Notes

(NOTE: My particular set has an worn chassis and tube. It is not reflective of the full quality a healthier example would provide.)

In my own personal opinion, picture processing quality from the Sony jungle chip is a mixed bag. Firstly, there is red push, and there is no service menu setting to turn off the oversaturation. The only workaround is to turn down the color saturation in the standard menu and perform a white balance. Secondly, there are luma transition errors in the signal. Turning down sharpness can reduce the artifacting, but it will not be fully eliminated. Lastly, there is some chroma bleeding, but this may be due to high hours on the tube.

The original remote is required to enter the standard menu. Contrast can only be adjusted via the PICTURE buttons on the remote.

TRINITONE toggles between color temperatures: LOW for 6500K, and HIGH for 9300K.

This set has nasty Velocity Scanning Modulation (VSM) that cannot be turned off in the standard menu. The only way to disable it is to pull the jumper that injects it from neckboard. (The provided pictures are of the set with VM disabled.)

A notch filter can be engaged in the standard menu to clean up composite video.

Sound

Set can be paired with detachable speakers that can be placed on the sides or further back. Furthermore, a subwoofer is placed on the top back area of the set, providing nice bass.

RGB Modification

As for RGB modification, the process is rather complicated. Basically, it entails hacking the i2c bus to enable the analog RGB pins on the jungle IC.
