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 France_53Hello 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

Hi.
I kindly ask you to help me solve the problem.
Dell Precision 5510, motherboard AAM00 LA-C361P Rev:2.0
The board turns on, there is no image.
Read more. When the power supply is connected, the front panel indicators light up briefly.
When you press the power button, the button indicator lights up. The board works
there is no image, there is no matrix initialization, there is no image on HDMI.
When turned on, the fans do not spin, but when they warm up they start spinning.
When you turn off the button, the fans spin up to full speed for a short...05-11-2024, 03:14 PM -

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.Today, 02:11 PM -

by AllgoneHello everyone, I have this Asus model X556UA that when plugged in I get the white light but nothing happens when pressing the power button. I've been looking into it following the power sequence and found out that the power button is sending the signal to the EC (PWR_SW#) but the EC is not sending the PM_PWRBTN# to the PCH (it always stays at 3.3V). I'm stuck here and don't know what else can I do, maybe I can get some help. I've seen that this could mean that the PCH is dead but I don't know how I can confirm this. Also this may not be important but when plugged in, the PCH/CPU (they go together...Today, 02:10 PM

by valente222hello everyone.
I need binary for Epson L3150, this printer is something special today. It happens that when you connect USB to the PC, it does not recognize drivers nor does the software even find it to load the emergency firmware again. The device only turns on and the power button LED remains constantly on. The head normally comes to its ready position but does not react to buttons or scan. I point out that I have also tried installing a new head, scanner or new button panel... but it is still in a vegetative state. Has this ever happened to anyone?...Today, 01:08 PM -
by RunlincHi everyone, the tv was in a continuous reboot cycle. To get the best screen image i can I taped the VGH and VSS pins on the left side buffer board joining ribbon.
I am left with a good image apart from the black horizontal lines that I cannot get rid of.
I cannot find anything on the buffer boards that has shorted.
Do you think there is anything i can do to eliminate the lines, or are they caused by an internal panel short and the image cannot be impoved.
Many thanks for your assistance5 PhotosToday, 07:40 AM -
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?...Yesterday, 03:05 AM -
by hexdyHello, I wanted to know if it is possible to modify a BIOS file to accept a legacy disk when it does not have the capability, I had this problem on a Optiplex 3060 that were donated to my job where we use non-uefi linux distros, we cannot use uefi since is a "big machine" with this systems beign the center of all of it, we can't change the distro now, maybe make some changes, but if I can modify the BIOS it would be awesome.

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
