We have two clients that are having the same issue. Both clients have Crestron Systems, One has a DM 8x8 with all 4K cards and room boxes, the other has a 16x16 with standard 1080P cards and Room boxes. The customer that has the 8X8 has only one Samsung TV and cannot control the TV ON/OFF using Crestron. The customer that has the 16x16 has 12 Samsung TV's and is having issues with one not being controlled by Crestron.

Both systems have been working for years, the 8x8 system was upgraded 2+ years ago and the TV was installed at that time, System had been working fine until a couple weeks ago. 16x16 system was installed 5+ years ago and hasn't been touched and all other TV's are working in that house.

Both TV's respond to the OEM remote.

I don't do Crestron so I have some probably ignorant questions. I hope I can point in a useful direction.

What happened a couple of weeks ago?

What does Crestron say about this? What information would you provide to them that you haven't provided here?

Does "controlled by Crestron" mean a Crestron component sends IR signals? If so, it sounds like it's important that the OEM remote works.

If IP control, the OEM remote's ability to control shouldn't matter. And I don't know of any Samsungs with RS232 control, so I suppose that's not it.

Are any of the TVs connected to the internet? Have any updates of anything happened around the time the problem started? Are the same modules being used to control each and every TV? Is there such a thing as updates of modules?
A good answer is easier with a clear question giving the make and model of everything.

I'm not sure but a couple weeks ago only applies to one of the houses, the other house this has been happening for a while
What does Crestron say about this? What information would you provide to them that you haven't provided here? I haven't contacted them yet since I haven't been able to get to site to troubleshoot. Only information I would provide them are the troubleshooting steps (see below)

Does "controlled by Crestron" mean a Crestron component sends IR signals? If so, it sounds like it's important that the OEM remote works. Yes a Crestron component is sending the IR signals. The house with the 16x16 we tried multiple different IR buds and room controllers (with a room controller that worked on another TV) and no luck with the problem TV.

If IP control, the OEM remote's ability to control shouldn't matter. And I don't know of any Samsungs with RS232 control, so I suppose that's not it.

Are any of the TVs connected to the internet? Have any updates of anything happened around the time the problem started? Are the same modules being used to control each and every TV? Is there such a thing as updates of modules? The house with the 8x8 his TV may be connected to the internet, I'm not sure as he likes to adjust stuff, the house with the 16x16 No the TV is not connected to the internet. Yes the same module (IR Driver) is used to control all 13 TV's. No the module cannot be updated unless I modify the module in the program (which hasn't been done)

Not sure what you mean, the IR receiver on the TVs work as the TV responds to the OEM remote. If you mean the IR out of the room box doesn't work, this may be possible however we moved a room box from another room (which is working) and connected it to the problem TV and the same issue arises where Video will be displayed (if the TV is on) but control of the TV is not available through Crestron.

I have had similar experiences with the same equipment. 2 weeks ago I had a Samsung 78" stop responding out of no where. Rebooted RMC, swapped RMC, still nothing. Rebooted the processor and it started working again.

Had another one where the actual IR emitter failed. Swapped in a new emitter and everything worked again.

Oh and on another note, I have had samsung displays stop responding to all ir commands except power on/off from a factory remote. Rebooting the display fixed this.

I'd assume you swapped out emitter and cycled power on RMC, TV, and processor?

My guess is a power cycle of the TV will solve both issues. We've had issues with 232 control crop up over the past two years. Some due to firmware, some due to incompatibilities with using Crestron IR ports as one-way serial. Our solution has been to convert to IR or use CEC. Both methods have worked fine since. If you are using IR, I would suggest you use the 'Samsung UN Series' IR module in the database. Otherwise, you have DM in both jobs so just use CEC.

ive had this issue with sonys and samsungs. omebody else started a topic where they said they had this issue with sony. this is what i responded on that one

I’ve been having that issue with Sony and Samsung TVs where they won’t turn on after being off for while. But it’s only when trying to use a discrete on command. If you use a remote with a toggle power or push the button on the tv it will turn on then the discrete commands will work for a while. The Sony’s seem to be an issue with android os. When it locks up, after I power it up it does that android start up animation. Very frustrating.

Have you confirmed the room box is actually online? If not, that would explain why control isn't working. That could be caused by a defective cable, connector, room box, or output card.

FYI, a room box can be "offline" (i.e., not communicating with the processor), yet still pass video. So, the presence of a picture doesn't mean everything else is good.

This obviously isn't the problem with the TV not being controlled by Crestron, and it could simply be a coincidence that both problems occurred around the same time.
