My daily carry just stopped working only me. Started last week with the voltage flickering. Found one lead was broken and I ordered new ones. New leads didn't change anything, it displays “-1” on all settings but on continuity will give the tone when touching. Checked battery and found the fuse blown. Replaced fuse but same results. Cleaned the dial and led display and its parts. Board looks nice and clean no burned or broken components. Nothing traumatic happened to this multimeter I put it aside when I found the lead broken and didn't touch it until I got the neAnyone have any ideas what's going on with this Craftsman 82345 multimeter?

give the switch contacts a real good cleaning to rule out the easy thing -
Cleaned everything with alcohol and eraser, everything looks clean and new…Comment

check all the surface-mount resistors - the pictures arent good enough for me to see them.

i dont see a 10 amp fuse .is there any chance you measured volts when set on amps ?Comment

My two Aneng multimeters were not working recently. One of them was only 2-month new.
I know the feeling.
Since you said the fuse was blown and replaced, are there any other components got burned too? e.g. U3, U4, Q2, and the components around there, etc.

When I assembled dreamcast I mistakenly fastened long bolt and It resulted in
cutting tiny trace.
This tiny trace(Total width of white coating is 5.5mm) is between R337,R343 and IC101 and it is covered with white coating in the below screenshot.
Firstly I tried to bridging tiny broken trace with my own eyes...But it is totally impossible..So a week ago, I ordered G1200 Digital Microscope and I magnified this tiny broken trace with it.
But It seems that It is really very tiny trace So I plan to order 0.1mm coper wire from aliexpress in order to bridging... -
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?...

I've had this ONN ONC18TV001 for about 5 years. My wife left it on 24/7 as a night light so not too surprised it broke where the screen was still displaying the picture just there was no Backlight. The power/mainboard had voltage for the back lights but when you turn it on it starts high over 100v then within less then a second would go down to 30 something volts if I remeber correct. I figured I should check for a bad LED since that's certainly a common failure on these. I did find one LED that I doesn't light up using the diode setting on my multimeter. There is one other thread about this TV... -
Hello guys! I need a little help, I have one laptop for repair, it is an Aorus 17G YD, gaming laptop. Broken display, some cable ripped form daughter board connector, case broken, battery discharged and probably locked, etc. After I did the most tedious job I ever did on soldering back the broken cables (shielded cable) , I measured resistance on CPU and GPU core, 3 and 5 v ps and any coils I find on the board, everything seems to be fine. After I plugged the charger I don't get the power led light on from the charger connection maybe because the battery is locked , but on power button I have... -
Hello, I have a Fujifilm hybrid camera with an issue : the time don't run. I set 12:00 and 3 min later, the same : 12:00
I saw an obvious root cause : a broken quartz (resonator). But with the box broken, I can't read the marking code. Probably : 464… or A64…
I found on the web a picture of the same camera board but with marking code very different. Probably : A7…5N
I'm searching another one for compare…
Do you have an idea or another way for find the frequency of this resonator please ?
(I did not found the manufacturer of this component ? And I did not found the...
