I have a HP Pavilion dv4-1220us Laptop and the screen flickers at the bottom. A 1/8" white line will appear at the bottom of the screen-this happens after about 1/2 hour of starting it up. Later the whole screen flickers as if a bad reception--it does this even if not hooked up to the net or power.

hi
I had the same problem faced twice in one month, and it’s a new laptop just one month old,
I have removed battery for for few minutes and fixed it back. And it's working fine now.
If it continues what should I do?

Yes, this is a defective screen. The only fix is to replace the screen. It's called a column of dead pixels. Since it is under warranty, contact HP to have them warranty it out or take it back to the place you purchased it from for an exchange. Please take a moment and give this answer a good rating of fixya. Thank you.

Is the computer new? If it is, send it back to where it came from for a repair.

If it is not new and it has passed its warranty, then you may have to take the Basel of the screen and see if there are any sockets that are not connected properly. The problem with doing this, with SOME laptops, you have to take off the main cover off the laptop before you can take the Basel off the screen.

If you do need to take it apart, please touch something like a metal plug sockets screw or a unpainted radiator pip before you do this to get rid of any static you gave on you otherwise the is a chance of permanently damaging you computer

the connections inside laptops are usually just thin wires that go into sockets and the clips that secure the cables lift up and the cable can just be pulled out or inserted with ease. If you can open your laptop and check the connections, just firmly push them all in to make sure they are all connected properly

Good Luck

This is caused by burn out of the Nvidia graphics chip on the motherboard. You need a new motherboard. This is due to a design flaw (the subject of a class action against HP in the USA). I have had two motherboards fail on me in this way so far - do not expect any worthwhile support from the HP "support" people they are all in India and can hardly communicate outside of their simple repetative scripts. Its impossible to escape them - I tried communicating with head office but all you get is contact details back to the incomprehensible Indian call centre. I strongly recommend against ever purchasing from HP again.
