I have two of these microscopes, both take power and the lights for the specimen bed light up but there is not signs of life on the screen, I have checked the power button for the screen and the screen is getting power.
I need help identifying some SMD components on the board
For the first one has a model number of 44348 there is a three legged component (transistor/mosfet) with the marking N011V (Q4 AND Q5 in picture)
The board has several numbers on it but they do not show any meaningful results on Google and I can't seem to find schematics for either of the boards (they...Today, 03:18 AM -

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

I waited 5 days for this to arrive only to find it's not the right model! Rather than wait for a China order, I was wondering if anyone knew if it was possible to cut and splice/solder anywhere?
12 pins vs 10 pins, it's a for a Dell AlienWare x15 R2 (P111F003) and the one advertised on eBay was Dell Alienware 15 R1 R2 R3 AW15R1 AW15R2 DC IN Power Jack 0784VK DC30100TN00.
Also, there seem to be 4 wires soldered to the back of the jack on the X15 R2 and only 3 on the 15 R2. What would the 4th one be?

Hello. I have problem with Dell psu, outputs are ok but it does not give power ok signal.
It has a secondady board with wt7527s to check inputs. It doesn't give PGO because it doesn't take enough PGI.
It takes PGI from a voltage divider.
I draw a schematic for you to understand.
My first question is why 5v use two transformer pins, while 12v uses only one.
My second question, is pin 2 in transformer weak? After resistor, diode and voltage divider, result is 0.7v instead of 1.2v, so wt7527s does not output PGO....05-20-2024, 07:33 AM -

I have Asus Z170 Pro Gaming motherboard, it's working fine apart from the reset and shutdown commands. It doesn't restart when exit the bios or choose to restart in the operating system. Shut down also doesn't work, everything works normally until the moment it should turn off. The only way to turn off is by keep pressing power button for a few seconds. What could it be?

I get backlights that stay on not there is no image. The tv does not automatically power on when plugged in either which I generally see happen when there is a fault. It responds as it should to the power button.
I checked the test points on the TCON and I have proper voltages except for at 1P15V. I don't know if that is supposed to be 15V or 5V, but either way I only get 1.134V on that point. I have 12V, 8V, VCC, and a small amount on the CKV point.
I tried heating up the SoC on the main board but that made no difference. Disconnecting either ribbon from the TCON also...06-01-2024, 08:55 PM -

The HILTI CPC battery flashes green but no tool starts or works. when testing the battery has 19.2v what could be the problem with them because I have three similar ones but there is nothing written on them all the patches are removed in the first B22 /4.0 with 19.2v the second one B22 /5.2 with 21.8v the third B22 /4.0 with18.3v are all three destroyed ? a bit difficult to believe have also tried other Hilti tools the same thing if someone who can help very grateful...Yesterday, 08:05 AM
