hi everyone i hope you all doing well.
i'm trying to replace a sim socket in my 4g router, i found similar parts on aliexpress and i'm not sure if it will work on my device (Huawei b593s-22)
here's the original one:

Hi all, just curious if the BL_ERR signal is active high or low? TV has the 6 blink error code and I've changed the backlights as they tested questionable (4 strips tested - 203VDC, 203VDC, 203VDC and 175VDC). The new strips all tested at 175VDC. Now when I turn it on, it tries twice to come up and then the 6 blink code. During the this time the BL_ERR pin is high and drops low momentarily, then does it again on the 2nd try to boot (so Im assuming active low). The other thing is the backlight voltage ramps to ~280VDC from around ~160VDC and then back down as the TV tries to boot again. Does...Yesterday, 07:30 PM

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 -
See attached picture. I have a Fluke T100 Voltage Tester that the resistance and diode measurement isn't working (it's not the batteries (as I have already checked them and put decent Duracell 1.5V AAA batteries inside it).
I have looked on the web for any information and on youtube without any results for this model.
There are no screws visible or anything obvious. So I am hoping someone here has the solution to take it apart?
The only way I can see is underneath the yellow rubber handle area, however I don't wish to damage it if it isn't the case!...Today, 07:21 AM -

Hello,
I post this in this section for a Dell Inspiron 3477 All in one as the motherboard is more close to a laptop one.
So, the issue is that whatever adapter I use, I get this screen when it starts up. I tried aftermarket adapters and original HP adapters, both 65W and 90W. Minimum requirement is 65W.
I don't have its authentic Dell adapter as I took it for free in case I manage to repair it, but the HP ones I think are pretty much identical.
First thing I checked is if the dc jack on the board has an issue but with the MM I see all three pins, ground, 19.5V and...Today, 10:52 AM -

Hi!
MSI B660 MORTAR MS-7D42
the problem start when the client broke some capacitors and resistors in Back of the motherboard under PCH
i put them back but
same thing
motherboard power on with no display after press the pwr button power on with dram led and restart and power on again with red cpu led
cpu vcor looks good no short and cpu heat up but after second restart not heating
i found 2 shorted transistor near to KBC but i doubt if that normal short or not (connected to AGND AND AMDSIC)
other technicien flash the bios but same thing ....Yesterday, 12:45 PM -
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 have got an Steeldigi Steelshock 4 v2 controller won't draw any amp from outlet.
I have disassembled and removed the battery. I have tied to measure some points. The usb connector shows 5 volts. There are test points and shows 5 volts everywhere it should. The battery connector in diode mode shows 0.009v is it ok?
There is an U4 chip place, but no chip, between the battery connector and the charging port.
How should I progress to identify the problem?
Can anyone help me with this?...Yesterday, 11:20 PM -

So I have this ASUS K52JK which cpu overheats seconds after power on even while idling at the bios menu. The laptop works although it does throttle the cpu.
I was attempting to clean the bios and accidentally lost my original bios dump.K52JR found on badcaps does work but has the same issue with cpu overheating.
Can anyone post a bios dump for this laptop?
