DIY Project of the Day: Fixing a fan in my Samsung TV


Unfortunately, I had a rather tragic Monday.  There I was, sitting on the couch, watching Futurama, because Futurama is awesome.  Then got an error message on the TV:

My reaction, being the naturally cool, calm, collected person I am, was

NOOOOOO!!!!  F&%$ YOU FAN!!!!  I WAS WATCHING FUTURAMA AND YOU SHUT OFF!!!  DIIIIIEEEEEEEE!!!!!!!

After crying like a small child who recently lost their favorite toy, bottle, and pet on the same day, I thought it should be fixed.  Went to Samsung website (support orders suck, I might add), and set up a local shop to call me the next day (today) to set up an appointment.

Long story short, it's a quick fix that would normally cost ~$110 (~$180 if it's at your house).  Thought I'd give it a whirl, so here it is.

Incidentally, my TV is an LN32A650A1F, 40" LCD TV.  It's from 2008, so no surprise it stopped working

IMPORTANT NOTE:
While I have worked on electronics in many different regards, I am by no means an expert, nor certified to do anything.  I only did this because the warranty on my TV is expired anyway, so whatever I do doesn't matter.  Thank you.

First and foremost, lay it down and take off the stand:

Step 1 - Ignore sticker saying "Non User Serviceable Parts".  Step 2 - Scoff at electrocution warning
I put the towel down to prevent scratches.

Make certain you get all the screws to remove the panel:

There's 6 here; two amongst the plugs, one by the side plugs, and 3 around the edges


Screws are located along the edge of the TV; 3 on each short end, 4 on the bottom, 1 on top edge


Top center; one screw along the edge, 1 upwards relative in image

Final screws on the side
The panel, once the screws are all loose, just pops off, the screws don't even need to be outside their "holders" completely

Fan above the circuit board is pretty dusty, is that fan 1?  We have to assume there are others.....
Fan before a brief visit from the vacuum.... bleh.

Yay clean now!  But the question remains, is it fan 1?

To figure out if this fan is indeed our fan 1, I put it to the test.  Turn on the TV while the back panel is off.  Is the error message there?  If not, stop the fan.  Is the message appearing?

Success!  This was indeed fan 1!  Since it is, we can put everything back together.  However, this is just a temporary fix; I'm still getting a replacement fan and will take the old one out to put in the new one once all is done.

Huzzah!  Re-assembled and no error message!
Hope this helps anyone who needs it and good luck!  Also, the fan part number is G6015S12B2 if you need one.
