I have a Samsung Smart TV (UN50NU6950FXZA) which just started
acting up. When powering on it no longer defaults to the HDMI input
coming from the cable DVR box. The TV now defaults to the Samsung
TV Plus app*, which a set of free TV channels provided by Samsung. I
have to manually switch the source to HDMI if I turn the TV on.

*Well, it sort of defaults to the TV plus app. It shows the TV Plus logo in
the upper corner and it displays the name/number of the channel that
it was last tuned to, but it doesn't actually display the channel. The
screen just goes blank after a couple of seconds. If I select a different
channel, it will then display it. When it first powers on it's kind of in a
TV Plus-esque limbo.

I called Samsung and they tried to blame my cable provider's equipment.
When I told them that I tried both a different HDMI cable and even a
different cable set-top box, they were stuck. The only other suggestion
they had was to try a factory reset. Great, now I'll have to reload all my
apps, hoping I remember what password I used years ago, etc.

I'm really just venting but also sort of hoping that someone has other
suggestions to try before I do the factory reset. No, there is no "Default
Power On Source" that needs to be selected in the settings. If there is a
signal at the HDMI port, it's supposed to default to that.

I found a possible solution but I can't test it tonight. I need to be careful
because it can apparently turn my TV into a 50" brick.

It seems that there may be a service menu built into the TV where you can
actually force the default power on source to be an HDMI port.

Just a thought - is the TV picking up a wifi source that wasn't
there - before this problem started ?
I'd probably do a little trial & error before trying the service
menu .. maybe disable the wifi ; shut everything down & re-start
? the idea being that it will revert to HDMI as default ?
Good luck - let us know how it turns out.

My TV is hardwired via ethernet to the cable modem/router.

It doesn't matter if the modem/router is on or off or if the ethernet
cable is connected or not. It still defaults to showing the name/number
of the last TV+ station that was chosen and then the TV goes blank.

As a reminder, once the TV goes blank, I either need to switch the source
to the Cable box HDMI port or use the remote to go up or down one TV+ channel
in order to get a picture or sound. The only difference when the modem/router
is off or the ethernet cable is disconnected is that the TV, obviously, will not
display the chosen channel but it will at that point tell me the network is not
connected.

I have also disconnected all cables except for power and the cable box HDMI
cable. It still (tries to) power on to TV+.

My Samsung TV remembers its most recent input and will return to it
when you turn it on. This seems like the most logical way for it to
work.

The TV has a screen where you can set it to automatically install
software updates, or to check manually for updates. Maybe there's a new
update that will fix a known problem.

I wouldn't hesitate much to do the factory reset. I only have a couple
of apps that require passwords and I know them.

Many "smart" TV's support CEC device control. If enabled on the
TV, it will automatically switch HDMI ports if or when the device
attached to that port is powered on or changes state.

There is usually a menu item on the TV to disable CEC control either
globally or on a per-HDMI-port basis.

This is usually the cause of unexpected HDMI port switches by the TV.

Interesting! My TV does, in fact, have a setting to globally turn CEC
on/off. It's actually turned on now, but I don't have any devices
permanently connected to it to control. I've seen the setting before
but I didn't know what it did.

Samsung's version of CEC is Anynet+.

It was/is set to On. Turning it off made no difference so I turned it back on.

All the basic troubleshooting steps have been taken.

- Unplugged the TV
- Rebooted the cable box
- Swapped out the cable box
- Swapped out the HDMI cable
- Turned off the cable modem/router
- Removed all cables to the TV except for power and the HDMI cable from

John T.

There is no specific setting to disable the TV's WiFi. In the Network Settings window
you choose Wireless or Wired. If you choose Wireless, you see the standard list
of nearby WiFi networks. Choose a network and it asks for a password. If you
chose Wired, it just connects.

When I choose Wireless, it wants me to choose a network and when I choose mine,
it wants a password. That tells me that the TV is not connected to any WiFi network
at this time, just the wired network.
