Dell 3421 Random Display

11-18-2020, 05:06 AM

Hello all,

I have Dell 3421 12204-1 DNE40-CR MB.
Sometime display comes and works fine. Sometime no display no error code too.

Changed RAM, LVDS, Screen, DC to DC doesn't help. Voltages seems to be ok.

Any help is appreciated.

by TheQuentincc

Hi,
I have a Dell XPS 9300 that's working perfectly fine with an external display plugged, from windows the internal display isn't detected. At boot I can see the Dell logo then when it should display the boot/bios or whatever the screen goes black (no backlight, no image using a flashlight). I tried unplugging everything on the motherboard except the eDP cable but it didn't helped (so it's not the lid sensor). LCDVDD/backlight power are powered down when this happen, PANEL_BKEN_EC and ENVDD_PCH are also down to 0v. It's weird, it almost feels like the motherboard is shutting down the display...
