Hello, the internal monitor of the MB1 no longer works black screen.
During the summer contest the screen is blinking and black screen.
After several starts, nothing is still black screen.
So I plug a monitor into the hdmi port and the miracle it works. After restarting, sup key and enter the bios, panel type 1280X800 / 24bits / single channel ok save and exit and restart. Once the hdmi screen remove and restart always black screen. Test in windows to switch to the integrated screen and nothing on the mb1 screen. Just when I start up I see the mark of the mother card displayed and nothing more afterwards. Being out of ideas I come to ask you if anyone has already had a problem. Thanking you F4CRE.

Suggestions that might or might not help:

Have you tried updating the graphics chip firmware to the latest version?

If you have not, go to www.intel.com/content/www/us/en/support/detect.html and download the Intel Driver & Support Assistant and let it scan your MB1 computer.

If already done without success, next check Windows settings for displays: correct resolution, using extended desktop when using multiple displays or making it main display when using it alone.

Are you sure that the video card resolution is within rage of the internal display:

You could in windows device manager try removing the internal display and letting it re-find it

Or removing the graphic card driver ( possibly the driver has become corrupt or returned to the native Microsoft driver) instead of the actual graphic card shut down and reboot ( make sure it does a full shutdown not a sleep mode restart)

Another test you could try and forcing windows to do a safe-mode start , this would not load the drivers for some of the hardware like the video card- if it has a display then, I would venture to say the device driver for your graphic card either needs updated or has become corrupt, get the latest driver for it and do a re install

Good morning everyone and thank you for your answers.
Indeed I did not think of the safe mode, and also see the side of the drivers. So I will adjust the display of the screen.
I would like to inform you if this will resolve the problem, thanking you again soon 73'S F4CRE. :D

Hello, here is the news of the day. This morning when the MB1 starts up, the screen is functional again without any intervention on my part. So I am surprised, but after 2 minutes two functioning the screen is put again to flicker. So stop mb1 and restart the screen works very dark mails more brightness. I suspect the backlighting has a problem. So what to do? Leave as is or replace the defective part if possible. See you soon for other 73'S F4CRE news. :wall:

I would tend to suspect the LVDS cable. This connects the Panel to the motherboard. The cable is shown below. Note the diagram is owned by Expert Electronics who have Copyright and is displayed here in case you personally can use it or need to forward it to a technician.

But I think there is a limited amount that the owner can do. It may be that there is a poor connection between the cable plug and the motherboard in which case you can try to clean the pins and re-seat it. If it is a broken wire it is a bigger problem. If the fault is at the Panel, I would say that only a qualified service technician could repair it.

hello and here is the news. Indeed the connector was only half engaged, great idea once reset normally starts the screen works but the brightness was not stable.
But it works a big thank you to you for your support I would make it work with a remote screen so as not to wear out the main monitor. Thank you again 73'S from F4CRE, looking forward to getting in touch.
Ps: in windows the screen and indicate internal screen is this normal, or it must have another name. :good:
