Yeah, I’ve done my share of tinkering over the years. Had to unjam one of my Laserdisc players more than once. There isn’t much left in consumer electronics one can tinker with the insides today. I’m amazed I was able to fix the now ten year old HDTV in my living room. I came very close to junking it, but a little online research really paid off. It just needed some bad capacitors replaced on the power board. I had some help with the de-soldering and soldering, but I did the rest. It’s as good as new.
I doubt the super slim flat panels made now even have that many circuit boards within.
