I think, reset can't help. Board have some black holes. Corrosion damaged plating holes. First of all test contacts!

I think, it will be usefull!

... For measuring, will be better to use diagnostic diagramms for control points.
It`s wery hard work to measure every elements. U need separate/measure/put back.
