I can get all codes working except power on! I have set TV to UART, disabled anynet+ and set hotel power mode to power on which is all i can find from others on the internet. Anyone else got any suggestions? The spreadsheet really is a fantastic resource, just can't get this last one working.. My powershell that i am using #[Byte[]] $request = 0x08,0x22,0x00,0x00,0x00,0x01,0xD5 #off [Byte[]] $request = 0x08,0x22,0x00,0x00,0x00,0x02,0xD4 #on
#[Byte[]] $request = 0x08,0x22,0x0d,0x00,0x00,0x99,0x30 #power 2 #[Byte[]] $request = 0x08,0x22,0x01,0x00,0x00,0x08,0xCD #vol 50 #[Byte[]] $request = 0xAA,0x11,0xFE,0x01,0x01,0x11,0x13 $port= new-Object System.IO.Ports.SerialPort COM3,9600,None,8,one $port.Open() $ret = $port.Write($request, 0, $request.Count) $port.Close()

I want to replace my older UN60ES7500 with a new UN65KS9800FXZA. In my application it acts strictly as a monitor. I just use the ex link to turn it on and off via a Crestron system. Has Samsungs on/off protocol stayed the same so that I could do a simple swap without reprogramming expense? Thanks,
Chip

I did look at the link to the spread sheet in the very first post and that is the protocol I am using for my older tv. I contacted tech support and was told the protocol had changed. I've been waiting for it to show up in my email but all I was sent was a password reset. I guess I'll find out when the new tv is hung on the wall and connected up to Ex Link. It will work......or not.

I haven't had any issues with new samsungs. Hopefully it stays that way

Thanks. I'm hoping any difference in their latest protocol is only additions to what I have to cover additional features not on my current set. Like I said in my first post, I really only need to turn it on and off remotely. I can calibrate it with the supplied remote.

I have been using your code set for several years (THANK YOU!) but the new (Samsung 8000 & 9000 Series - 2016) models no longer allow direct navigation to Netflix or Amazon apps. Have you experienced this issue and if so do you have a work around?

Have you experienced this issue and if so do you have a work around? I don't typically use the built in apps on TVs so I can't say that I have run into the issue. I wonder if Samsung has an updated RS232 code list out there somewhere. If anyone finds something, I'd be happy to test the codes and modify the file.

I've been following this thread and actually got several codes working on my Sammy HLS6187W (which has an actual DB9 for the RS232 port). Odd thing is now, I'm not sure what happened but they stopped working and now I get a single byte response of 0xfd. I've tried factory resetting the TV, turning both PC and TV on/off, reseating the cable, writing the code in different languages (C# and Python). For the life of me I can't figure it out. I did go into the service menu and choose Debug for the RS232 mode. Any other suggestions?

The one time I had a TV stop responding to RS232 codes, it had locked up, and just needed to be pulled from the outlet. Maybe a Factory Reset has the same effect, but you never know.

I've repeated the results somehow, but still see the issue. I'm not sure whether the DBG/RS232 SEL option in the menu should be 'Debug' or 'RS232' mode. It has seemed to work with either but consistently fails as soon as the TV is turned off for decent length of time. If I user the serial control to power it back on within a few minutes it works, however once the TV has been off for a significant amount of time, it seems to lose all serial connectivity, even when I manually turn it on again. I'll have to give the pulling the power cord a shot, but hopefully that wouldn't be the final solution. Are there any other service menu settings that need to be performed to make this "stick"?

on the consumer tvs i have dealt with in the past few years, i haven't had to touch the service menu. next time i work on one i will go in and see what the settings are set to.

This one is quite old (2006) and actually has a straight up RS232 port. I'd tend to agree though it seemed to work on the default factory settings too, just not consistently. Have you ever had issue getting the serial port out of state or anything or having to do some kind of extra "stuff" on the port to get it into the right state? My code is very simple and I've implemented it in both C#.NET and Python. It's worth noting that while the TV is shut off and on, the computer is on 24-7.

One additional question is have you ever seen the need for any kind of "handshake" message before sending commands? Is there something that tells the TV to begin accepting commands? When it stops working the TV still responds to commands, just not with the expected 3 byte value. Sometimes one or two bytes and tends to be something like 0xfc or 0xfd.

Worked fine and at some moment for unknown reason my TV Samsung UE37C6000 stopped working via Ex-Link/RS232 port, while the controller program has not changed. I tried to change the port and swap the cable, performed TV factory reset, tried all possible setting at service menu with no result. TV doesn't accept the HEX commands, however when I change the port mode from UART to Debug I can see the response/logs from my TV at terminal window. Will let you know if I found solution

Im not sure if i missed it in the thread but are you able to show the checksum calculation formula it appears to be a completely different formula from commercial grade screens.
Thanks,
