Hello everyone,
I'm currently working on a MacBook Pro A2485 and have encountered an issue with the LCD. Instead of opting for a full replacement, I'm interested in performing an in-depth repair on the LCD itself. I'm hoping to find the schematic for the LCD in order to understand its architecture and troubleshoot more effectively.
If anyone has access to the schematic or can point me in the right direction, I'd really appreciate it. My goal is to repair the components and connections within the display, rather than going for a costly replacement. I've been in the notebook...

Hi!
I kindly need your help with a DELL Wyse 5070 thin client which has locked BIOS settings (I want to change the boot order but I have to provide a password first). Is it possible for someone here to help me ?
I am attaching the original bios dump of the machine in question.
Service Tag: 5X1ZQL3
I would really appreciate any help.
Thanks in advance!...Yesterday, 02:22 AM -
I received this tv stuck in a boot loop and was able to get it working after letting it sit and reboot several times. Whenever I try do things in the settings it will crash back to the main screen, lock up, or reboot itself. I tried doing a Reset on it and after it rebooted nothing was changed. The Google account used was still present, and the downloaded apps were all still there. I can sometimes get further into settings such as setting up my wifi, not most times it will crash and reboot. I even manually removed the Google account and it CAME BACK after rebooting the tv. Before it rebooted one...Today, 11:29 AM

Ok so let me run you through the chain of events, the controller stop coming on no video, after checking the board they were lots of shorts on the board. I removed the screen a couple disappeared, then I removed the cpu and more disappeared, lastly I removed the memory chip and all shorts were gone. (The 2 chips circled in red are the memory and cpu) Also there is an issue with the 5v test point that is circled it’s reading 12v and so is a 3.3v regulator next the power jack.
Ordered a new CPU and Memory chip and installed them, reconnected the screen and all shorts are gone. Reconnected...Today, 12:08 PM -
This happened last Saturday and today I finally had time this morning before I went to work to replace two non brand capacitors
I will let you be the judge weather or not these are bad or not according to the blue ESR meter that I am using
I am comparing them to a brand new one that I installed
The display came back on and the programming was not lost which I was surprised by I would have thought that when the display went blank that so did the memory as well
I going to let it run for several days before I remount back on the wall next to the...09-05-2024, 06:48 PM -

Hi, can someone help me please with the removal of the bios password of this dump.
Someone desoldered the bios chip, tried several "methods" but with no luck, and he gave me the dump to try to search some help.
For now he deleted more things and bios password is gone but laptop doesn't show serial, model etc.
Also, I updated bios to latest version, when he will write the dump again without password, it should be better to put back the old version that was orignally or doesn't matter? Because from what I've read this laptop has 3 bios chips, don't know if has...Today, 10:40 AM
