Another 21CT55 Operational
[QUOTE=Tomcomm; I hope you get the Wizard of Oz for subjective evaluation of your 21CT55 picture quality and suggest also getting the " Digital Video Evaluation" DVD's test patterns for critical setup and objective PQ evaluation. Looking forward for your full-screen width, no room light, full computer monitor posted JPGs. I know what the 21CT55's are capable of so lotsa luck finishing this one off...........Tom[/QUOTE]
Your first screen shots presented full monitor size, with total room blackout are quite good, the OZ clips are most impressive. The computer generated cartoons showed near-saturated colors with none of the natural flesh facial graduation of the OZ closeups. The OZ's subtle color graduations is where our 21CT55's low level chroma demodulation and matrixing is so apparent. Is your 21AXP22A possibly a different phosphor then the non A ? Looking forward for more "natural" screen shots....Tom |

I do have an AVIA home theater test pattern DVD from 1999 if those patterns are of any interest. My cheap camera tends to produce pictures that look more red/blue than what I see, so I turned up the green a bit until the gray scale pictures looked gray before I shot those pictures.

The Oz pictures were all from a DVD using the DVD video out feeding a BT AM-60-550B on channel 4 to the 21CT55 tuner. The Nemo pictures were from satellite using a video input to the DVD then through the BT to the tuner. I found my set matched the RCA schematic in most places but matched the Sams in others. I did try the Sams wiring for the contrast control but it seemed to make the picture softer. I like the sharper image I get with the RCA wiring. I did rewire the CTC-3 chassis to match the Sams after several not so good attempts to converge it. I got a better result with the Sams CTC-3 wiring, so I'm keeping it. With the horizontal width switch at maximum the image just barely filled the screen. I added several mica caps in series, measuring 74 pF, across the width coil and that gave me enough width to have overscan at the middle width switch setting.

That is one good looking 21CT55. Possibly the best performing of the early color TVs.

Thanks, it turned out better than I had hoped. The knowledge the members have put in these forums really helped my restoration.
