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...

DELL IPCML-CT rev a00 pOWER ON PROBLEM

by Cicciotest

Hi everyone,
I have a problem with this dell mini desktop, no LED lights up and there is no response from the front power button. It literally feels defunct, with no feedback whatsoever.

IPCML-CT motherboard rev.A00
CPU: Intel Celeron G5900T

I tested the power supply (19.5v correctly) but to be careful I also used an alternative power supply to test, nothing. No LEDs, no power on.

I tested the power button pins and they correctly measure 3.3V, so when I press the button or put a bridge with a wire, the pulse seems to be there correctly.

HP ELITEBOOK 1040 G6 - SCHEMATIC

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.

I want to dim light bulb by 50% I want to learn how to calculate it on my own

by Omron

I have a 5W lamp on 12Volts battery, I want it to be half as bright, so I will add a resistor. What resistor should I supply?

A = W = 5 = 0.416mA
_ _
V 12

R = V = 12 = 28.84 Ohms (R) this is resistance of lamp
_ _____
I 0.416

So I will add one resistor 28.84 Ohms

I will have 28.84 + 28.84 = 57.6 Ohms

Or 28.84 + 28.84 = 14.42 Ohms

I don't know if it will work in series or in parallel
voltage would be 6V and amp current mA = 0.208mA We divide everything by two

W= V * I...
