Sony (AA-1) KV-32TW67 CRT RGB mod
EJ Massa found a big, beautiful Sony CRT on Facebook marketplace and decided to mod the fake wood grained behemoth with an RGB SCART input.
The Sony KV-32TW67 is a 32" console style CRT television from the early 1990s, built on the AA-1 chassis. Famous for its immersive picture quality, wood grain aesthetic, and deep built-in speaker system, it remains a highly sought-after model.
This set is RGB moddable.

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.

RGB mux diagram
Prepare the mux diagram. If you are building your own circuit, this diagram should help.
Performing the mod
Remove capacitors C315, C316, C317 on the M board and inject R, G, B to the positive terminals. Isolate blanking by removing R165 and inject blanking there.
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 calculator to play with your own values.
