Is it possible to test small ceramic disc capacitor with analogue meter?

by chth96

I read EBOOK of Testing Electronic Component and found that

"In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."

Is it really possible to test small ceramic disc capacitor with analogue...

Help with trying to fix phone that is not charging (Pics inside)

by SluggerB

I have two TCL A30 phones.

Old Phone: This phone worked fine for years, then stopped charging If you plugged a charger into it, the phone would make the charging sound, the phone would tell you it is charging, but the battery icon would not have the charging symbol in it and the battery would not charge.I tried new battery, same behavior.

New Phone: Works fine, bought as a donor board to try and repair Old Phone

My interest here is to repair Old Phone, using components parts off New Phone if needed. I am not interested in replacing Old Phone with New Phone....

Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!

I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:
