Have you checked the entries for your machine on ebay? I recently replaced my inspiron 7500 lcd for under $50 bucks. If you are handy or have a handy close by ;) ;) replacing the screen is a moderate to difficult task. First test to see if your lcd is bust - or the PC. Plug in a CRT monitor as the alternate screen to see if you get the usual boot etc. Once you know that the PC responds fine, the next step is to check if the inverter board or the rectangular LCD itself is bad. In my case I thought is was the board...but turns out it was the LCD. Check online for how-to details of LCD replacement to help you zero in on the problem. Big Important!! Be sure you remove the battery and the laptop is unplugged before you take it apart..this doolie can really give a jolt if you aren't careful. Fixing involves a small phillips driver and maybe a small flat blade for gentle prying of the LCD. The inverter is usually a small candybar/bookmark sized card at the base of the screen. Most laptops have a bunch of screws holding the screen together w rubber or plastic dressage covers to hide the screw heads. both the inverter and the LCD just plugin via jackcords to the laptop..
Okay, on the off-chance you get away with just replacing the inverter you are looking at about $10 or so for the card...the LCD off ebay will maybe run as high as $60 as a rough guess(depends on make). inverters have 2-3 small screws holding it in place so it doesn't move and the jack is about a 1/2 inch wide and plugs only one possible way(like your 3-pin wall outlet plugs). Tricky bit is the LCD as I discovered w my inspiron...they had several versions of the hardware so use the code of the LCD(from ITS product panel) when you search for a compatible screen NOT the laptop series/model #...the LCD is a fitting problem if you get the wrong LCD as there are a doz of so sm screws that hold it to the bracket. The bracket usually comes apart as 2 front and back pieces...as you go note down what screws/etc went where so you can get it all together again. So if you keep the parts all straight as to location just put the new in place and put it all back the way it was. That is basicly it. So, its not rocket science but more than a simple unhook and plugin job.
I aint no tech but my fokes are... (the kid is typing not the user) but even if you do find a repacement screen for extreme cheep price, it is risky to change... aparently many technicans refuse to touch a laptop screen because of its complexity and will reply get a new laptop. But yes it will be double the cost of a new laptop, this includes TV's (LCD, DLP, PLASMA and etc...).
sorry for the FYI cuz i am just warning consumers oh recomendation buy extended warenty it does come in handy..
