I have finally decided to release this video next week (May 8.) I've been sitting on this for quite a while as I finished this video in mid March so I don't even mention Patreon or the second channel. 

For this video, a viewer donated an old Apple //c monitor that isn't working. Can I fix it? Watch and find out. :-)

One of my IIc monitors died seconds after turning it on a couple years ago - I haven’t looked at it yet since I had another, but I hope it isn’t the same model as yours! What a nightmare to work on!! Sorry you couldn’t get it fixed!

I have a few of these //c monitors some working, some not. The last time I tried one of them it worked for about 2 minutes, then the Rifa capacitor self destructed and the monitor went dead. As Adrian did, I also opened mine up and thought, where do I start to disassemble this thing ?. Thanks Adrian for the heads up on how to disassemble it, without going completely insane !
