|Hi, I have very strange behaviour with my laptop screen.|
It shows green pixelated lines allover the images especially black..The pattern is strange and looks like as if a plastic sheet is being pressed on the LCD, This is the issue right from the moment the laptop starts up HP LOGO, BIOS, etc...not specific to OS. everything black is shown as almost green.
This distortion is sometimes intermittent and all of a sudden the screen comes back to normal all by itself.
All this while I have a external VGA monitor attached and it works perfectly fine.
I have replaced the entire display unit(lcd, cables, etc..) for the laptop, it worked fine for a week and the exact same issue is back on the new LCD as well. Still my external VGA has no issues and is perfect.
I have noticed one more strange thing happening with LCD...when I start to play a game, about 5 mins into the game, the LCD becomes normal again and stays perfect as long as I play the game.
I have no idea what is happening and how to isolate the issue. I am trying to break my head to isalate but cannot say if it is the Graphics card, Video RAM, bad interface or some loose connection.
All I know at this stage is it cannot be graphics card as external monitor works fine and also not LCD as the new LCD also showing same pattern as old one.
Please help if anyone can...sorry for the long post.
