after rooting, tv restart without reason

[Stephan296]

Hello,

I have root my samsung F serie, i see 2 things.
My screen quality is bad (the colors)
Also my tv restarts without any reason when i watching tv.
Can i find somewhere a log or something?

My screen quality is bad (the colors)

You probably accessed service menu which resets picture settings to (ugly) factory defaults. Root can NOT affect "screen quality" in NO WAY

Also my tv restarts without any reason when i watching tv.

Disable watchdog.

Thanks for your quick reply!
I dont have access the service menu at my samsung.
I block the updates in my router.
But i get also the message that there will be a smarthub update at 28-10-2015.
Is there danger for my root?

Ahhh there WILL be an update?
I don't think Samsung will give the choice anyway, so let's wait and see...

Maybe there is another url i have to block?

[zoelechat]

Maybe, but no idea which one(s)

[Stephan296]

maybe is a network scanner a option to see wich url's the samsung tv use.

If you use router to block urls, I guess you're also able to know which ones are accessed
