At least for now smile.gif

The past few months poking at the fan on my SA750 worked great, now the fan refuses to spin at all.

Such a great monitor, but such a bad design decision adding a fan. Would of been better off with a power brick.

Speaking of power brick. When searching samsung parts for the SA750, they are selling a power brick adapter. Anyone think that might bypass the need for the fan to spin? Shot in the dark, but that would be wonderful.

Anyone have a direct link to the delta fan on samsung parts? Can't find it listed there.

No, the S27A750D doesn't have a temp sensor, it actually read the RPM from the fan and starts to turn off when there's no RPM signal. My "solution" right now was using an external 12V power source for the fan (cable into my PC) and solder the RPM signal (blue wire) onto the PCB. I think the Monitor doesn't use the full 12V for the fan and thats why it doesn't spin up.

A more permanent solution would be buying a new fan:

Hello there!

I got my friend's S27A950D with a problem he could not solve. PC detects the monitor just fine but there is no videosignal, the screen glows in a strange way. I'm attaching 3 photos. 1st - general view. 2nd - left side. 3rd - right side. Have anyone met this kind of problem?

If it was mine I would take it apart and clean the contacts on the ribbon cables, specifically the one going from the main board to the LCD panel. If that doesn't help I think you are looking at a bad main board or a bad LCD panel. If it was a TV you might have a bad tcon board but most computer monitors don't have a seperate tcon board - it's usually a part of the panel.

This morning one of my 3 S27A750D monitors started turning itself off every 10 minutes. Some searching lead me to this thread and thanks to several posters here I was able to pull the base off, clean out the fan, and now everything is working like it should. Thanks everyone!

In response I went digging for a service manual. I eventually found a Chinese copy and translated it with a Microsoft tool, leaving a pretty pooly-translated and roughly-formatted document which you can find here: http://docdro.id/xejy7ND

That's odd - it expands out to this, give it a shot: https://www.docdroid.net/xejy7ND/samsung-s27a750d-service-manual.pdf.html

Also, my power light is blinking again this morning so it looks like I'm going to need to order a new fan frown.gif

Fortunately, another poster here has already provided the link so I should have what I need to get this done! Thanks everyone.
