Last Samsung TV I bought was like 7 years ago. It was a HD Tube set that hade a very narrow, space saving yoke.
That design didn’t really help with the focus of the widescreen at all.
The overall picture itself was incredible but the picture dynamics sucked bad.
Returned two completely faulty ones before I went for the incredible Sony 34in widescreen HD tube set.
I know that set. I worked on a few of them. EVERY one of those “pseudo flat panel” 30” or so “thin tube” sets had linearity problems. Many had voltage regulation problems, solvable by replacing one or 2 resistors in the B+ trim ckt. BUT the linearity problem was NOT really solvable, without a new yoke....and it my have been a “bonded yoke set”....meaning part of the CRT.
