I would like some help with this MacBook if possible. It came in with not turning on and the Magsafe light was off. After inspecting the logicboard i cannot find any liquid damage and also no burnt or shorted components.
took some measurement and i can see i have fluctuation on PP3V3_S2 and also PP5V_S2_MAIN amongst other rails. Using the thermal camera RC282 & RC283 were pulsing, but after removing these it was still the same.
I then did some investigation into why the rails were pulsing and noticed that P5VS2_PWR_EN (comes from U8100) is also doing the same thing.....

Hi everyone!
I'm currently in desperate need of a boardview for my acer laptop.
Make : Acer
Model : Nitro 5
Motherboard: gh51g - la-l181p Rev: 1C
It is completely dead with no power, lights or anything.
After inspecting under the microscope. I have found what looks to be a burnt chip (509EL)?
After countless hours looking online I cannot find a replacement.
If anyone had a boardview, and can also possibly point me in the right direction for a replacement it would be a huge help!
Thank you!... -
I have a Gigabyte 6-77-NH50HP00-D04-5C. The device does not start. I downloaded a BIOS file from another forum and installed it. The device started with the file, but cannot find an NVMe SSD in the BIOS. A data storage device on a SATA port or USB stick is detected. In the BIOS, the ME firmware version is 0.0.0.0. TPM is also not available. Here is my original BIOS. Can anyone help me?... -
I replaced the backlights all good. Two months later set was dead, had a shorted D9100, replaced all good again.
Now months later set powers up,backlights light ok,no picture. 12volts missing from fuse on tcon. 12VA on power
supply is 19 volts. Changed D9100 again, same, 12 volts measures 19. Am I looking at a power supply or mainboard
issue. Set will power up with remote but not power off.... -
Hello,
I have spent the last hour on this and I guess this is just over my head, so here I am.
I have an ASUS TUF GAMING Z790-PLUS WIFI motherboard here that needs to have the BIOS updated in order to accept the latest CPUs.
The BIOS chips seem to come as a set of two: GD25B64ESIG and GD25B128ESIG. My guess is one of them is a fail-safe for the main BIOS? I really don't know. Or one of them is ME and other is BIOS? I don't know.
Anyway, I took dumps of both chips and then downloaded the latest update for this motherboard from ASUS's website...
