SHARP LC-32CHG6021K 'Wireless'? Remote Control.

ThisIsWeird

The remote control with the TV is a bit tatty, battery cover missing, that sort of stuff - tho' it works.

Took it apart for a clean and realised it had no IR LED. Then saw that it had what appeared to be an antenna etched into the PCB.

That was a new one to me.

Q - does this TV need a specific remote control, or will/should all Sharp TVs with 'wifi' remotes work, does anyone know?

Thanks.

Infraed is invisible to the human eye so even if it had an LED you wouldn't see anything anyway.  You can point it at a camera (on a phone maybe) and be able to see the light.

Failing that the TV remote may use Bluetooth.

Wireless remotes are a thing, they work by radio signal rather that IR (or ultrasound if you can remember that far back) it means you don't have to point them directly at the TV or whatever device it controls.
They are often on the same 2.4ghz frequency as wifi.

The Jukebox in my local has a wireless/radio remote control.

As for a replacement just use "sharp lc-32chg6021k remote" in google.
Oh go on then here's one, there are others whic may have a better price: https://www.remote-controls-shop.co.uk/catalogue/sharp/LC32CHG6021K/

It could well be Bluetooth - good call.

Pretty certain it ain't IR as no physical LED present, and no 'lens' cover on the remote. It must use 'radio' of some description.

Thanks - but the tele only cost £15 :-)

Just curious about the type of signal used, but also if this type of Sharp remote will work on all such receivers?

There's a couple of sellers on eBay with them at around a £enner each - seems very fair. Slightly different model numbers, tho'.

You could try some of the apps for Android/Apple but having tried this route for an old TV it can be frustrating or simply not work at all. Some work via Bluetooth, others by a common WiFi link. There's even a few that work with those odd phones that have IR blasters in them (Redmi? not relevant to you).

Thanks.

Seems they are indeed 'RF'. I ordered a new replacement on eBay - £11. Can't complain.

Not sure this wee TV is App-controllable, but our new Samsung seemingly is - and it already comes with two remotes :-(

I remember a few years ago samsung bringing out tvs with rf remotes , think the idea behind it was to overcome the problem when there is a bright light shining on the telly ir remotes would refuse to work.

And it saves on the embarrassing 'pointing and shaking' of the remote at the TV, as if the 'flick' added some extra woof to the signal...

Samsung have used minimalist RF remotes for many years (fairly sure they are bluetooth as they have to be paired to the TV, and There Can Only Be One! (as Christopher Lambert said..). they are brilliant- no need to aim at the TV, mine works in my lap or I can just press the required button as soon as I pick it up without the precision aiming.

I have a humax recorder as well, and the remote needs a telescopic sight to get it to work!

The Samsung will also respond to an infra red legacy remote or generic infra red remote with Samsung codes (it came with one with a full complement of buttons on, the RF one is limited), I bet the Sharp will too. (to a Sharp one I mean )

It would be interesting to see if it also has the IR receiver, then, but the new RF remote - or 'BT' - hopefully on its way.

Thanks for all your help, Facade :-)
