Samsung CS-29M20SPQ raster are shifted to right-upper corner.
In my Samsung CS-29M20SPQ S61B chassis ( Schematic Diagrams - http://downloadcenter.samsung.com/downloadfile/ContentsFile.aspx?CDSite=ITSELF&CttFileID=288242&CDCttType=SM%20%20%20&ModelType=C&ModelName=CS29M20SPNSKLG&VPath=SM/
200504/20050407144315562_s61a_sdiag.pdf ) raster are shifted to right-upper corner so the left and bottom arise blank space approximately 1cm 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 (http://lill.front.ru/FTP/w_o_SCAN.PNG) . 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 (http://lill.front.ru/FTP/OVERSCAN.PNG ). I compare input circuit from CS-29M20SPQ ( http://lill.front.ru/FTP/SAMSUNG.PNG ) with Micronas VSP
9402A Data Sheet reference circuit ( http://lill.front.ru/FTP/VSP_9402A.PNG ). Samsung very complicate input circuit. May be that is radix malarum ( the root of all evil ). Whether rational that complication.
I make apology for my bad English :-( .

There is three numbers are used with model to model. It will differ according to chassis fitted with it. All chassis number will be the same, but the layout will have some difference, and company does it meant for advanced performance. If you wish to get some details; check the site linked here.

well I thought they had one there but it looks like they only have other chassis # and I have been looking to try and find your chassis # but the only ones ask for money to get it , but I have found some codes and remedy's for your chassi , you had a 5 blinking code which the diagnosis would be this
5 times, Diagnosis: White balance failure (Not balanced) Possible causes: Video out (IC7101, 7201, 7301) is faulty (CR, CG, CB board), CRT drive (IC309) is faulty (A board), G2 is improperly adjusted. Symptoms of the problem: No raster is generated, CRT cathode current detection reference pulse output is small.
if the blink code is now different then let me know what it is and i'll give you that diagnosis
this sympton is characterized by the presence of red, cyan, green, magenta, blue or yellow colour in a supposedly plain white raster. proper colour reproduction cannot be expected if the raster is coloured.
this symptom is caused by a poor white balance adjustment of by a trouble in the CRT, colour amplifier, color demodulation or colour output circuits.
if the raster has a tint of red or cyan, check the R-Y output circuits and the first grid, second grid and cathode circuits of the red electron gun.
but if you dont know anything about this, just bring it to a qualified service technician. good luck!
