When I film my TV screen, I get a "ceiling fan effect"

Is it due to a difference in the frame rate?

Please advise if anything can be done to suppress this effect?
 
What kind of TV set do you have?
PAL, NTSC, HDTV?

PAL has a frequency of 50 HZ, NTSC of around 60 HZ (actually 59.94 HZ) and HDTV I don't really know, depends on the resolution I suppose.

But some TVs have higher frequencies than their broadcasting standard, to avoid flicker.

Maybe your camera has a Shutter setting in the Menu, with which you can play and see how it works.
 
I have a PAL TV.
I filmed the TV screen using the 1289 X 720 60 fps HR setting

Your suggestion to try the SHUTTER setting sounded promising. I just happened to have it in front of me, set on "D" (whatever it means). I saw that the other options were B and C, maybe more, but by the time I walked to my TV set to try, the Xacti screen had shut itself off, and when I switched it on again, the SHUTTER menu had disappeared!

I scanned all the menus in vain trying to locate that SHUTTER menu, but could not find it...

Do you happen to know where it is?
 
I doubt that your camera is capable of setting your shutter to various settings, as it's a feature found mostly in semi professional (and upwards) cameras. You have to look into the manual for this.

And D, C and B don't seem to be that kind of settings, as shutter speed is more like 1/12, 1/25, 1/50, 1/60, 1/100, 1/125 and so on.

By the way, PAL has a resolution of 768/720x576 with 50 interlaced frames.
