by ShadXoHi everyone,
I have a HP Elitebook 650 G9, where I made a dump.
I found on the internet that I need to edit the EC Bios. Something starting from Active till blank rows, which worked for a 840 G8 the guy was using, but didn't work for mine kept getting the 903-Computer Cover error.
It was worth a try and now i'm also stuck here after the 903 error it goes to the screen to enter the admin password.
I wonder if someone can help me with the edit of the dumps...-

by x_orange90_xI got this tv yesterday and it shows a screen full of colored vertical bars and horizontal lines that move, change, and dance around. When the set is powered on there is a slight buzz from the tcon. I removed one ribbon at a time and this was the result:
Right side connected, left side disconnected = half image on right (somewhat distorted, see photo attached) white screen on left. NO buzzing from TCON
Left side connected, right side disconnected = right side black, left side white with distorted horizontal lines near top of screen. Buzzing from TCON

by mosfetratusWhen i fully shut off mac, orange light goes off and wont react to power button. I have difficult time resetting with combination "shift+control+option and power button", because it rarely works (reason unknown), when i manage to get orange light and then press power button macbook wont turn on and orange light goes off. When i hold combination with power button it turns on, and works fine if put it to sleep mode.
Works with battery and charges, but when i shut off i get this problem.

by mrsithHi 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...4 Photos06-06-2024, 09:11 AM -

I have a board that does not turn on and I found this integrated damaged but I cannot find the part number, I looked for a schematic but there is none. What I could see with the microscope is that it has these letters "THDN BCD" but I couldn't find any information, I'm sorry for the quality of the photo but my cell phone can't handle it anymore. thanks1 PhotoToday, 02:10 PM -
by greenchigoHello, please help:
After replacing motheboard i need to transfer DMI data (Product Name, MTM, etc) from old bios backup to a new EFCN59WW for flash it by CH341A
Everything is works but in BIOS and in Legion Vantage software s/n and others are INVALID for now. So... I want to flash and fix it.
Also question is:
Does I need clean ME or something else or I just can "copy-paste" offset 00532000-00533FFF from backup bin file to current dump bin file and than flash it to chip or... not?

Just starting out in electronics repair and teaching myself as I go.
I have here a Corsair RM650 ATX PSU, which I'm treating as a learning project that if successful may be used in my PC.
Fuse was blown, probable power surge from lightning, followed the circuit and found, a dead relay and all the diodes and resistors around the bridge rectifier shorted. Rectifier and MOSFETs seem fine on the LCR.
Also found these tiny diodes on the other side, a few shorted, the rest seem fine. But they're not all marked as Zener on the pcb. So I'm unsure what these should be replaced with....Today, 09:52 AM -
by marcinas1983Hello! I have a similar problem as the author of the topic. I'm starting to learn how to repair electronics. I bought a damaged Zotac GTX 1060 3GB graphics card. I measured what the author of the topic measured and I attach a photo. The card core is slightly warm after power-on. Does anyone know what could have been damaged?

I'm trying to extract a flashable bios file(ch341a) from the lenovo bios executable download. I have tried the instructions from this site [URL]https://starkeblog.com/lenovo/uefi/2022/08/28/extracting-bios-image-from-lenovo-update-exe.html[/URL], which are not working. According to those instructions, after issuing the command [CODE]"innoextract 7wcn38ww.exe"[/CODE] it should create an \app folder, inside which, I should find a newly created "7wcn38ww.exe" file. I should then be able to extract that using 7zip and find my .FD file.
The trouble I'm having is that...-
