Monitor dim and burn smell

[thedarkmist]

Hello,
I own a dual monitor set with 2 different samsung monitors. Today I disconnected one while the computer was on (and the other monitor as well) and after about an hour I came back and plugged again the monitor. I discovered that the monitor that was remained on (a Samsung Syncmaster T240) was smelling like plastic burn or something. Now, I can see that the monitor is dimmer that normal. Not black, but it seems the brightness is set to, let say, 60% while it's still to 100%.
Can the detouch and reattach of the secondary monitor have cause the damage? Should I investigate for a bad cap or this kind of problem cannot be related to that?
Kind regards.

Welcome to the forum-

I would suggest that you start a new thread for each faulty monitor you want to check in the
"Troubleshooting computer displays" forum

We can help a lot more if you please post good clear pictures of the whole chassis, and then pictures of each board, front and back and close up of connectors, (max resolution 2000x2000 and 2MB) using the manage attachments button, which is found by clicking "go advanced" under quick reply.

Please do not post inline and offsite as they slow down the loading of pages.

It will be useful if you can say what happens from when you plug in switch on Sounds smells and what the power led does up to the point where the problem is.
Also say a bit about yourself - skills tools etc. there is no point in starting if you dont have a multimeter and soldering equipment

It is unlikely that unplugging one monitor and reconnecting would cause the problem
unless you have pulled very hard on the wires on the T240.

Re: Monitor dim and burn smell

Thank you for your reply!
If you can, please move this thread to the right forum, so I don't have to duplicate the thread. Can you?
In the next hours I'm going to open the monitor and take the pictures.
The monitor seems work normally except for the smell (now less strong) and for the less bright image.
I have basic skills. I replaced some capacitors on another monitor, and I have solder, multimeter and other basic equipments, but I'm new to practical electonics (I studied it at school, but it was 15 years ago and my job is in the software field )
Should I have care about not touching the big power capacitor to avoid shocks? Or does it discharges itself when the monitor powers off? Shoul I use plastic gloves?
Thank you!

I cant move it - Just start a new one in the monitor forum and cut and paste your post into it.
