/vr/ - Retro Games

Alright, here's the deal

I found this LG 21FX5RG (pic is not actually my tv) tv for free and I want to RGB mod it by overriding the OSD.

I have the manual here:

http://www.archivotecnicosaurios.com/descargas/tv/seccion_ordenada/12950_Chassis_MC-059A_Manual_de_servicio.pdf (schematic is on page 23)

This is my first time doing something like this, and I'm not affraid of wrecking the tv, and I also know about the dangers of tinkering with CRT's.

But first, I need to know how to achieve this.

So far I know that pins 12, 13 and 14 from the LA76931 are Red (1.6V), Green (1.8V) and Blue (3.4V), info taken from http://selvanmani.blogspot.com/2017/11/la76931-data-voltage-tn-government-free.html

I have yet to find the blanking pin though.

Can anyone give me a hand and let me know where should I tap things and the value of the resistors I should use? I would be eternally grateful.
