Sounds like you have a failing backlight. The flourescent tube at the bottom of the LCD that make the screen bright enough to see will change to a reddish tinge as it goes bad. Eventually the tube will not generate light at all and the screen will go black, but you can still see the image faintly if you use a flashlight at an angle to the LCD surface. You might also hear a faint buzzing sound, just like when an overhead flourescent goes bad.

Replacing the backlight is a tedious and difficult job. First the LCD panel has to be removed, and then it must be disassembled to get to the backlight. The tubes can be purchased on eBay but they are leaded glass and very thin, so they tend to break easily. There are two contact tips must be desoldered and then the two new ones soldered before the LCD panel can be reassembled and then put back into the upper half of laptop.

For a beginner, it is much easier to replace the entire panel with a new or known good used one. Best bet is to check your warranty first, otherwise a full LCD panel will cost at least $75 plus the labor to install.

As for the TV out, the preferred method is to hook an external by VGA cable to test the video card. You should get full picture with proper colors since the problem is in the laptop's display itself. The TV out jack requires drivers and a functioning XP to display.

Hi
I think the battery you bought is not compartible with your pc notebook that is why you are experiencing such problem.All you need to do is to get to the store or outlrt where you got the battery and get it replaced for a compartible battery or better still you should go along with your system.
GOODLUCK

Networking with LAN


The most laptop now comming with recovery software loaded on one of their disk partition (generally D: drive). So it will help you to get back all sofware and driver as it was issued by company.
So you can use this utility to get back your OS and drivers.

If this is not the case with you. then you should go the dell website, navigate the drivers and downloads section and enter your service tag no (not model no.) and then it will give you all the supported drivers for you laptop. Download as per your requirement. And install them.

Laptop goes dark


You can refer to this document for display assembly. It looks like the display is going bad. By checking the seating of the display cable, you're isolating the fact that the cable is connected.
