Would i be testing them in ohms

Re: Can i test MLCC caps with multimeter?
yes, and capacitance.
but mostly just looking to see if they are shorted. -
Re: Can i test MLCC caps with multimeter?
Ty stj.. i have tested some that start at -13 ohms then start climbing to 500 900 ohms that normalComment

swap meter leads over and try againComment

Re: Can i test MLCC caps with multimeter?
The cap may also be connected in parallel with caps, true test for capacitance will be testing off the board.Never stop learning

Re: Can i test MLCC caps with multimeter?
Hi everyone been testing the caps on the board between lcd and tcon board at 200k all measure around 200k almost but 2 of them that are close to the ribbon cable near tcon only measuring 2.2k the small one i circled on the right and the one circled on the left. Weird thing is that when i disconnect the ribbons coming from the tcon there values start going up to 200k like the others. What can be the problem?Attached FilesComment

Re: Can i test MLCC caps with multimeter?
All that means is there are other components on the t-con that are in parallel with those caps. this is common.
You ask: "What can be the problem?" maybe tell US what the unit is and the problem you are trying to repair.Comment

OP never tell us the make or model of the unit working on, no pictures of the screenshot, and instead of doing the follow-up OP makes this new thread instead.Never stop learning

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:

I am new to electronics and I'm understanding most of what I'm reading but I have a mosfet on my board that I've identified as a P-channel Trench Mosfet. I haven't a clue how to test this and what I should expect to see with the multimeter probes. I am hoping someone with years more experience than myself can help me understand how to use a multimeter to read this. Please look at the drawing I have attached to this and can you try to explain to me what I should be doing with my multimeter in diode mode and what results I should expect from a good mosfet?...

Hi Folks
Need some advice on how to test a subwoofer amplifier if i have access to only a multimeter.
Problem
I have a Boston Acoustics active Subwoofer (soundware S). Its rated output is 200W. But the output i am getting is very low i can barely hear/feel it even if put the gain at max. I replaced all the capacitors in the Subwoofer amplifier but still no change.
Is there anyway to test this without getting an oscilloscope/Function generator to see if the fault is with amplifier, driver or the source??
Any advice would be appreciated... -
Greetings everyone,
I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...
The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.
Upon closer inspection... -
Hello:
I have both these laptops that appeared to have the same fault so I thought I would have a go at replacing the PCH as something to learn, they both are using the same PCH.
I started on the ACER:
Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.
I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap...
