After a long search I found out that my 14'' Toshiba CRT uses the chassis U6B (attached) and I noticed it has a RGB IN, meaning that supposedely this TV could be RGB modded, I'm not sure it could, because it has no Composite video IN (this model only comes with RF).

In order to RGB mod a TV you need a jungle/micronas chip that has a blanking line, RGB IN (analog) and the TV should have composite video IN for the Sync (mixed Horizontal and Vertical sync).

What I have in this TV is shown in the pictures. Could the Y-OSD be the sync? Does H. BLK and V. BLK stand for Horizontal and Vertical sync?

Pictures from the microcontroller:

Picture from another component that I couldn't find the model or the name, but it's probably the the OSD.



Also, can anyone provide the service manual of the Toshiba TV 1482 EAV? I can't find it anywhere, I'm only being able to find that very same scanned schematic that I'm already attaching here.

Or is it the same ?

Yeeep. It's the same.

Still the same schematic.

 

What are you wanting to achieve?

 

What are you wanting to achieve?

Need to inject 15khz RGB signal into a TV's chip, for playing retrogames (for example, with Raspberry Pi), I've already attached the schematics here, I believe it might be possible. I've successfully done that before, but with a more modern CRT. This one now only have a RF In, no composite video at all, but maybe in the schematic there's an unused AV/S-video In, I'm still checking.
