I've acquired a marantz sx72 that doesn't work, looks like the power supply side is a fault but I can't locate a schematic. Does anyone have experience of this model?Today, 02:10 PM

hello everyone
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. thanksToday, 02:10 PM -
Hello, 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 00532000-00533000 from backup bin file to current dump bin file and than flash it to chip or... not?

I 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

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 -
Hello! 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?

Hello,
I want to fix a 2016 12 Inch Macbook which has a dead Logic Board.
USB-C and Battery section seems to work, trackpad clicks, but all cpu Voltages, (VCORE, CPUSA) are 0V, CPU stays cold.
PPBUS_G3H, 3.3V and 5V Rails seem normal. PM_SLP_S3_L is present but CPU_VR_READY is not.
Thanks for your help!06-10-2024, 11:13 AM -

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.

They brought the MacBook after another service and the touch ID doesn’t work, and it’s not surprising because the cable is broken. How to get out of this situation so that the touch ID works? who did it? I’m still thinking about repairing the cable, but it’s not clear where the information is stored, on the cable or in the sensor itself?

Hi guys,
Need some help again please.
I have a Dell 3593 that just refuses to charge, giving the usual adaptor warning.
The charger is original, and works on another Dell. The battery is the same story.
2 questions.
1. does a bios downgrade fix these issues
2. If not, please can someone explain in very laymans terms how I override this stupid thing?
thanks...Today, 12:38 PM -
hi all . I can't install the system. I've encountered this before, but I can't remember how to fix it! It cannot boot from an external drive (prohibition sign 🚫), but the firmware is not blocked! but it doesn’t connect to the server! The time is correct!
