Title:

Dell U2413 turning off

Text:

I recently bought a used Dell U2413 monitor. All were working fine within my initial use, though a few days after, the monitor started to turn itself off randomly within half an hour to an hour of use-- no power led, and would turn back on after a couple of minutes. After some troubleshooting, it appears that the power supply, or something within the power supply circuit is overheating, thus causing the monitor to turn off.

I'd like to know what specific components to look into for this kind of problem?

Thank you!

edit:

Currently tinkering with the board and I'm looking at two mosfets that might be overheating. I checked with the multimeter and they're both around .450-.470v.

K15A60U (with its own heatsink)

LD7904jgp7 (no heatsink, and near the K15A60U's heatsink)

Still not sure though which one needs to be replaced.
