Having problems with your Dell Inspiron 6400 Notebook ?

Replaced LCD Inverter, now screen comes on and bright but choppy

\015 I have a Dell Inspiron 6400. The screen went blank. I hooked it up to an external monitor and a diagnostics test, claiming that the LCD inverter was bad. I replaced the LCD inverter, and the screen came on just fine, no problems. But after being on for a while, the screen started shaking and different colored lines strewn across the screen. Its all jumbled up. Now, it will only turn on every once in a while, work fine for a few minutes, get all screwey and then go black. Is the new LCD Inverter bad? or is something else the problem now?\015

Answers :

Does the external monitor display a normal image?
\015\012If the images is OK then the video card is OK.
\015\012The inverter supplies high voltage to the CCFL lamp which provides the backlighing and does not jumble the colors on the screen. If you get a pinkish hue or a flashing screen then this would indicate
\015\012the CCFL lamp is faulty.
\015\012From the description of the fault, it indicates that the fault could be a faulty video cable or video connector. Try reseating the video cable/connector on the motherboard.
