I've got one of these Samsungs, and it is really a tragic design. While the picture quality itself is nice, real flat tube, colors and all, to lessen the dynamic contrast you've got to dial the brightness and contrast down so much that darker content on the screen fades into black. Yuck. I also had to resolder the Scart sockets several times, since they are only held down by the solder joints, no other means of stress relief. Last year, one of the speakers had malfunctions. I didn't bother fixing that, since most of the time I've got the TV and other stuff hooked up to my Surround sound system anyway.
On the upside, it wworks with both PAL and NTSC signals.
Geometry correction preview in service mode works with that TV only via RF connection. My older Grundig was able to access and preview service menu options for any source signal attached to it.
Once I move, this piece of shit will be thrown out, and I'll check local ads for another CRT TV.
