Summary

New to this year's core line is a DVD Component Input on all 30 and 60 Series sets. For the customer who desires a larger screen TV but is not concerned with Dual Tuner PIP, the 30 Series is decidedly the answer. We remain equally aggressive as the 60 Series with our 30 Series models inputs ~ each model comes with a DVD Component Input, an S-Video Input, dual rear AV Inputs with a third Front AV Input, and an audio output.

Has all the input options and the exact same tube and chassis as D-Series models, but in a smaller footprint thanks to bottom-mounted rather than side-mounted speakers.

Notes

Settings for red push are saved separately for different inputs and picture modes. To disable for all combinations, see full instructions under Mods & Repair Guides.

While the suffix to the serial number on the back label indicates who the tube manufacturer was, the picture quality of a set is determined by evaluating the picture itself and NOT by simply checking the suffix on the back label. The 27" tube option by Thomson-RCA in this model year - indicated by the "R" after the serial number - may lose focus at the edges.

Saving Picture Settings

Unlike sets which automatically save changes made to the picture settings, changes made to the picture settings in the user menu will not save unless one first enters "SET VIDEO STATUS" and then selects "SAVE AS CHOICE". This is also covered in page 31 of the owner's manual.

In order to store changes made to the the picture settings in the user menu:

1. First compare which color temperature you prefer by pressing the Video Status button on the remote, as this will be the starting point for your custom picture settings. Select 'Theater' if you would like a color temperature closer to reference 6500K, or 'Standard' to have a much more blue color temperature.
2. Press Menu, then CH- until you reach "SET VIDEO STATUS" and press Vol+
3. Make all your picture settings adjustments, and then select "SAVE AS CHOICE"
4. After that, you can select Choice as the Video Status to recall your settings.

Selecting 'Choice' will have the same picture settings for all inputs. If you would like to customize the picture settings per input, then the way to go about this is to set the Video Status to Standard, and then customize each source in the service menu, as detailed here.

Composite 240p Performance, Disabling Vertical Edge Enhancement

by Eli Krause

I. For composite decoding this set uses a Toshiba TC90A53N, a 3-line digital comb filter. One beneficial feature of this comb filter is its "1-line color dot interference reducer circuit". Depending on the console/revision, dot artifacting ranges from slight to moderate, and blending effects may be broken. Using an external notch filter to decode composite instead^[1] (such as is available in a RetroTink scaler) and sending that to the component input would blend all dithering patterns and remove nearly all dot artifacts.

II. Just as velocity scan modulation is intended to increase contrast at horizontal edges, vertical edge enhancement artifically boosts contrast at vertical edge transitions for composite and RF sources. To reduce this to its minimum, the high signal sent to pin 17 of the comb filter must be brought low which can be achieved by removing the resistor leading to that pin. On the AV-20D202 and AV-27D302 it is R239 on the bottom of the main board. On the AV-32D502 and AV-32D302 it is R247.
