Potential problem diagnosis for CB3-431 very dim screen
Hey folks,
I am asking a question in order to possibly gain a bit more insight into the possible problem with my CB3-431 Chromebook. Whilst using it I hit the area to the right of trackpad: fairly hard (was heat of the moment kinda stuff hah) and the screen suddenly went very dim, almost black, but possible to see if you looked in closely/held a torch up to it.
I've tried taking to repair shops several times but have been unsuccessful due to lockdown closures/impending lockdown affecting spare parts delivery. Been looking into possibly buying the necessary parts and repairing it myself. I would have pretty confidently assumed that it might be a problem with the backlight or inverter but since these parts do not seem to be in the general region I hit I'm wondering if there's a possible other explanation for this problem?
I have connected it to an external monitor via a HDMI and the screen brightness is fine for the external monitor.
Thanks in advance for your answers.
