Re: Viewsonic VX2235WM - blank screen on/off
One thing to note that even if the capacitance values measure within 20%, the ESR value is more important. Therefore, if the cap value measures okay, but the impedance (ESR) value is too high, it can cause the cap not to perform correctly causing the problems you see. You need an ESR meter to measure the ESR value for each cap.
