Here is a little more information from my previous post.
Philips TP3284 C101 / 32G7 Chassis. A bit new to this so bear with me. Found unpopulated spot on board where RGB input goes in to jungle chip.
Found the service manual here: https://www.manualslib.com/products/Phi ... 10760.html
Page 82 Service manual "RGB Processing".
Here is a snippet of what I have done so far.

I believe the BL requires 3 volts input. Not sure about anything else.
Can someone help me figure out what resistors/capacitors to place in-line on here? Should I put the 47nf caps back on here? How do I do OSD mix? Or should I do a switch??? Any suggestions would be appreciated. Thank you for any help.
I think you want to do an OSD mux targeting resistors 3065, 3066, 3067 RGB
Don't bother with the resistor calculator, just use two 75R twisted in each (75 + 75 = 150)
For blanking use the 8 bit guy method from his second video on resistor 3068 for blanking.
Thank you again for the help.
So from what I understand then - I need to put back the 47pf resistors that I took off - then remove 3065,3066,3067, and 3068 resistors and you want me to use 2 75ohm resistors in series to make 150 ohm on each. Then just throw a switch in there for the blanking line ( like from here: https://youtu.be/NkpSBK3g-gA ) and inject RGB on M20.
