Sony (AA-2) KV-32V35 CRT RGB mod

The Sony KV-32V35 is a 32" curved CRT television released in the late 1990s as part of Sony’s respected Trinitron line. It features an aperture grille picture tube that delivers bright, vibrant colors. The television includes RF, Composite, and S-Video ports, but it lacks Component/YPbPr and RGB inputs. For audio, it has built-in stereo speakers with SRS (Sound Retrieval System) and WOW True Surround audio processing.

CRT safety

Caution

You can die doing this! So read carefully! CRT TV is not a toy. Do not open a CRT TV. If you don't have any prior knowledge about handling high voltage devices, this guide is not for you. CRT TV contains high enough voltage (20,000+ V) and current to be deadly, even when it is turned off.

Performing the mod

This mod uses the RGB mux board. This is optional, but will make your mod easier and stable. You can also create the circuit presented in the schematics above without the board. Please also checkout the mux calculatoropen in new window to play with your own values.

This is the daughterboard for the rear connectors. It provides a convenient place to mount the panel-mount RCA jacks for YPbPr. I 3D printed some plastic washers. (Ultimately I removed the resistor between Y and ground due to some brightness issues)

Front of the neckboard. Again, the wires were for a G1 mod that I did not end up using. I ended up removing the wires and tying these pins back to ground like they originally were.
