Exactly, remove the 75 ohm in and have like 1.5 k to voltage on the input or say 5k pots to test. Then have them tied to ground on the output. Also may need some decoupling caps after the pull up resistors. So it would be R--- 0.1uf--5.3mresistor--i.c.--(maybe 220uf cap)--75ohm--Pr.
Thanks for the advice Eddiesamma. Before your post here I had tried removing the 75 ohm resistors tied to ground on the input, and replaced them with 3.3k resistors tied to vcc, and I already got an improved component output without changing anything else on my board, which actually follow ACE's 5.0 schematics through to output.
My boards and ACE's schematic images are posted in my first post if you want to take a look.
So right now my boards with switching the current RGB traces with the one resistor to voltage modification to each goes more like this order ...
RGB in --- 3.3k resistor --- 1uf cap --- BA7230LS IC --- 2SC945 transistor --- 75 ohm resistor --- 220uf cap ---
then Y has an added 62 ohm resistor just before final output
Pr has an added 20 ohm resistor just before final output
Pb goes directly from the above last 220uf cap to output
I'm a little confused with your "R--- 0.1uf--5.3mresistor--i.c.--(maybe 220uf cap)--75ohm--Pr" trace.
It's a little more different than what ACE's schematics follow.
Would you replace the 1uf caps the current design shows to use before the IC, with .1uf caps you show to try?
What is the 5.3m resistor before the IC you you list, is that an added 5.3 million ohm resistor you want after the .1uf cap, but before the IC input for each color?
You don't show transistors at all in your trace, aren't they needed, or did you just forget to add them?
Also, in ACE's design, the pull down 75 ohm resistors are placed before running the output signals through the final 220uf caps, but you seem to show the pull down resistors placed after the 220uf caps.
And last, do you think I should skip the final 62 ohm and 20 ohm resistors in that the current design has in the final output for the Y and Pr channels?
Thanks for your help!
