OT Dell LCD Monitor Repair
« on: November 21, 2007, 09:30:16 am »
Hello All,

Has anyone tried to repair a Dell LCD monitor?  I have one at work that has a power issue that is internal.  I am wondering if it is worth it to try to fix it for my home arcade since the company is buying a new LCD.  Please drop me a line with any ideas.

I have successfully fixed a Dell E172FPB before. It had a few blown transisters.

Does the power LED flash a few times when powered on?

Funny, that is the exact same model I have.  And yes the power light just flashes on and off.  Is this something a nontechincal person can handle?

That's a tough question to answer. It requires completely disassembling the unit, unplugging pretty much all of the plugs and removing the circuit boards. I had to locate the problem, test the transisters, and then mod the board. The problem is a bad design by the manufacturer. What causes it to fail will do it again. The board gets too hot and the transisters fail over time. I decided to install a few mini 5v fans to blow over the board to ensure it stays cool.

So, the answer is clearly a no, a nontechnical person can't do it without learning a lot of skills to pull it off.

Don't give up just because one guy on a message board said it takes some technical skills... give it a shot, learn some stuff, have some fun.  Worst case is you learn a little and still junk it.  Nothing wrong with that.

Oh, I will still take it home this weekend and tinker with it.  I was trying to state that a repair he descriped is way beyond what I can and have time to do.  I love learning and trying though.  I did have fun in Electric Shop in highschool way back in the 80's and then Physics in college.  I'll give it a try and then we will go from there.

Well I took it apart.  After tinkering with for about an hour I tested it.  Now it is completely dead.  I broke one of the solder connections to a transistor with 4 pins and have to try to fix that.  I have a photo, but cannot remember how to post it.
