So I've got a 13 inch cortex monitor that I've been trying to work on for the last couple months. No the monitor works and puts up a good picture, there is no green in the image, only red and blue.
I recapped it, tried swapping the green and blue gain pots and nothing was helping. Well today, I took the chassis off reflowed the solder at the header pins, swapped the blue and green gain pots back, and then made sure there was a solder bridge between the front leg of the green gain pot and the pad next to it. I also removed the header connector from the neck board to the chassis and then replaced it. Somehow, I was able to fix the monitor.
The colors were back. Then when I went to put the back door on, I slightly nudged the neck board And was back to this.
What could be causing this problem in the green circuit? The neck board transistor? Is there a resistor in the circuit that could be bad? I just don't get it.
