I have a Samsung EH5000 TV which has suddenly developed a strange problem with its 2 HDMI ports. I have three devices which when connected to the TV it reports no signal on the HDMI port. These three are: a Virginmedia non-recordable TIVO box, a laptop connected by HDMI and a Google chromecast. However, there are two devices which work fine via HDMI: these are an Amazon Firestick and an Apple TV. This clearly signals that the HDMI ports are not completely broken because they work fine with these devices. My research online indicates this could be a handshake problem and what I hope is that it could be remedied by making changes within possibly within the service menu of the Samsung TV. I have found 15 settings related to HDMI in there. Hope you can help.
Yes, these are not new devices. Everything was working perfectly and then all of a sudden it went as described above.
I have only looked at the settings withouth changing anything. I've already tried the solution you suggested because it was one of the first things I read about online as an answer to the problem. In fact, I've tried it several times in the way you described with the 10-minute method. It didn't work.
Yes I've done several factory resets already. I've tried every obvious thing already.
1) Factory resetting
2) TV off for ten minutes + power
3) Swapping HDMI cables over
4) Trying different ports
5) Testing devices on another TV to make sure they aren't faulty (they aren't)
This is what I've done so far
HDMI Hot plug > Disable
But I dont' see the second option you mentioned. I do see HOTPLUG SWITCHING. Is that the same thing>
DVI/HDMI sound: Auto
HDMI HOT PLUG: Disable
HOT PLUG SWITCHING: Boot
HOT PLUG DURATION: 1200ms
CLK TERM DURATION: 12000ms
HDMI FLT CNT SIG: 100ms
HDMI FLT CNT LOS: 100ms
UNSTABLE BAN CNT: 500ms
HDMI ERR CNT: 0
HDMI ROBIN: ON
HDMI CALLBACK: OFF
HDMI CTS THLD: 8
HDMI CTS CNT1: 0
HDMI EQ: AUTO
HDMI WRITE TYPE: Combine
HDMI Switch: None
Sorry that didn't help. The other option in switching was called Source.
The options are SIL 9287 and TMDS461
Some additional information for you.
If I turn on two of the devices that don't work (Google chromecast and Virginmedia box) the boot-up messages of those devices does appear on the screen through HDMI. Once that phase is finished the HDMI shows no signal. Does that mean anything to you or change anything about your previous answer?
Is there any possibility that a HDMI booster could rectify the situation?
I totally understand that your diagnosis could be the right one and that if I pursue this I might be wasting my time.
Nevertheless, I just want to exhaust every possibility. Within the Samsung service menu there is an option marked Expert that is grayed out. Do you know what's in that menu and is it possible to access it? I have learned how to use Factory and 3XSpeed to access the extended menu but that doesn't open Expert. Any ideas on that?
Ah ok that's clear.
One more thing sorry. The devices that were working have stopped working and this is a shame because I have a Virginmedia engineer coming today to check things. If I can't show him that some devices work he'll just think it's all completely broken and there's nothing to do. Could that have been related to any of the changes we made yesterday in the service menu?
