Repair of the instrument panel VOLVO BL71B. The panel screen does not light up.
In the video I tell and show the process of repairing the display of the instrument panel of the excavator loader volvo bl71b.
The malfunction was that the screen backlight did not work. There was an image, but it was difficult to see.
I disassembled the instrument panel, got to the screen backlight and found the cause of the malfunction.
