My DVI output is all red!
My macbook is approx 2.5 years old now and I have had no issues what so ever with it, except one day, I plugged my 2nd display into my DVI out and even though the screens were shared correctly, my 2nd display was pretty much totally coloured in red! i have tried plugging into LCD TVs over DVI-HDMI but the same happens. Perhaps a pin is damaged in the DVI connection port causing blue or green to stop coming through?, or could it be something more serious? Any ideas on what I can try? Is is possible to replace the DVI port rather than replacing the entire motherboard? Thanks in advance!
Это хороший вопрос?
I had the same problem. I checked the port with something similar a plastic fishing line and now it doesn't work anymore. I guess the contacts are not working inside the port.
If there is no a way to change the port, how could I check the conductor inside them?
