Question Question regarding screen replacement

[SwedishGeek33]

Hello

I have a MSI Katana B13V laptop which the screen has been scratched i bought a screen replacement. But the problem is i dont know if i have to disconnect the ribbon cable on the motherboard before replacing the screen. I removed the battery and adapter and hold the POWER button for 1 minute for power drain. Is that enough or do i need to disconnect the display cable on the motherboard also? Because on my other laptop the backlight fuse got destroyed which resulted in just a black screen.

You shouldn't if the cable is detachable from both ends.

Moved thread from Displays section to Laptop Tech Support section.

Alongside doing this work, are you wearing an anti-static device?

Almost certainly. If its not plugged into power, the battery is disconnected, and you've held the power button, there is no power left to cause you an issue

I would recommend looking up a service/repair guide for your specific model of laptop, as they can probably give you a clearer idea of exactly what is required for this repair through pictures or a video. Generally, however, you would only have to remove the display cable on the LCD side and undo some screws underneath the bezel.
