Repairing a Neewer 660 Studio light - How Hard Can It Be? -- Episode 594

I’ve got a studio light which has suddenly become faulty, how hard could it be to fix it rather than replace? In today’s episode I try and fault find the PCB to see if its a fault I can fix.

  • It is brave to video skills and techniques because everyone can comment on how to do it better. Don't let it stop you though. Hopefully everyone learns. One good test in a situation like this is a smell test - burn components usually smell burnt. It can narrow down the possibilities before a lot of disassembly. I doubt the fumes are healthy though.

    Smell tests, yes thats usually an obvious one, along with heat. Years ago I was fault finding regularly for work (thankfully with circuit diagrams and parts lists), and a very infrequently we'd get really stuck, and the last resort was to just power it up without a current limit and see if anywhere went pop, got hot, started to smoke etc
