Notes
The remote has quick access to the AV input, only requiring one button press to activate. However if you don't have the remote, this TV has a very annoying method for switching to the AV input. Every time you power cycle it, the default input is RF. To switch to AV, you have to press MENU twice, then the + button to switch from TV to AV input. Yes, 3 button presses just to use the composite input.
Despite having two speakers inside, they are both driven by the same mono audio signal. The TV is not true stereo.
The LA7674 jungle chip uses digital RGB which makes it incompatible with RGB modding. The datasheet lists "S-input for VHS compatibility", which assumedly means it could be modded for S-Video.
The neckboard is a nontraditional subtractive color format of R-Y G-Y B-Y with Y- passed as a fourth signal. The neck amplifiers will add the subtractive color signals to the Y- signal to convert it back to RGB during amplification.
