Just a quick thought on this one Cheering you got it working. Google [Bot]justice99 and 7 guests. 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.

The legs of these caps furthest away from the chip are should be an appropriate “snipping point” where you can disconnect the OSD RGB by desoldering and later inject your own RGB. I know I’ve been mistaken about the need for diodes before but this seems like maybe a good spot. I did datashete for dwtasheet 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.

There is a noticeable difference in the picture.

Tue Sep 19, 5: Hi Guys, I pondered creating a new thread for this but thought it’d make more sense to post here. Well that is both some coincidence and very sucky.

Thu Sep 21, 1: I figured that with the way the boards slot together, the fewer wires I could have dangling between the better.

I thought maybe it had an odd blanking system but no. Previous topic Next topic. When in parallel it was close enough to 75 that it shouldn’t of been a dstasheet for the console but the OSD takes a huge hit from its Vpp being grounded so heavily. Awesome,that will work just fine. For now I removed my 75 ohm cxxa2139s 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.

What technique did you use to do the mod? 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 datasjeet 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. 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.

When I read your post I did a history search dahasheet the Jungle IC and it came up red, So I looked at the service manual and found a set I have that looked similar. I was hoping some of you had some suggestions on what to try next. Thu Sep 21, 5: It is currently Mon Dec 31, 1: So the set will not allow signal via those inputs until a plug is actually in the socket.

So we have been connecting the console and OSD directly together, which causes all types of issues. To control color you can add pots to each color channel.

They should stay at 75ohm In series will control color. I’m pretty annoyed as it means I now have to reopen units and switch them to an OSD hack.

The diode should mean the OSD remains at it’s initial whatever. Well the parts came in and Fxa2139s done did the thing.

Thu Sep 21, 4: Pin 5 of IC is the 5V output.
