I think the OSD is less. On my rgb modded sony trinitron kvfs the color control and hue on the osd is disabled when I use rgb but the other controls work just fine like brightness and picture,you guys think it’s hardware or software as would like to re-enable them. Not crossing my fingers though. I have a bit of a soft spot for cube tvs, and even though this is flat screen I grabbed it to see what it could do.

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. An OSD hack produced a nice clear picture.

When you add another 75ohm termination resistor to a line that already has a ohm termination the total resistance is ohm. TV RGB mod thread.

When 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.


Initially I used a switch to wire all 4 jungle IC pins back to the board, but removed it later as a troubleshooting step. Wed Sep 20, 1: Oh so should I take the rgb inputs off the micro datasyeet 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.

Below is a summary of how I wired things and the troubleshooting steps taken https: I think you’ve left dagasheet original terminations connected or your caps are too small dude, make sure they have the number on them. I’m pretty annoyed as it means I now have to reopen units and switch them to an OSD hack.

Thu Sep 21, 2: Following your cax2139s has made me understand why the mod of the BG-1S chassis was so much more successful. Tue Sep 19, 5: Remove the leg of each n capacitor OSD side of the pins, keep the leg that goes directly to the jungle in place these lifted legs are your main RGB in, centre switchand wire your OSD lines to the holes. I just checked and my chassis has the same connector.

Wed Sep 20, Hi Guys, I pondered creating a new thread for this but thought it’d make more sense to post here. Can see it on page I cant remember if before the clamping caps or after is best. So I tried a proper OSD hack on these units and yep, black is darasheet black as midnight. But the console is still to washed out and bright in this configuration also. They should stay at 75ohm In series will control color.

Page 35 of You live you learn As you can see my caps are 0. Previous topic Next topic. Thu Sep 21, Were it not for the convergence issues this could very well have been a religious experience. 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.

But at the same time the picture is superb and no menu settings need to be changed between consoles. Wed Sep 20, 4: I was instantly impressed with the sound as cube TVs usually have poor audio.

Mon Dec 31, 1: Well that is both some coincidence and very sucky. This chip has a very brief datasheet! It leaves me datawheet as to why there is an issue.
