Lenovo c940 Screen suddenly went black , NO display

2021-07-30, 5:59 AM

I was using my laptop normally, and suddenly went black and stopped working. I proceeded restart my laptop and screen was still with no display, i connected an external monitor and that display worked. I installed all the updates and everything, checked all the display and monitor drivers and all was to date. Really don't know whats wrong please help me fix this problem. i even did the diagnostic check on the website but said everything was working fine.

The external monitor can display normally, indicating that the motherboard and graphics card can work normally without problems. The fault may be in the LCD panel assembly. Most of them are caused by severe oxidation of the screen cable connectors, resulting in poor contact.
