Apparently broken 24" LG --- Any ideas on trying to fix it?

post #1 of 42
Thread Starter 

I believe that may be my monitor^^ I bought it used over 4 years ago. It has been a GREAT monitor and I was so pissed off the other day when it suddenly stopped working.

First thing I noticed was once I had to press the power button like 5 times and the LG screen kept flickering on and off. Then it went on and worked and I thought it was just some kind of glitch. That night I turned the monitor off and the next day when I went to turn it on it just refused to turn on. Every once in a while the blue light underneath would flicker on for a second and I might see the "life's good" logo for a second but then it would quickly turn back off.

I tried it on another desktop with VGA instead of DVI just in case. And no luck. I tried different cables and no luck. It is the monitor for sure.

Since it is rather old and large and has vents I thought maybe it has over heated and I sprayed it with compressed air to possibly remove dust. I was also thinking of opening it up and trying to clean it... but I want to see if anyone has any ideas and stuff? I don't know a whole lot about how this thing functions but if something on the inside burnt out maybe I could replace it?

Right now I am using a backup 19" and have a decent 23" dell otw. But if I could get this back up and running then I would be so happy. I want to at least try before I chuck it.

+1 You really don't have anything to lose if you pop it open and check the caps, since it isn't working anyways.

All good suggestions. I will only attempt the cap replacement if they are obviously 'bloated' though because I am not supremely confident in my abilities.

I'll open her up tomorrow.

Curse you guys... I wanted the glory of posting the Monitor Recap tut.

Back on track. Replacing caps really isn't hard. If you have some soldering skills you should be able to handle it with ease. My advice thought is to find a desoldering tool or get proficient with solder braid.

Maybe the back light is dieing?

Check the backlight. It's likely a power supply issue, likely capacitors. They have a finite lifespan, though other parts can fail.

You can replace a cap without a soldering iron.I fixed a dell panel this way.Take it apart,separate the PCB and bake it.When it's hot enough you can remove the cap and insert new one.
just make sure you dont have the board upside down,or all the little parts will fall when the solder melts.Don't ask me how I know.
