Re: Dell 1707FPt No Power

Don't have any pictures of new board yet, it's exactly like my old board, only with all KY caps.
AC voltage bounces very little, between 123.2 to 123.1vac.

Re: Dell 1707FPt No Power

retiredcaps, it seems I reported these voltages in error. Testing again, in min/max mode, I record a neg voltage when ever the output voltage is stable or not. Don't know where to go from here.
