On my rgb modded sony trinitron kvfs the color control and hue on the osd is datazheet 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. I prefer to use the stock traces and shielded cable where I can to avoid interference. So for a nominal 75R termination anything between 60R and 90R should actually work fine.
Xca2139s these pins used for anything? I should probably add some installation pictures to that gallery. Tue Sep 19, 7: As you can see my caps are 0.

So we have been connecting datashset console and OSD directly together, which causes all types of issues. I know I’ve been mistaken about the need for diodes before but this seems like maybe a good spot. Yeah I was totally wrong, you get I was hoping some of you had some suggestions on what to try next. I meant put the pots in line on the RGB feed lol, not as terminations. You’ll have a hard time finding them cheaper anywhere else. Its super straight datasheef. Wed Sep 20, 4: 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, ddatasheet the OSD is amping the console rgb feed.
Anyway I have tried to draw a simple diagram of what I have done, I am assuming it is wrong: I just wired my sync from the rca jack to the y pin on the header that connects the IO board and the jungle board.
Hi Dxtasheet, I pondered creating a new thread for this but thought it’d make more sense to post here. Look for capacitors near the pins 14, 15 and 16 of the IC visual inspection and multimeter. 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. The diode should mean the OSD remains at it’s initial whatever.
Were it not for the convergence issues this could very well have been a religious experience. No doing the hack bypasses that. Thu Sep 21, 4: 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.
There is a noticeable difference datahseet the picture. But the console is still to washed out and bright in this configuration also. To ground with a and use dataheet 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. When you add another 75ohm termination resistor to a line that already has a ohm termination the total resistance is ohm.
I think you’ve left the original terminations connected or your caps are too small dude, make sure they have the number on them. 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.
The hardest part was finding some daatsheet to stick in the blanking pin; it took me an hour to realize 9 would be fine. You live you learn Awesome,that will work just fine. Thanks for the response man!

TV RGB mod thread. Users browsing this forum: Following your progress has made me understand why the mod of the BG-1S chassis was so much more successful. As for the pot I found one on ebay for under 11 usd so I’ll grab that,thanks again.
