The laptop I am working on is RAZER BLADE 15 , RZ09-0369, the motherboard is DA560 VER 4.0. The original fault was it powered up with keyboard rgb on and no video on screen/hdmi.

by Jedi134Hi I have inherited the above desktop scanner, all seems to work correctly but there is no sound output. The only sound I do get from the speaker is the beep confirmation when you press a key. No output from the headphone socket either. Not even radio static with squelch fully turned down, tried a reset by holding 2, 9, and hold buttons but still no sound, does anyone have any experience with these scanners, thanks.

by Raulnngood night! I have this TV, with quite poor build quality. It has a tcon integrated into the panel, a single flex from the tcon to the panel, and the 2 panel controller boards joined by glued flexes. There is no way to separate them.
The symptom is that the image is not visible, but the backlight works. How to know if the problem is in the main or in the tcon-panel? I can't override zones.Yesterday, 02:11 PM -

I picked up a faulty bench PSU that was being discarded as was faulty. So the internal SMPS has some faults, bad thermistor, Schottky rectifier and Mosfets all blown and I have replacement parts on way. fingers crossed 😀
I am looking for a set of diagrams for the power supply. has EST v1.15 along with 2022 date. Not sure if the EST refers to Edwards or some other manufacturer.
thanks in advance.

by ritaloHello,
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...-

by NagyeszHey 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 -
by E--ManHi 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...5 Photos05-12-2024, 10:52 AM -
by Kg74I 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....2 PhotosToday, 04:29 PM -

by tuankietkietWhen 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
