Repairing my CMVS and I've run into an annoying bug. It's not a big deal, but I'd like to fix it if possible.
My Video out consists of:
• RGB through a AES style Din-8
• Component & S-video from a Neobitz encoder.
RGB signals to the Din-8 go through a little trimmer pot and a 220uf cap as recommended by some members here, it looks excellent on my PVM and should work great on an OSSC when I get one.
RGB lines have a separate set of trimmer pots added before they go into the NeoBitz encoder as I wanted to be able to adjust the component signal since straight from the Neobitz was a bit bright for my TV.
To make this more clear, raw RGB lines from the motherboard are split, each going through a set of pots, one for RGB out, another for the Neobitz. It works well and I can adjust them independently.
Problem I've noticed is when using RGB, the video gets much brighter when I unplug the Neobitz encoder. There is one plug going into the encoder that carries RGB+S 5v and G, and when I yank that plug out and don't send anything to the Neobitz the RGB feed gets much brighter.
Is there a way I can somehow isolate the signals so the Neobitz isn't essentially sucking some signal strength when I'm not actually using it. I know I could add switches to the lines, but that's really annoying and I don't have any place to install them that doesn't require opening the CMVS to change them. I could probably ad a switch to just the 5V line going to the Neobitz, but I'm not actually sure if that would help, as I think it's more that the RGB lines are always connected, and I really don't want 3 different switches I have to flip just to use component vs RGB.
I'm not too great with electronics, is there some better and more passive way I can do this?
In the end it doesn't really matter that much, I'm already turning the RGB lines down a bit to go into my PVM or future OSSC anyways so the reduction in signal strength might not matter, but it bothers me and seems like there should be a better solution.
