Hi everyone,
I'm trying to fix a Viewsonic VG2230WM-3 with no power. I replaced 6 bulged teapo 470uf 25v with brand new Rubycon capacitors and nothing change. The only new thing that has emerged is a ticking, like a clock, clear and regular.
I checked few things with my multimeter.
I have 165V at the big cap
To the right on the power board, to the logic board i made 5 measurements and here are the results:
BL-ADJ : 0.5 V not stable
GND : 0
GND : 0
+ 5 : 1.2 v to 1.5 v not stable
+ 13.(something unreadable) : 0.1 v to 0.3 v not stable
Below is the picture of both side of the power board.
Thanks for your help.
