Hi guys, I'm hoping you'll be able to help me fix the PSU in my Dell 3008wfp monitor.
Symptoms: Will occasionally show a picture for about a minute then go blank. After this the screen will come on again each time and then quickly go blank (1 second). There is no picture and no backlight when this happens but the power light stays blue.
I have confirmed it is definitely the PSU at fault as I've temporarily replaced it with a known working PSU and the monitor works perfectly.
I have read the 3008 Schottky mega thread but I'm not sure it's the D22 diode that is at fault in my case as the power light stays on and it does come on (more like 2 seconds to black). The monitor is not dead to the world in my case.
All components look healthy with the naked eye and Nichicon capacitors are used on this PSU. I thought maybe it could be a dry joint but my untrained eye couldn't find anything suspect.
What can I do to fix this? I have soldering skills but only a lowly standard multimeter.
Many thanks for any help
