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!Today, 11:13 AM -

Most Displays I have worked with are of course LCD Or Blueish Fluorescent Types. I Have a Marantz PMD800 tuner with sort of a white display. The display area is a sealed rectangular shape in a Glass Case. Looks like some sort L.E.D. display only not your typical section number type. I picked up this Tuner cheap as the display is very Dim. In front of the circuit is a dull red Plastic lens.
The display is very week and hard to see. I've got my DC 5 Volts allover and also a DC 32 Volt that runs some other section. Power supply looks good front to back. Not familiar with this type...06-07-2024, 07:19 PM -

Hi,
as noobie to this please excuse my lack of experience.
I am trying to remove a BIOS password from this machine:
[B]HP ProDesk 400 G6 Mini [/B]
but so far I still have no success.
I bought [B]CH341 programmer[/B] and decided to give it a try.
The programmer came with [B]8 pin [/B]cables and connectors or whatever everything else is called so I had to buy a new [B]16 pin cable[/B] because the chip which I think is the BIOS is with [B]16 pins[/B]..

Hi! I was given this TV. It would turn on fine but then after a while the BL would shut off while rest of functions would stay working. I assume this 99% means a shortcut in the BL so the PS detects the overcurrent and shuts off the BL pwr.
I managed to keep it up for the time enough to enter into settings and turn down the backlight to 50% which seemed to help. I was able to watch it for some hours several days
But the other day, I went to try it and the BL didn't even start at boot up. I want to repair it but: This is a spare TV that I want to keep at a house that I seldom...06-03-2024, 12:58 PM
