    Exclamation LCD has red background .. very disturbing.!

    Hi,
    I'm using ubuntu 10.04 on a Dell inspiron 1420 laptop which i purchased 3 years back.. usually while starting the dell logo appears on a black background,but suddenly 2day morning it has changed to a bright red background.. it causes a blurred visuall effect on the screen and all colors appears changed...
    Is this a hardware problem or software problem??while running diagnostics the colors were displayed but still i could do nothing to change it...
    Plz help me out with this....

    sounds like LCD screen died. i had this happen to one of my laptops once, and replaced the screen. it works normally now. but, that laptop was a pentium 3, so it was a little old...

    i replaced mine myself. it wasn't hard. (but ive been working with computer hardware a while...) the challenge is finding a screen that is exactly like your current one. they usually run around $20 on ebay. (but i haven't checked prices in a while, and it varies by brand, model, etc)

    if you want to replace it yourself, just make sure you are careful and put everything back exactly how it was. chances are there is a how-to out there somewhere, and if you cant find one, the manual for your laptop should help.

    could you clarify a little more?


    another question... what tests did they run?

    does the POST screen have a red color?

    Re: LCD has red background .. very disturbing.!

    ->Usually during startup i have this dell logo with a black background,but now a dark red background is coming this red shows up even on my desktop, this also causes most of colors to change.i.e white is not shown as light sky blue and etc ..... the contrast seems to be more...


    ->The test is D+power button to test the LCD(on DELL inspiron 1420),it displayed different colours with absolutely no problem,there was no distortion in those colors....


    ->I didn't get the POST thing... i'm assuming it to be my desktop,yea the problem is that the red background is there but not everything is red(some areas have red horizontal stripes ) ,this red bacground causes other colors to look different.. i can adjust brightness and all.....!!

    What could this problem be... kindly assist... i read somewhere that LCD's are robust and doesn't need replacement unless physically damaged or cracked...!!!
