Thanks for the reply.The system is out of warranty. Before I go and replace the backlight, I just want to be 100 percent sure thats the problem. Can anyone else confirm this? Also, how much would it cost me approx.? Thanks again
PS. I am computer literate, will I be able to replace the inverter myself?
The backlight is failing. If the system is under warranty, call Dell and have them replace the screen. If it's out of warranty, contact an LCD repair shop and have the backlight replaced.
If the external display works fine, the problem is either the bulb or the power supply for it (the inverter). You can have the bulb replaced and/or the inverter rebuilt for $100-150 or so.
Replacing the bulb is the more difficult operation, and the more likely to be needed. While replacing the inverter is easy, it's less likely to be the problem, and finding the part is much harder (the inverters, unlike the bulbs, are not sold separately from the display panels, so having the existing one repaired, if it's faulty, is a much simpler option).
I found an inverter on eBay for $25 dollars. I think I will try replacing it and if that doesnt help, i will take it in for repair. Being a broke student is not fun :( . Is there a guide for inverter replacement? Thanks
Not as such. You'll ahve to remove the display panel. The inverter is behind it (follow the wire up from the mainboard).
It is very unlikely the inverter is faulty. Replace the bulb first; it'll save you from throwing away $25.00. Also note that the inverter is exact-model screen specific (i.e., if it's for a Hitachi screen on an 8200, and you have a Sharp screen, it won't work), so check your make and model before you bid on the inverter.
