Last month three completely unrelated, yet equally mysterious, hardware problems kept me entertained at home. Each did have an obvious explanation in the end. Getting from symptoms to diagnosis, though, required both, guesswork and luck. Sure, I'm more of a software guy but I thought that I had a decent understanding of “how stuff works”. Well, looks like things have gotten pretty complex now.
Problem #1: our trusty PS3. Symptoms: We had just bought a new TV. Excited to see how games would look like on it, I powered up the PlayStation, and was greeting with a big blank screen of nothing. The TV was definitely set to display the correct input source, but, still, there was no picture. Swapping the HDMI cable to a different port on the TV, with the PS3 running, fixed the problem. It definitely left an uneasy feeling, though.
Things got even more confusing when I tried to play again another day and was again greeted with a blank screen. Now swapping back to the HDMI port that I had originally used gave me a picture. How could that be?
