[Monitor] Samsung Syncmaster 930b Problems

Hi guys,
I'm having trouble with my Monitor.
First off, starting maybe a few weeks ago, the screen would start out dark.
Maybe 50% darker than normal and make a weird buzzing sound.
Recently, it's almost completely dark(98%) I know the desktop is coming up because I can see it if I look close enough.

It comes back to full brightness usually within 30 mins.
Now I have a few questions.
I'm assuming this is probably my backlight that's busted and needs to be replaced.
Although, I have read a few people say that sometimes it's the inverter(?) that might be the problem. How would I know specifically what the problem is?
Second, I'm looking for a place to buy a backlight from, but really have no clue where to start looking for a reputable place that might sell them, or what type I need. Also, while I have some general electronic know-how. I was wondering if there was any general guide on how to do this?
Also, if there's any more information that you need, just let me know.

Thanks in advance

Can't find a disassembly guide but there is this thread full of info about similar issues resulting from bad capacitors;

Sorry for the late reply.
Thanks for the reply though. I'll take a look at that link.
bump to see if anyone can answer the other questions.
Reputable place that sells backlights.
