Thanks for the help. I will be attempting this soon. Will post results afterwards.Bad Company wrote:vincediesil wrote:Long time lurker here, and I've trash picked an Admiral TV with a Sharp CRT.
I'm hoping that it can be RGB modded, I've found the chip is a X2933CE. I've found the schematics for it here :

If I understand this correctly, I want pins 15, 16, 17 for R G B, AND pin 14 for the blanking.
After that I'm kinda lost. Each line should have a resistor to ground, and pin 13 appears to be that.
I Appreciate any help you can provide.
Thanks!

Yes Pins 14-17 are correct.
Try this for your inputs:
Notes:
-The colored circles are your new RGB inputs.
-The 75Ω resistors are in series with the original resistors, which no longer go directly to ground.
The external video jack (yellow RCA) is your sync. (it's connected to pin 37)
