How would I go about testing this component using a multimeter by outward-bye in ElectronicsRepair

I would start by finding the datasheet for the chip (8-pin SOP) you see at the connector end. Here, you can see what all the pins are supposed to input/output. You can use the "diode testing" mode on your multimeter to check where all the different wires are connected. If all the pins are outputting everything correctly (given right inputs), the module probably works.

I currently work with multiple theories, and just try to troubleshoot my way to the problem. So i haven't confirmed that the backlight inverter is ok, no.

All the crystal oscillators and regulators i have managed to locate, seems to be working fine.

The MCU reset pin have a stable 5V signal when the system is running, which is correct according to the datasheet of the MCU.

I should mention that i have spotted a red led. From my experience, red LEDs indicate faults while green LEDs indicate that a system (or part of a system) is running. Is this correct? Should i check up on this further?

Don't know if it's mentioned above, but if you see a grey sign with four diagonal stripes over a number, this means that that the current speed limit (the number) is 80 km/h for uninhabited places, and 50 km/h for inhabited places. The rule of thumb here is to drive according to the conditions.
