Hi, Philip! Nice to see a good feedback. Shall try to reply one by one: 1) Fixed capacitors do have markings, but could get unreadable due to dust formation. I clean it gently using a spectacle cleaning cloth and IPA. If quite unreadable, I check its value and decide replacement depending on the usage there. 2) There are a lot of videos and guidance available in the web for converting CRT Tubes to oscilloscope. Please search. Here is one : https://www.youtube.com/watch?v=vHvbCWVtPzY

Your good stock of capacitors is proving to be quite useful. In the second repair you substituted quite a handful of electrolytic capacitors. Lack of even the closest required capacitor replacement that may be hard to come by will make a technician abandon a repair. You know the SMPS and some other sensitive circuits dont like modifications. The other thing is, I always wonder why you never mind to replace the ceramic capacitors, and how do you single out failed ceramic capacitors. Also how do you replace a ceramic capacitor knowing that some of them are never rated. May I request you that, one of this fine days explain how a modified crt tv can be used as an oscilloscope, I badly want one for use. New ones are costly, though very ideal. Also making use of a few crt tvs to make oscilloscopes will rescued some crt tvs on their way to the dumpsite in some places, and the environmental pollution degree caused by e-waste will have been lessened, even if marginally.

Yes, it is really challenging and therefore a thrill to work on such SMPS! Many thanks, dear Mark!

Which you no doubt have! LOL!
