In my Samsung CS-29M20SPQ S61B chassis raster are shifted to right-upper corner so the left and bottom arise blank space approximately 2cm width through all video input ( SCART-RGB/YCbCr/YPbPr, S-Video, Composite ) except for signal from inner tuner. It mostly well-marked when DVD playback UEMT ( Universal Electronic Measuring Table -
Russion analog Indian Head or Lion Head ) generated by MATHLAB and stored on CD as .jpg pictures with resolution from 640X480 to 1024x768. I supposed that it glitch DVD's FW module responsible for pictures output. Then i record .mpg clip composed from UEMT.bmp - selfsame outcome. Then i attach Saphire Radeon 9600 Pro S-Video output to TV's S-Video input and examine UEMT.bmp immediately from my computer - selfsame outcome. Using ATI Catalyst Control Center ( 2007.6320.2246.38712 ) i shift picture down as much as possible and enlarge picture size to the maximum - bottom blank space is all the same.

But if use OVERSCAN mode in Catalyst Control Center - bottom blank space is disappear, but picture's borders are exceed visible area and picture are truncated
.
I compare input circuit from CS-29M20SPQ



vs Micronas VSP 9402A Data Sheet reference circuit

.

Samsung very complicate input circuit. May be that is radix malarum ( the root of all evil ). Whether rational that complication.

Menu deflections sets in Servise menu altered only for all inputs at once. So if i tune centering at S-Video (for example ) centering from antenna's input will lost.
O.K. - i decide use DVD and computer only NTSC format, but Service menu haven't Deflection NTSC menu item although by Alignment and Adjustments this menu item must be. I suppose that menu item may be activated by option byte.
Anyone can explane destination one for me?
I make apology for my bad English Sad .
It's my Service menu
