I would like to hear from anyone who owns a Panasonic PV-1730 VCR. I just bought one. It had features I wanted and looked pretty good in the store. However, at home I having trouble with the color level. The tapes playback at a significantly higher color level than the tuner. When I feed it into my Panasonic TV, I cannot leave it on VIR. I have had two of them now, so it is not an indiviudal unit problem. For fun I got hold of the service manual and noticed that there is a supplement that documents a modification to the chroma board (it is actually a little board that piggy backs on top of the main chroma board). It is not clear to me if this mod just brings the schematics up to date with the final production model, or represents a fix not made in some production models. The Panasonic distributor in Atlanta can shed no light without taking my unit apart and seeing if the mod is there. Anyway, I am suspicious of the chroma mod and think it may be related to my problem. If you have a 1730 please drop me a line.

I am experiencing the same visuals on my pv1730. However, I have approximately the same color thing on my SONY 2700. This leads me to deciding that this is considered "normal" for VCR playback modes. The interesting thing is that the SONY VTX-1000R Tuner and the 1730/2700 in tuner modes are all approximately equal (good to great) in picture values. Have you also noticed the differences in color saturation in the signals from the three major networks? > Anyway, I am suspicious of the chroma mod and think it may > be related to my problem. The earlier information makes me suspect that the "chroma mod" is not the culprit, unless SONY's and PANASONIC's circuit boards are made by the same company (not completely out of the question with all of the product nepotism that goes on in Japan).
