LE26R41 blacks out intermittently

[dkayuk]

Hi

I've noticed that in the last few days, my Samsung LE26R41 TV goes blank for a couple of seconds and then comes back.

I was watching BBC news this morning and this would happen every few minutes. I am using SCART right now (connected via NTL/Tivo) and my setup is:

NTL Digital Set-top box (the purple one!)
DVD player connected via Scart.
Tivo
Xbox 1 connected via component cable

Also, after the TV has been off for some time (eg while I am at work) and I then turn it on it will often shows nothing.

The "permanent" blackout went away when I did a cold reboot of the NTL settop box. Also, I haven't noticed any problems while watching DVDs.

Should I be worried? What's the next step? Switch cables? Ring NTL or Samsung? Or is my Tivo gone crazy?

Could it be the BBC signal?

The TV is about 9 months old and I haven't had any other problems with it.

thx

David
