Nothing on TV really scared or bothered me, I liked watching
Doctor Who (which was in my opinion much better in those days with
Jon Pertwee followed by
Tom Baker) and I loved other sci-fi like
Blake's 7, but none of frightened me in the slightest and neither did any children's TV. In fact when I was a young child my Nan and Grandad used to let me stop up late and watch late night horror films which were my favourite, I loved the Omen 1976, The Texas Chainsaw Massacre 1974, The Exorcist 1973 and many more (they would have been shown on TV a few years after release in those days), even these didn't frighten me in the slightest, in fact I often found them funny, but also engrossing. When my family got a VHS video recorder in around 1981 (I was still only 11 years old) I was able to record and watch horror movies all the time, by then however I was hooked on computers, but it didn't stop me using my computer while watching a horror movie on TV at the same time (my computer was downstairs in view of the main TV at the time, in 1980 I had a ZX80 followed by a ZX81).
I am however a strange one for not being afraid of things that most people would expect, for instance I have been to many paranormal locations since 1996 which started with Chingle Hall near Preston in the UK, which back then was allegedly the most haunted house in Great Britain. I have been in many places of activity and stood in the pitch dark, sometimes even alone and it doesn't bother me in the slightest and even when I experience paranormal activity I can remain totally calm. All the screaming on TV shows just makes me laugh (most paranormal TV shows are totally fake / grossly exaggerated by the way just to get viewers, paranormal activity doesn't happen all the time like on the shows, you have to be very patient and sadly so are many public investigations are also dodgy, I could tell you some stories from owners of locations when shows like Most Haunted visited detailing how they set things up).
Edit:
I've just thought of one children's TV programme that did actually frighten me that wasn't supposed to, but only because I was frightened about attending comprehensive school (and it turned out to be with good reason).
I first watched
Grange Hill when I was still at junior school (the children's TV soap started in 1978). I was very disturbed at what I might be in for and I asked my parents repeatedly questions like, "it's not really like that at senior school is it?" and they kept reassuring me with answers like "of course not" and "it's only pretend", but in reality comprehensive school was a lot like Grange Hill including many of the things the kids got up to and of course the bullying (I was sent to a normal school against repeated expert advice to send me to a special school).
Grange Hill later covered some very controversial subjects including bullying (a young girl tragically hung herself at home due to bullying at my school as this was mentioned in her suicide note and I used to get bullied constantly) and even drug use (yes I even I saw this at my school). The only things that weren't very realistic on Grange Hill was they weren't allowed to swear during children's TV and some of the violence had to be toned down (yes, it could be worse in real life).
I will leave you with a few bullying scenes and what can happen:
(Note: There was a few incidents of children being hit by cars that attended my school, in fact a girl in my class was sadly killed after school, so again realistic, things are somewhat safer these days with traffic calming measures around schools for instance.)
