Look for capacitors near the pins 14, 15 and 16 of the Ratasheet visual inspection and multimeter. Based on previous comments and the similar pinout, this chips likely behaves very similarly to other CXA21xx jungle ICs https: Any case CXAS looks to be the same pinout for what we need. It leaves me confused as to why there is an issue.
Tue Sep 19, 5: They should stay at 75ohm Cxs2139s series will control color. I just checked and my chassis has the same connector. So pins 14,15,16 I’m snipping at the legs of the capacitors coming into the osd and I’m hooking my rgb wires from my game console their to the osd input of pin 14,15,16 then I’m I’m feeding power to the rgb vcc on pin 18 I should add somewhere around 1 volt up to 9 volts to get it to blank to rgb the circuit says it takes 9 volts on their what should I do about the black pin The hardest part was finding some volts to stick in the blanking pin; it took me an hour to realize 9 would be fine.
I was hoping some of you had some suggestions on what to try next. Anyway I have tried to draw a simple diagram of what I have done, I am assuming it is wrong: When in parallel it was close enough to 75 that it shouldn’t of been a problem for the console but the OSD takes a huge hit from its Vpp being grounded so heavily.
I figured that with the way the boards slot together, the fewer wires I could have dangling between the better. Remember to terminate your RGB lines console side with 75ohm resistors, I usually do it on the scart connector Many of the rear inputs are make or break connections, the TV will only allow sync or audio to pass through if there dataseet plugs in the sockets.
You can bypass this by using the luma channel on svideo for sync and bridging the svideo grounds, wire your audio to that AV channels inputs and cut the trace that connects left audio white to right red.
Thu Sep 21, 2: Awesome,that will work just fine. Wed Sep 20, I should probably add some installation datashert to that gallery. Daatasheet Sep 20, 5: I know about the 75 termination,just wanted something to mess around with,can dial it back to normal easy.
Cheering you got it working.

Are these pins used for anything? It is currently Mon Dec 31, 1: Black levels and everything else are fine, nice little set.
The OSD may be constantly feeding the lines tho which could be the cause of the ghosting.
I prefer to use the stock traces and shielded cable where I can to avoid interference. I think datashee left the original terminations connected or your caps are too small dude, make sure they have the number on them. Mark OZ was connecting 75 ohm termination resistors and the chassis already had ohm termination resistors.
Thu Sep 21, To ground with a and use 1 uf caps and make sure it doesn’t have any resistors on that lineI’m trying to fiquire where to take the rgb signal away fromand send it to what chip the jungle chip then bypass the micro controllerI hope I’m on the right track. But the console is still to washed out and bright in this configuration also. You’ll have a hard time finding them cheaper anywhere else. The pins I had laying around from a Pi zero datssheet it made the install much easier for me.
So for a nominal 75R termination anything between 60R and 90R should actually work fine.

I’ll try feeding the sync directly to the jungle IC. Well that is both some coincidence and very sucky. See if it changes the screen.
