Hello, I have a customer who updated his bios on his GT72-6QD Dominator G series, He flashed the newest bios (even tho it said first upgrade to v10) But now the device powers on, the fans are turning but nothing more, no image. I tried to download the BIOS from the website and flash that using CH341A Black (GD25B64CISG chip) but still nothing, can someone provide me with the correct bios to flash on the device? Thanks!Yesterday, 06:14 PM

The original dump was lost in the previous service, the bios chip is empty(
An F1 engineering dump would be ideal

This motherboard has two chips one is UC4 -> 16MB which contains the main bios without the me inside, in fact if
use ME analyzer to check, it returns (see pics) "file does not contain intel engine/graphics/indipendent firmaware".
The second chip is UC2 -> 8MB, it contains ME data (see pics) and other things like PMC. If there are problems
like power management or ME, the chip to be rebuilt is UC4 and not UC2. Anyone confirm this?
I unzipped the exe file via this guide on the official Lenovo website

I have a Panasonic Lumix GH5 that I replaced the screen panel on. Attached is a photo of the new screen bought off Ebay and sent from China. First is with the lens off and camera cap on, and the second is with the lens on. The problem is there are vertical bands on the sides, fuzzy electric noise, and the image flickers. The camera also has a EVF, and the image there is tack sharp.
Seller says it is most likely a circuit on the Main Board, but my experience is this type of issue is usually a cable or bad display. I have cleaned all the cables and inserted them under my scope....Today, 04:29 PM -

Hi All,
Thanks for reading. Based on the interesting fact that the vertical lines issue don't seem to effect the menus whatsoever but rather everything around the menu regardless of video is shown, I'm trying to set mine whether the issue is the main board or the t-con board.
Again what's baffling is that the menu is not effected whatsoever. However, any other video displayed regardless of inputs or when no inputs exist exhibits the vertical lines and seem to effect black areas only.
The lines are green in color when the tv is in "Game Mode" and...05-12-2024, 10:52 AM -
Hello everyone from Italy, I'm here to ask for help on a Vestel TV, I've had a Vestel TV branded "XD" with a broken screen for years, but now I've found a Telefunken (still Vestel but older) and I've mounted the panel on the "XD" TV, it works, but the screen is upside down, given that Vestel does not allow you to rotate the image from the service menu, does anyone know how to solve the problem? the original panel is marked ves315WNDS-2D-N12 while the main board 17mb110, the panel I mounted instead in the tv (from the telefunken) is a ves315WNDA-02. ... It is not worth repairing...05-12-2024, 05:22 AM

there is no reaction, it hangs at 20 V/0A. There was a little corrosion in the u7650 area. Replacing the u7000 did not help. Tell me, what else could it be? PPBUS_G3H=12.9V
Flashing the bios with a clean region also did not work!05-06-2024, 04:31 PM -
After upgrading the factory 128Gb SSD to a 512Gb WD_Black SN770M, this surface pro lost touch on screen, no touch in windows or in UEFI.
The Human Interface Devices did find touch and stylus but it shows Disabled in windows device manager.
I am not sure if this is a bios problem or hardware problem, already tried reinstall and reset from windows, not working. And now trying to clean/reset the bios.

Hello,
I have a MacBook Air 13 inches 2014.
I have set a EFI password and I can't remember it : now I want to reinstall macOS and I can't because the MacBook is asking for the password.
I know how to remove the password with a usb programmer.
I plug the usb programmer to the motherboard and to my pc with usb, I read the EFI and I save it to a file.
Then I have to find this value in the file : $SVS because it indicate where is the password.
But I can't find the value.
I have attached the file
Thank...Yesterday, 12:10 PM -
Hey guys, I have a Lenovo Ideapad 320-15ikb NM-B241 rev:1.0.
After turning it on, it runs for a few seconds then shuts off completely. No screen, no fan. After shutdown, a red light comes on and off fast. I've been trying to troubleshoot this for days now. It's never been opened up; the Lenovo sticker is still intact.
(!)I tried with a different BIOS battery, without any ribbon cables, on battery power, without the keyboard, and it's always the same.
Any insights on what might be causing this?...05-13-2024, 03:05 AM -

When plugged in (no battery installed), the battery light on the motherboard lights up and then turn off. When powering on, the same and light and the power button also light up in a white color but no output on the display. It stayed like that for a few seconds before shutting down. I also seem to ruined a connector that connects to the WLAN, 2 USB and audio board, the same board also have a melted 2062A IC. I will post pictures in the reply section05-11-2024, 04:40 AM
