\015 I have a dell inspiron 6400 laptop and would like to no how to replace the lcd inverter on it?\015

Answers :

Use the number that is on the old inverter !

It is quite possible that more than one invert is used on the same model and until you have the number its not worth ordering.

Also you may find that it does not fix the issue as it can also be the BACKLIGHT too that is out.
These are best replaced by a local computer shop as they are very very fragile and easy to break being only a 1.5 mm or 2 mm thick flourecent tryp tube that connects to the inverter.

If I do an inverter I often do the backlight at the same time to save myself the hassle of opening it up to go again a short while later.

The prices for inverters are around $20 CDN and about the same or less for the backlight.
Unplug your laptop and remove the battery. To replace the inverter, you will need to remove the rubber tabs along the sides of your lcd to expose the screws. Once you have unscrewed the screws you will then need to pop the front of the lcd cover off. This is usually very easy to do but sometimes you have to take a small screwdriver and wedge it loose. the inverter is a long thin pcb that can be found underneath the lcd or to the right of it. It usually has to wires leading into it from the motherboard and two wires leading out of it to the lcd. unplug both ends and if it is screwed in, remove the screw. Then simply put the new inverter in and reverse instructions for reassembly.
