Re: Dell U2413 turning off
PS1 is stable at 5.37VDC. I can't get an accurate reading for PS2 (was hovering around 2.9mV) and PS3 (hovering around 1.5mV), and now the LCD panel is not working, but the buttons do light up, and the output of the main filter cap is now only at 348VDC.

Re: Dell U2413 turning off
Update: After it turned off, I immediately put on a fan pointed towards an SB20100 (Schottky Diode, according to its datasheet, within the "main switched power supply" circuit, with its own heatsink) and just after a few seconds, the monitor turned back on.Last edited by dcdcc; 04-26-2018, 11:05 PM.Leave a comment:

Re: Dell U2413 turning off
Yes, between the two cap legs.
PS. What do you mean by OVP circuit? Thanks...Last edited by dcdcc; 04-26-2018, 09:56 PM.Leave a comment:

Re: Dell U2413 turning off
So I powered up the LCD with its guts open, plugged in to a video source -- been waiting for it to turn itself off to check voltages, but it's been an hour and a half and it's still running fine. Man, this thing won't let me troubleshoot.
@budm -- voltage from the main filter cap was steady at 427VDCLast edited by dcdcc; 04-26-2018, 08:35 PM.Leave a comment:

Re: Dell U2413 turning off
I tried disconnecting the side usb board -- no luck. I've yet to check the power supply pins, though it sucks that there's no labelling on the board....Leave a comment:

Re: Dell U2413 turning off
Took a couple of images of the disassembly and board, for those looking for references, or who might encounter the same issues:
The caps are a mixture of CapXon, Sus'con, and Elite caps, not sure if they're reliable though....Leave a comment:

Dell U2413 turning off
I recently bought a used Dell U2413 monitor. All is going well until after a few days, the monitor started to shut down on its own. This would happen 30mins to an hour after turning it on -- the behavior is like it's pulled from the AC plug -- no power LED, and pressing the power button does not work. It would then take a few minutes for it to turn back on on its own. Sometimes, it would shut off again within 5mins after turning back on. I noticed that the room temperatt
ure contributes to the issue. When used in a cold room/environment, the monitor works fine. Also, the monitor has four... -
