You know I appreciate the quality of this video so much. The learning going on for me is so great that I can absorb and use this as a learning tool to help me be a better trouble shooter on my own equipment and the correct procedure for finding faults especially in complex equipment. My laptop will not fire up and with this technique I can find the components I need to replace my unit to make it functional again so as to use my computer successfully and not have to spend money for a tech to do the work for me. 2 years ago I plugged in the power supply backwards so I am pretty sure the failure will be right after the power supply.
A joy to watch you work through cause & effect and the a solution. A humbling example of a repair with multiple issues. Well documented, filmed and presented. A+ for your post production skills. I wish content like yours was available while I was growing up instead of cartoons. I might have made myself into something :) Cheers!
Thanks for the great video! It was great watching you work through the faults, very enlightening and educational. I would like to have seen more of your switch repair portions!
Very well done demonstration.. I have a similar device, the CRT trace becomes weak and disappears after about 10 minutes of being turned on, any ideas ? Thanks in advance, ED
Hello! Thanks for the great video! I have similar oscilloscope with the problem in channel B. I wanted to see the signal on the transistors, which you have shown. But somehow, my digital oscilloscope does not want to see the signal even on the channel A, which works fine. Do you have any ideas, what can I do wrong? I am using cheap tester as a source of the signal. The signal from it, I can see with both oscilloscopes, but not on those transistors. Could you, please help me?
Hello, there. Thanks for the video. I have a PM-3217 that i am rebuilding. but I don't have the detailed schematics you have. How did you com by there schematics?
I recall that it was fairly easy to find them online, though I can't remember where now. If you can't find them, send me a message via the form at zx.zigg.net and I can send you a copy.

Thankyou, managed to fix my pm 3216 with your video. Had the same trigger fault, same channel.

Great systematic trouble shooting and diagnostic techniques. Very impressive

use a pin or piece of paperclip in the jaws of your alligator clips to help ya with them hard to reach places. Great vids.

Great video, whole heck a lot of Transistors there. :)
Modern oscilloscopes have many, many more; they are just much, much smaller.
Part 3 should be along fairly soon.
Very nice video!
Small fluffy animals all the way. Gotta have a universe to be evil in.
