Green Amber light ok ? No Power, No corrosion, No spill, Clean board. Customer claims it simply refused to start.
Sorry if it seems I am all over the place....still at an early stage repairing boards and I've been trying whatever I could find searching the forum.
I tested the following Rails and test points but am at a standstill. Any advise where to test next ....TIA
