Update, in my desperation I've consulted ChatGPT and it told me that this missing inverter would actually be used to power the backlight of the LCD. Sure enough, the pins of the connector on the faceplate go straight to what seems to be the LCD backlight (pic related). AI has determined the type of backlight to be EL. All this actually seems to be correct, but how do I choose what EL inverter to buy and how do I not cook the backlight? I don't know what voltage and frequency it requires :(
