Sony remote (and replacement) not working

[SteveStacey]

Hi

The remote for my Sony 49” 2019 LED TV doesn’t function. (RMF TX310E) I bought a replacement and that doesn’t work either. No response from any of buttons, unable to switch from Sky Q hdmi to TV. Firestick etc.  

I’ve done soft reset and TV comes back on but unable to use remote. 

Tried multiple new batteries.

Thanks

Hi @SteveStacey   

The starting point for any request for help is the full model number of your TV. It will start with KD or XR. Unless something is blocking the IR receiver on the TV it sounds like you may have a physical problem which can only be diagnosed by Sony themselves. I would try Sony Support. You will need your TV's serial number, receipt etc.

As a quick check to see if the remote is trying to send a signal, point the remote into a mobile phone camera, you should be able to see the signal.

There are also plenty of Sony Remote Apps available for IOS and Android.

Thanks for swift response. More info:

It’s a KD49XF9005. Never use the TV for YouView, apps, as only ever watch Sky Q (hdmi 2) and Firestick (hdmi 1) Also have Sonos Arc connected via E arc,

Had this setup for a few years without problem. A few weeks ago, realised original remote was malfunctioning. (Wanted to use Firestick) Checked battery compartment and could see batteries had discharged to connectors. Cleaned up, replaced batteries and it was good for a few weeks b4 failing again.

Replaced batteries again and eventually ordered replacement remote on EBay.

It’s a funny one. Almost like the original remote is crocked and it won’t let me connect the new one. Problem is I can’t get into TV to check settings, pair new remote.

When I did the soft TV reset,  it immediately went back to Sky mode.

V bizarre.

Regards.

Hi @SteveStacey 

Any signal showing with the mobile phone camera? Perhaps you have got a “eBay” remote.

Sorry, I missed bit about pointing remote at phone camera. How do I do that exactly? In your image, camera screen looks dark.

Hi @SteveStacey   Simply point your remote towards your camera lens and press a button. That large black thing is the remote end that normally points towards the TV. The light showing is the infra red signal that becomes visible on a mobile camera. My IR remote is a different shape to yours (RMT-TX440E).

Thanks. I’m not normally a technophobe but struggling with this. Am I meant to be pointing remote at the lenses on rear of iPhone 11 camera? If so, can’t see any signal being projected. However, difficult to know if I’ve aligned it correctly.

Hi @SteveStacey   Yes, using the lens on the back of your iPhone, make sure that it is the end of the remote that normally points towards the TV and far enough away to show the entire end. If you don't see a light (IR) when you press a button, that means the remote is definitely not working (dud). No need to take an image, I did to show you what an IR signal looks like (iPhone 15 Pro rear camera, not the one that you use for selfies!).

“Far enough away to show the entire end”. Can you explain this please. Thanks.
