I've had my original apple iie and Monitor II since I was a teenager. Its been working great all these years until the other day a friend asked about it and I booted it up. The computer sounded fine but the monitor display was having issues. I finally got it to display after tweaking the knobs and then shut it down. Now I tried to use it again and the power light is on the monitor but I do not see any video being displayed. I tried adjusting brightness and contrast but do not see any image. I thought it might be the video port or the cable, but I tried changing the cable and connected it to a old iic I have that is known to be working and same result, no display whatsoever.
Any ideas on anything I can try to fix it or at this point should I just congratulate it on its long life and move on and try to find a replacement?
