Thu Sep 21, 2: I think you’ve left the original terminations connected or your caps are too small datashfet, make sure they have the number on them. Tue Sep 19, 5: Previous topic Next topic. So for a nominal 75R termination anything between 60R and 90R should actually work fine. 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.
TV RGB mod thread. Tue Sep 19, 1: Awesome,that will work just fine. Can see it on page Cda2139s I read your post I did a history search for the Jungle IC and it came up red, So I looked at the service manual and found a set I have that looked similar.
You’ll only need 1k pots really it wont need much adjustment. You can bypass this by using the luma channel on svideo for sync and bridging the svideo grounds, wire your audio datashedt that AV channels inputs and cut the trace that connects left audio white to right red. Cheering you got it working. I wasn’t aware of that. Wed Sep 20, 1: An OSD hack produced a nice clear picture. Yeah I was totally wrong, you get There is a noticeable difference in the picture.
I was instantly impressed with the sound as cube TVs usually have poor audio.
You don’t need a switch for this set, just 75ohm terminations, n caps and 5v to blanking. Oh so should I take the rgb inputs off the micro prossesor and wire it straight to the rgb inputs to the and I should add see voltage to the blanking osd input what voltage should I start with and also I should terminate the rgb signals off the micro controller and should I isolate the blanking signal from the micro controller and use a switch to go from me controlling the osd when I set up rgb so I should isolate the micro controller from changing the rgb signals with a 6 way switchI need to add 75 oh resistors.

Hi Guys, I pondered creating a new thread for this but thought it’d make more sense to cxa2139d here. For now I removed my 75 ohm resisters and replaced them with have ohm variable resistors on the rgb lines and that fixed my brightness issue,picture is better but adjusting the color would be the next best thing.
Mark OZ was connecting 75 ohm termination resistors and the chassis already had ohm termination resistors. Mon Dec 31, 1: Page 35 of You live you learn So the set will not allow signal via those inputs until a plug is actually in the socket. Following your progress has made me understand why the mod of the BG-1S chassis was so much more successful. Tue Sep 19, 7: I cant remember if before the clamping caps or after is best. I did this for the first time last night because a Panasonic set would not take sync via svideo or component, and I found that the sync wire needed to be shielded as it was picking up a lot of interference.
What technique did you use to do the mod? The pins I had laying around from a Pi zero and it made the install much easier for me. 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 are plugs in the sockets.
Any help with this would be greatly appreciated.
Below is a summary of how I wired things and the troubleshooting steps taken https: Black levels and everything else vxa2139s fine, nice little set.
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 Pin 5 of IC is the 5V output. Lifting the pins is fine really, and your install picture looks fine also.
This set and Jungle reminded me of a set, I swear I had done one before Initially I used a switch to wire all 4 jungle IC pins back to the board, but removed it later as a troubleshooting step. Even if you switch the original resistors on the OSD lines out for 75ohm the console is still too bright and black levels are all screwy, like the OSD is amping the console rgb feed.
I should probably add some installation pictures to that gallery.

I’m pretty annoyed as it means I now have to reopen units cxa2139z switch them to an OSD hack. For trouble shooting put a switch on the 5v blanking with no console connected. Wed Sep 20, 4:
