About :

When trying to turn on the Prology DVS-1120, there is no backlighting of the keys and no image on the display. The culprit is the faulty transistor Q115 2sa1273. We replace it with a more powerful Soviet analogue KT816. When turning on the Prology DVS-1120 without a disk reading unit, we get a blue screen.
