this only works for a period of time after it has been switched off. Once this period has elapsed the TV is unavailable for casting and has to be switched on manually before the functionality is available.

I'm assuming that the Chromecast functionality is switched off by the TV after a period of time to save power, although I can wake the TV using the remote app so network functionality must be present.

Does anybody else suffer from this same issue or have a solution?

I guess I could just buy a Chromecast, does nobody else experience this?

Hi there

After a couple of hours the TV goes into a 'deep sleep' mode. So more than likely chromecast/googlecast services are suspended in this mode.

Solution is to turn the TV on before hand. If you're not that close to the TV, have you tried using Sony's "Video and TV Sideview" App ?

Ok, well that would explain it. The galling thing about this is that the expensive TV I bought can't even deliver the features of a £30 Chromecast device which would wake the TV from standby and play via HDMI.

For me this is something that should be fixed by Sony. Would you happen to know how I can raise it with them?

Hi there

I think the reason why the Chromecast device will 'wake' the TV up is simply because it is connected via HDMI and using a protocol called HDMI-CEC and its features. HDMI-CEC features can include "Auto TV ON" and "Auto Devices OFF"

Yes you are most probably right, but remember that the TV does indeed wake up from standby with the built-in chromecast for a period of time, it can wake-up via the IP remote software at any time so I see it as a fault that the chromecast becomes unavailable regardless of the technical reasons.

I agree that the chromecast being suspended in this way is a bug since it is contradictory to normal chromecast behaviour.

The cast device should remain reachable on the network and be able to wake the TV.

Actually with "Enable Remote Start" on the TV should always be visible by the apps supporting Chromecast in the mobile. Also because it seems there is a bug that prevents the TV to go in Deep Sleep when that option is On. Personally I have always seen my TV when that option is enabled. Then I disabled it because not going into deep sleep the TV consumes about 17-20W/h.

That's not the case. But some ZeroConf protocols can easily wake it up. If I for example enable Bonjour on my NAS, the TV goes into deep sleep and is woken up again several seconds later. So the TV toggles between deep and shallow sleep state every few seconds. If I disable Bonjour on the NAS, then the standby behavior is about the same as with remote start being disabled. Only difference is that deep sleep power consumption is a bit higher (~1W). So certain packets can still wake it up (similar to WoL).

Actually with "Enable Remote Start" on the TV should always be visible by the apps supporting Chromecast in the mobile.

If I remember it correctly, my the processor in the TV always woke up as soon as I unlocked my iPhone which probably was also triggered via Bonjour. So the TV was indeed visible for Chromecast clients. But if the TV stays in deep sleep which it also enters with remote start being enabled, then the TV won't be visible.

@Kuschelmonschter Now I don't remember well, but I think that in my case with Remote Start on, no matter if I didn't touch anything, each time I turned on the TV it woke up too fast, as if it wasn't sleeping. A couple of times foir testing it has been the first thing I did after the night. But sure, I have a MacBook always on (although sleeping) while at home and that may influence it as well.

Still, shouldn't the Google Cast "discovery" (when we touch the Chromecast icon in the phone's app) send a Bonjour signal or something similar? I mean, it should behave like when you unlock the iPhone. At the worst I have seen my TV or another (with Chromecast) appearing after a couple of seconds.

Or can it happen that if the TV is in deep sleep unlocking the iPhone it doesn't wake up? I am a bit confused.

This is how it looks like in my environment with remote start enabled:

At 23:00, the NAS shuts down for the night. You can see that the TV goes into deep sleep and the increased deep sleep power consumption.

Still, shouldn't the Google Cast "discovery" (when we touch the Chromecast icon in the phone's app) send a Bonjour signal or something similar? I mean, it should behave like when you unlock the iPhone. At the worst I have seen my TV or another (with Chromecast) appearing after a couple of seconds.

Sounds reasonable. I have no in-depth knowledge of Google Cast. But I think that the TV can explicitly be woken up when remote start is enabled. That's what it is good for. And I know for a fact that the TV goes into deep sleep with remote start being enabled.

Or can it happen that if the TV is in deep sleep unlocking the iPhone it doesn't wake up?

It does wake up. You understood correctly. But I would have to re-test the whole thing to be perfectly sure.

There is also the Sony Video & TV SideView mobile app which should be able to wake the TV from deep sleep when remote start is enabled.

What bothers me a bit about the image posted above is that deep sleep power consumption is sometimes 0.5W and sometimes 1W. Probably waking up only works with the 1W deep sleep. Wouldn't be the first thing that is totally broken on Sony...

Kuschelmonschter — Thu, 30 Nov 2017 06:03:41 GMT

I did several tests now...

In my case "Remote start" does not prevent deep sleep. Several devices in the network could however very well permanently keep it alive, like for example my NAS with Bonjour being enabled.

The TV mostly wakes up as soon as I unlock my iPhone. And if not, a Chromecast client like the YouTube app for example takes care of it. Sometimes I have to kill YouTube and restart it in order to wake the TV up.

Also at 5 in the morning, when my girlfriend started to read the newspaper on her Android via Chrome browser, the TV woke up and did not go to sleep anymore until she locked the phone again.

The waking up looks a bit flaky (like everything on the Sony), but it works in principle.

I am still having an eye on it whether the TV gets into a state from which I can't wake it up via network device.

This never works for me either. I've had to go and buy a Chromecast to plug into the HDMI port instead of just using the built in Cast function of the Android TV. Very annoying for an expensive TV.

I hope someone at Sony picks this up and fixes it.

@simhunte Do you mean that you never see the TV from an app when it is in standby (thus you can't wake it up), or you never see the TV at all? Which TV model anyway? If it is an Android TV there should be little differences from the added Chromecast and the one embedded in the television.

Unless, but only for the case when people don't see the TV at all, the TV is connected by ethernet cable, and the router doesn't make a single subnet WiFi+Ethernet. In that case there might be routing between the two and the Google cast packets may not get routed.

@Kuschelmonschter I have checked your posts. I believe at this point is also depends on each one's LAN. Sure, I have no tools to verify the Remote Start behaviour in my environment, in general the feeling was that there was no deep sleep when I turned on the TV. This before the last factory reset. Then something messed up with the net interfaces, that do not wake up before a minute (I believe I fixed it enabling the WiFi even when no connection is available).

It never appears on standby but usually (not always) appears when the TV is turned on.

Even when turned it and visible casting from Netflix often fails. But it works fine on the Chromecast device plugged into hdmi.

The implementation just seems shoddy and needs fixed.

I don't know. Maybe try to delete the "Google Cast" data. You should find it in the apps list. I had the inverse problem: it worked via TV but not with my kitchen's Chromecast. I did a reset to factory settings of the Chromecast and it much improved (although I must say that lately the device feels like a piece fo junk. It keeps losing the connection, with the video playing by iteself but no controls working on the phone).
