Akigor Yeah I was totally wrong, you get You live you learn See if it changes the screen. Page 35 of Black levels and everything else are fine, nice little set. TV RGB mod thread. Then something like an 90ohm resistor termination on external RGB lines?
Below is a summary of how I wired things and the troubleshooting steps taken https: Did you wire directly to y on the Jungle? But the console is still to washed out and bright in this configuration also. It leaves me confused as to why there is an issue.
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. Any case CXAS looks to be the same pinout for what we need. Following your progress has datsaheet me understand why the mod of the BG-1S chassis was so much more successful. There is a noticeable difference in the picture. As you can see my caps are 0.
Are these pins used for anything? I was instantly impressed with the sound as datadheet TVs usually have poor audio. 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. Well the parts came in and I done did the thing. Based on previous comments and the similar pinout, this chips likely behaves very similarly to other CXA21xx jungle ICs https: Mark OZ was connecting 75 ohm termination resistors and the chassis already had ohm termination resistors.
Wed Sep 20, Tue Sep 19, But at the same time the picture is superb and no menu settings need to be changed between consoles. Tue Sep 19, 2: Thanks for the response man! So we datahseet been connecting the console and OSD directly together, which darasheet all types of issues. Anyway I have tried to draw a simple diagram of what I have done, I am assuming it is wrong: Wed Sep 20, 1: 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.
They should stay at 75ohm In series will control color. I was hoping some of you had some suggestions on what to try next. I just checked and my chassis has the same connector. Tue Sep 19, 1: Dagasheet for capacitors near the pins 14, 15 and 16 of the IC visual inspection and multimeter. I know about the 75 termination,just wanted something to mess around with,can dial it back to normal easy.
The hardest part was finding some volts to stick in the blanking pin; it took me an hour to realize 9 would be fine.

Goshura shmups. I think the OSD is less. Thu Sep 21, 1: Well the parts came in and I done did the thing. Tue Sep 19, 5: Users browsing this forum: 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 caxs. Cheering you got it working. See if it changes the screen.
