My Pavilion dv4-1225dx is not showing anything on the screen also when i connect my desktop screen to in i get nothing on the screen. The caps lock and scroll lock light blink 4 times i looked it up and it appears that it is a sign of Graphics controller not functioning. If anyone has any suggestion on how i can fix this i would greatly appreciate it.

If it was a desktop model you could have a new graphics card fitted, but with a laptop that's not an option. You need to have it looked at by a computer repair shop as it's possible the graphics controller is faulty - it's not a DIY job.

Laptop would have to be taken apart. video chip would have to be unsoldered from the mainboard and a new chip soldered on. On misplaced drop of solder and the board is fried.
Next problem is even trying to find a new video chip for the board itself.
Have you tried a external monitor to make sure it is the graphics chip or is it a screen problem?

Bad video then. You would have to contact the manufacturer of the laptop and see if they can sell you a new video chip. Not sure on the cost though as it is something most computer shops won't do it. They would just replace the whole motherboard or advise you to buy a new laptop.
