Question about Soyo Dymond DYLM017A 17" LCD Monitor
I am looking to find the polarity of the DC adapter on my 17inch Soyo monitor. Any help on the plarity or replacement power supply source out there?
Normally, the polarity is molded next to the connecter hole; it may not be real easy to see.
If you have a digital multimeter with a 'diode' position, most devices have a diode internally installed to prevent damage in case of a bad substitution and the meter will show a value of somewhere between 500-800, typical would be in the mid-600s.
If you find that, then the meter is currently causing the internal protective diode to conduct as it would if the WRONG polarity would be applied and most meters will supply a positive voltage to the red lead for diode function.
Commonly, the center is the positive contact but this sure isn't certain.
