Hi, I need help to identify the component with marking "9003 KAUCHB".
A bit of background...
I have an induction hotplate UNOLD Elegance Typ no. 58105 (with board CHK-A1.42S) which has a blown resistor.
I have also located the problem in the SOT23-6 component with the marking "9003 KAUCHB"; the pin 5 was disconnected from the IGBT emitter (ground) due to the high temperature and this caused the IGBT to be permanently ON.
I replaced the resistor and resoldered pin 5 of the SOT23-6 component to the IGBT, the hotplate worked for about a month and...04-17-2024, 12:55 PM -

This might not be a very popular request, but for the past few weeks I've been looking into how i can change the bios boot image on my Haier Y11b 2in1. From what I've learned, the image is broken down into a hex pattern which is supposed to be pretty difficult to find in the bios file and replace with a custom one.
The laptop that im planning on making this change was provided by the government and therefore shows the governments ugly logos and all on the boot screen rather than the manufacturers (Haier) logo which has got pretty annoying over the years. If someone can help me with this,...Today, 10:13 AM -

Hello everyone,
I'm trying to fix a small LG TV with wierd issue.
So I check that the display is OK by fashing a lamp at the screen. LCD is okay OSD is showing up.
Now since the BL is dark, I disconneted the BL from the mainboard and I injected voltage to it with my blacklight tester.
The BL turns on, the tester shows around 80V. So the led strips are okay it seems.
Now I started to suspect the BL driver IC which is a MP3378.
I have a donor board (dead cpu) with the same IC, so I swapped the driver IC but it did not solve the issue.

Hi all,
Recently picked up this GTX1650 at a local flea market for a low price and wanted to use it on my secondary PC. I first tested the card and saw the fan spin for a split second and then nothing. Immediately I thought of a short circuit. Disassembled and found a shorted SMD capacitor, injected voltage into it (1V/4A) and two Mosfets got hot immediately (QN3103 & QN3107). Desoldered these Mosfets and the card turned back to life.
Bought replacements from Aliexpress and replaced them afterwards. Tried the card but still the saw the fan spin for a split second...Yesterday, 03:15 PM -
