Re: Samsung 933SN - 2sec on, then off

7 out of 10 that circuit circled in red to the left is what's the cause of the issue

if you have not done so already try what nomoresonys has said "well, start by testing the connector on power supply for expected voltages, theres a label with expected voltages right by it, do you have a digital mutimeter?"


that will help diagnose the issue faster

Re: Samsung 933SN - 2sec on, then off

I have the same monitor and have exactly the same problem, turns out this model is common for going wrong like this. 1 of my surface mounts had fell off which caused other issues but now installed the monitor works apart from that same issue.

more to a description, the monitor lights up and powers on perfectly fine tad slow on start up, this is just wth power lead, as soon as I add the vga cable the monitor shuts off, bare in mind that's before connecting to the pc, as soon as I connect to my pc the screen then shows my desktop...
