More PARcan repairs. If anyone par can, I can.

Описание: Another (long overdue) video covering even more LED PARcan repairs; apparently if anyone (PAR)can, (I)can...

See if you can spot a recurring theme with the failures. Also see if you can spot the point I gave up and clicked export.

I was going to include the installation of another new LED PCB along with more tests, but the video was long enough as it is. Work, my mental health and inability to say "NO" has already delayed this video (check the date on the PAT Test stickers) so I can either procrastinate further or say "F*** It, That'll Do".

I'm confused because the thermistor on the new PCB behaved exactly like the one on the old PCB - the resistance crept up as it cooled down, in other words a Negative Temperature Coefficient or NTC. Perhaps it was just the wrong range of values for the PARcan control PCB to understand? I was going to conduct further tests on the new NTC thermistor, but another repair came onto the bench which was swept in preparation, the piddly component went in the bin and that as they say, was that.

The music in the background with my voice should give an idea of what it's actually like at my workbench, albeit without the swearing and copyright strikes.
