Hi, everyone!
I've recently acquired two brand new SPI chips to replace the one currently in my Acer A514-54G laptop MB (FH5AT LA-K092P). The reason why I'm replacing the current SPI chip is because I had some difficulties with a third-party IT assistant who pretty much lacked the soldering skills and ended up destroying the current SPI chip soldered to my MB from factory.
I've decided to do this on my own because I spent the past month or so learning some soldering skills and BIOS modding through Badcaps and WinRaid forums, hence the attempt. I've also chosen to buy... -
Hey guys, I need help with my personal MSI GP62MVR-7RF. Annoying fan / thermal issue.
Machine Idle. Fan will spin medium speed for 4 seconds, then off for 1 second. Repeat forever.
CPU and GPU are cold. No load, just sitting doing nothing.
It's clean inside, nothing blocked. New MX4 paste.
Updated BIOS, EC, and VBIOS but nothing's helped.
Schematic shows 2 thermal resistors, but they're OK.
All thermal signals are good, inc PCH.
Has anyone ever come across this ? Any idea what to do ?
Could it be a faulty CPU / PCH / KBC ? I REALLY don't want...09-16-2024, 02:14 PM -
hi guys,
My 5 years old SAMSUNG QLED got color inverted somehow. I have tried reset, replace mainboard as well as the driver board without luck. The issue must be on the circuit on panel skinny board or so. For this model I could not find the dedicate T-con board so AS15 replacement is not applicable..
I have upload the pictures
Maybe I should measure the gamma voltage but I couldn't find the right place.
Any idea would be appreciated.... -
Hello guys,
Got my hands on this laptop and started troubleshooting. The only thing I know is it turned off and never came on. No lights and not coming on.
Started doing some checks and found the main rail present everywhere. Something weird though as the gate of the first input mosfet is 3.7V and the output is 20.3V.
Tried to trace the gate and it looks like it's connected to pin 61 on the io. Is the IO supposed to monitor the gate voltage?
5V and 3.3V are missing from the coils. Found by lifting PL6202(on the 5V rail) the clicking fet sound goes... -
