If we power the TV on using the remote, it turns on and shows the source on HDMI 1 with no issue, so it seems that the ex-link Power On command is sending it into some weird mode?Īnyways, the manual doesn't even mention Ex-Link but it does talk about MDC and Video Wall functionality, so I figure that's the protocol we should be working with, but I'm at a loss as to how to enable it on the TV.

Switching source using remote doesn't work either. The device is connected on HDMI 1, and sending the command to switch to HDMI 1 does nothing. Problem is, when I send Power On, it does turn on, but I'm getting no picture, just a 'No Signal' error screen. However, If I try sending any commands using the MDC protocol, I'm getting no response at all.īut If I try ex-link protocol commands, it responds with, which is an 'OK' response in Ex-link. it's got the mini-jack in the back like the Ex-link TVs, but the manual says it uses the MDC protocol, and apparently the system menu has options for setting device ID. I've successfully been able to work with several other Samsung models, using either the Multiple Display Control (MDC) protocol or Ex-Link.

I've got a couple Samsung PH55H TVs at a remote site that I'm having problems with.
