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.

Alright, thanks for the tip. Looks like I will junk this.

Send it to me ;D

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.

Good advise

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.

Good luck.
Let me know if you have any questions.

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.
