Graphics controller not functional

[thenunbus]

ok, ive just tried this but doesnt seem to effect anything i still get the blank screen and the same blinking lights. Ive also tried removing the memory, if i remove both sticks i get 3 blinking lights instead of 4 which means theres no memory which is correct so i reinsert my memory and im back upto 4 blinking lights Graphics controller not functional again

Again I appreciate your help, thanks

as erico says "

is actual way to fix your laptop..

other thing you can do one more experimentwith your laptop ..turn on and  cover your laptop base with a napkin/towel ball the sides .. let it opower on  for 2-3 hours.. it will heat .. then turn of and on again..

sometimes this "trick" work when your laptops graphic chip has a dry solder connection .. anyone who is facing this kinda display problem or beep problem can do this experiment..

THIS IS NOT PERFECT or ACTUAL SOLUTION of your problem.. this is JUST A TEMPERORY SOLUTION .. you can backup your data..

GOOD LUCK

You have 1 of 2 possible issues or both.  

I have found that the design of the DV4 video cable causes the pinching of the cable just behind the left hing.  This causes a short in the video cable.  This is HP part number 486878-001 which fits most of the DV4 models.   This cable includes the video camera connection. Please check to ensure this fits and is the correct cable for your DV4.  I have found 3 Pavilion DV4 laptops with this issue and the cost of this cable is as low as $7.00

The second possible issue is it truly the system board.  If you have replaced the cable and still get the blink code of 4, then you will need to replace the system board.  You can Google the full model of your Pavilion to find the proper HP part number.  Example: HP Pavilion DV4 1435 DX system board.  This model can be found on a white label under your laptop.  This cost is from $99 to $140

I strongly recommend you have a professional replace both cable and board as if you do not understand how to disassemble and reassemble you can cause more damage than good. 

The cable should take about 45 minutes to replace and the system board about 1.5 hours  if they know what they are doing.

Good Luck

Thank you very much. I had the same problem but your suggestion worked. The power reset! Never would have guessed if not for your help. Yes I had 4 blinks on the caps lock button and no display on the monitor. Now it works.

That suggestion is inherent with risk. If you try the "experiment" ,then you accept the risk of damaging the motherboard. If you do try this, be sure and remove the hard disk first to avoid other issues and protect your data.

Help please!! I have an HP Pavillion dv7. It was perfectly fine when I used it Monday night. Closed the top when I went to bed, woke up Tuesday and I am being a black screen and blinking lights. 4 blinks from the caps lock like everyone else that posted here. I REALLY need my photos off that computer - my wedding pictures are on there! Please help!
