samsung monitor 750s model dt17ls7l

I have no power with this monitor.... fuse good horizontal output appears good with ohmmeter check... the power led does not even come on for standby... seems like a power supply problem but not sure .... Yes im lazy was wondering if anyone had any repair tips for this model before i get way in deep on this sucker.


Disassemble (tricky!) and clean contacts or replace (easier) the SW601. This few models of this period including yours had short-term bunch of iffy switches and solution was replace or clean it.

AHH HA!!!! it was not the switch ..... there is a 180k ohm resistor (well 2 in series) connected from b+ to the vcc of the driver IC for the transformer. One resistor went open. No burn marks on it at all.

i think it was resistor 509 if i recall.
