Would have posted this in the remote side of town but it is a dead zone.

Need IR descretes for the 115" TCL display for an existing client. Lack of discrete control was a thing with TCL back in the day so I have avoided using them. But dude just had to have the biggest tv in town (thankful I am not stuck installing it).

Older RTI ID programmed system (T2X, XP6). Outgoing display is IR, basically just need on/off.

Any help would be appreciated.

I have one showing up for install tomorrow or Friday. Guy didn’t like the 2x2 video wall we installed due to the cross hatch after we explained it and he saw one at a bar and then signed off on it.
Not sure if they have 232 either, hoping it does.

Will pull the remote and do some testing when it shows up. Nstalling is going to blow as the video wall bottom of the TV’s were about 8’
There's no worse feeling than that millisecond you're sure you are going to die after leaning your chair back a little too far.

Thanks!
Currently nursing a sore shoulder from doing a 75” 2x2 video wall 15’ up in a bar last week.
Not fun.

Went out and took a look at this beast. Unless I am missing something, the remote appears to be exclusively bluetooth. The few TCL codes I had did not appear to do anything. Tried playing with CEC settings on connected gear and no dice.
Sigh...

Are you able to open Jp1 files on hifi-remote.com? See the link in the first post of this thread:

They usually have pronto hex available in the files in column.

Dunno, will try.

Also reminded me of something I forgot to try. Programming a cable/sat remote to control the TV and then learning the codes from it. Would at least get me a power command. Worst case I could set/clear flags based on that one command. Client has no interest in the on board streaming and would rather use their sat box and appletv via AVR.

Just been a long time since I had to fiddle with a display. I tend to supply gear I have solid discretes for.

Thanks!

I sent an email to TCL asking for some info on the tv and IR codes, this is what I got back:

Thank you for reaching out to us. We understand the importance of having IR codes for your TV when using a third-party remote control system.

Unfortunately, we do not recommend using third-party remote control systems or universal remotes with TCL TVs, as it is not guaranteed and may result in inconsistent performance. Additionally, the TV does not support IP control, meaning it cannot be operated via network-based IP commands.

So IP is out and they don't want to give out any sort of IR commands.

Thanks TCL! Huge help.
There is a reason I never spec their product.

I am not even sure if it has an IR receiver. Wasn't able to confirm one in any of the usual locations. Can't see the back of the display to look for an IR input jack, client didn't have the manual for the tv either.
The remote does not output any IR (tried my learner) and it shows as a connected BT device in the display's menu.

Oh yeah, I forgot to mention, it is causing HDCP issues with the Directv receiver, pic flashing in/out, getting "please switch to component cables" on message on others. The 4k appletv is perfectly happy.

Always something with this industry.

I think we are going to hang this one on Monday or Tuesday, I will am taking my arsenal of ir capture/test stuff. Will see if I can find something for this darn thing. Would love to open it up at the shop and test but the crate it comes in would need to go back into to transport to job site. So job site testing it is.

The TCL Google tvs respond to the same IR codes as Fire Tv's use. Just try all RCA codes to find a response initially.

This is a DTV issue, hey are desperately trying to get out of the STB world and into an App only environment. To this end over the last few years they have slowly rolled out an update that "Ups" the required current on the TMDS feeds (this is provided by the Sink device), jobs that worked perfect will now display issues (not always the same ones). So, when you call for support and tell them that you cannot use component they suggest a streaming device.

Try a shorter & fatter HDMI cable, or "reclocking" splitter standby (it does not recheck, but many splitters will provide a higher level of current.

Thanks Brent.
The Directv receiver is colocated with and fed through an AVR (current Marantz Cinema series), I don't think the cable can get much shorter. Client previously had one of the 8k Sony displays at this location. The new display introduced this issue.

Sigh, we are doing HDMI splitters again?

Also: One major holdup/issue with Directv (and cable companies) wanting to go to a streaming model is kinda stupid simple. Many older (and some younger) people want number buttons. Everybody is moving away from them and that frustrates the heck out of many.

What he said.
I have recently updated all of the DTV equipment at our owners house simply because he knows the channels numbers and they provide easy access to what ha wants to watch.

Ok, tv is up, control sucks. Power toggle only, no discrete inputs.

Home button and Netflix buttons power it on. I tested a slew of rca and tcl codes and none of the discrètes worked for power or input. I did turn off all inputs except 1 and set to power on to last used input. Setup control with URC system and seemed to work ok for now. Didn’t have a ton of time to really dig in the control side but it’s up and working for now.

Is the IR receiver center bottom of the display (where the logo and buttons are)?
And did you learn the power command from the remote or just find some random TCL code that worked?

RTI's IR database is pretty shy on TCL commands.
