Screen Replacement part L05N

I was busy drawing in mspaint when screen made a strange sound and line appeared on screen that resembled the same lines that you get when a gprs modem is to close to the screen and then promptly died on me with a small cloud of gray/black smoke rising from the monitor, I opened the monitor seeing as the warranty has expired a long time ago, I looked around to see if I can find what blew, I came across a ting that looks like a capacitor that has melted down almost completely, I need to replace that specific part, as no other components were physical damaged at all (from what I could see) the number on the part (that was barely visible after it melted) is L05N, the number on the PCB above the part is L703, it is situated in the following grid number : C2 (according to the numbering on the PCB) the modal number of the screen is CB775BN and the serial number of this specific screen is 006KM04643 manufacture date June 2000, where can I order or get this part in South Africa?

My problem is that with this monitor I have noticed that there is a red line that moves up and down the screen - in a random manner. I thought that the line only showed in the background but it also...

With this I would normally tell you that you have a dead pixel and you need to return the monitor to the supplier. But it is very strange that the line moves.

Monitor screen is perfect , but there is one 1mm lightgreen color line appear verticallly in the screen...

It would appear that the monitor is going bad. If it is within a year of purchase, contact dell for a warranty replacement. If not, use it until it dies. It depends, but usually bad pixels and lines like this will spread rather quickly.

Thin yellow line on the right of the LCD Screen

all those sounding intelligent and saying that replacing lcd hardware will fix the problem probably didnt have the problem themseleves . i had exactly same problem with samsung syncmaster 2043swx monitor . i just restarted and booted into safe mode ( by pressing F8 key at startup ) tried changing reolution in display settings . rebooted in normal mode and asll lines are gone and never appear again . i am uisng windows Vista . so i think it is probably a driver glitch something .

A follow-up on my Dell vertical lines issues

I understand that it seems odd that sometimes they disappear.
I have a vertical line on one of my laptops right now that it takes about 3 seconds before it appears on the screen but once it's there. It's there.

I think it has to "warm up" before it comes back.
I used to do Technical support for a company that produced computers with 5inch wide screens, and everytime something with a line was mentioned, "Fix display cable" was the reason.
Because everytime you pushed the screen up to see the keyboard the line disappeared (because the display cable moved) But I digress.
All I'm certain of is that if you change the display cable this will be fixed.
