Samsung WD80N645OOW died mid-cycle

by mrsith

Hi fellow lifesavers.

I have a Samsung washer-dryer WD80N645OOW which died mid-cycle. No response to anything, completely dead.

Checked the socket, the plug fuse, all good. Took it out to examine the boards.

There is a relay clicking on the mainboard. Upon applying power, I can see a diode flashing on inverter board, after a while a diode on main board lits up for a split second, then I can hear a relay clicking. This repeats a few times, then everything dies completely.

I've been trying to examine the main board, but it's a bit difficult becuse...

HP ELITEBOOK 1040 G6 - SCHEMATIC

by gregor13

Hi everyone,

I'm reaching out for some help with a problem I've encountered with my HP Elitebook x360 1040 G6.

I recently noticed that my computer wasn't powering on. After a bit of investigation, I discovered a burnt component on the motherboard. Unfortunately, I'm not entirely sure what this component is, and I would greatly appreciate any assistance in identifying it and determining if it can be replaced. Model of the HP motherboard: brighton-6050A3037501-MB-A01(A1) (l63007-601)[ATTACH=JSON]{"alt":"Click image for larger version Name:\t3.jpg Views:\t17...

Apple Macbook Air M1 A2337 Trackpad problem

by Skrndelj

Hello all,

I am repairing a Macbook A2337 and i have a problem
The Macbook is stuck in restore as someone before me tried a DFU restore and bricked the device, now i can't do a restore as AC2 throws error 1 which is related to the trackpad.
When i turn on the device i get the trackpad click for a few moments and then nothing, i tried 7 trackpads and 7 trackpad flats, i know all 7 are functioning okay, especially one as i use it for testing and DFU restore.
I inspected the whole board and everything seems fine.
Can anyone help me as i didn't fiddle with trackpad...

Question about UE60JU6800K backlight power.

by Gjackson

Hi all,

got my hands on a Samsung UE60JU6800K, initially it apparently had a bunch of white circles on screen which I confirmed was due to loose diffusers when I opened the set up and found a mountain of them at the bottom. The person I got if from stored the TV unused for a lengthy period after this so when I got it the backlight was completely gone. I took out the strips and almost all of the LED's have a crack on the yellow phosphor form the center of the LED outward, the ones that don't have this crack seem to work still (Maybe due to humidity after a long period?). Anyways I...
