I had an LCD monitor that started developing a brownish discoloration at a corner, and I'm not sure if it was the pixels or backlighting. Then, over the course of a few weeks, the discoloration slowly spread and the monitor would make strange static noises while making a slight flicker. Finally, one day the monitor completely blacked out. I tried external solutions such as swapping cords and plugging it into the other DVI slot to no avail, so it's definitely an internal part failure. Currently running on a different LCD monitor as I type this.

What are my options in terms of repair? I'm relatively tech savvy so I would be willing to DIY a fix(backlight replacement or backlight inverter perhaps?). If not, about how much would it cost to get this fixed?
If it helps, the monitor was an Alienware AW2310, and I've never heard of any fail like mine.

I don't find a clear statement online as to what backlighting this model uses, but either way, the description sounds almost certain to be a backlight fault. If it is in the backlights themselves, normally this is terminal, as panel replacement cost is prohibitive. If someone is prepared to dismantle the panel and look at sourcing and replacing lamps/LEDs, it could be feasible. If the fault is in an inverter/LED driver, they are usually part of a PSU PCB, and since component level repair is usually unfeasible, board replacement is the norm. I have no experience of parts supply and cost for the brand.
