Question:
I've already done a search on this and can see some other people have seen this already, but I haven't found a solution (that doesn't involve a new telly, anyway).
I just got a new Thomson 28" flatscreen (code has a 211 in it) from unbeatable and, while the tv reception is pretty poor anbd the remote is naff, the RGB on DVD's is pretty damned good for a 50Hz set so I was happy. Until I put on my R1 Die Hard and noticed these funny dark rolling bars following some parts of the image that had large brightness changes. I've tried R2 and R4 PAL DVD's and they've played flawlessly, but every R1 DVD has these bars.
Some people have said this is due to NTSC incompatibilities, but support for all NTSC modes is mentioned in the TV's specs. Everything used to play fine on the Sony 25" it's replacing and nothing else has changed apart from the telly. Do I have a knackered telly? I really can't be bothered trying to send it back, it's damned big and was a pain being delivered.
BTW, the player is a pioneer 454, scart is an IXOS chunky thing and this happens in both scart sockets. I think someone mentioned it was possible to force PAL60 to be used for ntsc on some Pioneer players?
Anyway, any opinions are appreciated.

Not sure from your description if this is it, but a common cause for rolling bars evident on NTSC but not PAL is crosstalk from the TV's tuner output. This can occur both inside the set and in the cables. As you already state you are using a supposedly 'good' cable, this puts the TV under suspicion.
The easiest way to test this is to either tune the TV into an empty channel (ie, one without a broadcast signal on it) or unplug its aerial - either way, so that it isn't showing any sort of picture other than the black and white noise 'raster'. Then put on an NTSC DVD and see if the symptoms have changed - if they are exactly the same, in ain't this. If the scrolling has gone, or is less visible etc., then it probably is.
Which then leaves you with a choice; theoretically it shouldn't be the IXOS cable, so the TV is suspect. Ideally, you would borrow another SCART cable of a different make to prove this. If it isn't the cable, you may choose to simply detune the TV as above whenever necessary, or you may want to get it seen to.
Thanks for that idea, I'll investigate that tomorrow. I've been meaning to try another scart (I've a couple of them in my bag 'o' leads) but seeing as this is the only "decent" scart I've got I wouldn't have thought it would be at fault, especially as it doesn't exhibit it in the old telly or with PAL... hmm...
I'll let you know what result I get unplugging the tuner.

Time to revive this thread...
Pulled the aerial out, no change. Pulled the other scart out, no change. Pulled things out of the power block, again, no change.
Next up was a different scart. One fully wired scart later, still evident banding.
Located a composite cable and wired that up to the front of the telly. Picture quality was noticeably fuzzier and at first I thought the problem had went away, but it just required a little effort to notice it as the picture was that much blurrier.
Eventually found my 454 manual and figured out how to change the output to always output PAL. Changed from auto to PAL and the problem is STILL there. Now I'm really confused.
Any more ideas, oh learned ones? Or is the telly at fault?
Cheers,
Kev
I have this same problem with my 454.
During normal playback horizontal light bars follow light sources on the screen.
It is really evident on the credits where light text against a dark background shows heavy banding.
I have tried PAL-NSTC-AUTO on the 454 with no luck. It seems to 'band' only throught the RGB output as the normal video output does not have the bars ( of course RGB is prefered for quality) .
Tried the same DVD, with the same connections, and RGB, in my old Samy 709 there is NO banding.
therefore it must be an issue with the 454.
???
my 454 was from Richer Sounds and was sold as multi-region.
:confused:
What baffles me is that the player was fine with the old Sony 25" I had a couple of weeks ago. Also, on mine I get the banding on RGB and S-Video scart, S-video regular cable and composite, albeit to differing levels as the sharpness decreases.
I can have a try with my dad's sammy 709 tonight, but didn't the sammy have some kind of Quasi-PAL which forced a compatible signal for all TV's?
Anyway, my moneys on the TV - I was told it was an end-of-line job and now I think I know why... do you think I'd have more luck going straight to Thomson or should I direct a whinge towards unbeatable?
Sorry the aerial thing didn't work. Maybe you could try tweaking the TV's brightness &/or contrast to minimise the effect.
Don't worry, every suggestion helps :)
Haven't got round to testing with my dads player yet, I'm using the problem as an excuse to study for my Exchange exam next week instead of just watching dvd's :rolleyes:
