Alrighty,

Well first of all i appreciate you taking the time in reading this. I bought a Hp pavilion dv7 brand new from best buy couple months back. Ive never let a scratch on this. Only handled by 1 person. Never dropped nothing. Always on my office desk.

However, one day i turn on the laptop, and the whole color was faded in a very dull grey color.

I dont understand what happened.

my friend told me its the inverter that needs to be replaced.

Suggestions?

For : the washed-out, grey image on a nearly new HP Pavilion dv7 can come from software, a display assembly problem (panel, cable or backlight), or the video subsystem on the motherboard. ’s comment about hardware failures in some dv7 units and the warranty suggestions from and are useful, but a few quick checks will narrow the cause and make a warranty claim go smoothly.

Run these diagnostics before taking it back:

  • Connect an external monitor (VGA/HDMI). If the external image is normal, the laptop’s screen assembly or its cable/connector is likely at fault.
  • Reboot and watch the manufacturer logo / BIOS text. If the greyness is present before Windows loads, the problem is hardware; if only in Windows, think drivers or color/profile settings.
  • Boot into Safe Mode (or a Linux live USB). A normal image in Safe Mode points to driver or color-management problems.
  • Photograph the screen (and a short video) showing the issue—include shots during boot and in Windows. A dim-but-visible picture seen only with a bright flashlight usually implicates backlight/inverter; a full-color but desaturated image suggests signal/GPU/channel issues.
  • Run the laptop’s built-in hardware diagnostics if available and note any error codes.

How to interpret results and next steps: external OK + BIOS bad = display assembly/cable. External also bad = GPU/motherboard. Safe Mode OK = driver/config. Collect purchase receipt, model and serial, and the test results (photos/video and any diagnostic codes). Do not open the case or attempt board repair while under warranty, and back up important data before sending the machine for service. Present the evidence to Best Buy or HP support and request assessment/repair under warranty.

If it was the inverter you wouldn't see anything on screen at all unless you used a strong light on it. It being a HP dv series, it's far more likely that your graphics chip is beginning to fail as this is extremely common with that particular range of laptops. Indeed, it is by far and away THE most common failure with dv laptops. It's the result of poor manufacturing quality along with woefully inadequate cooling (to save money on production costs).
If it is still under warranty then take it back and get it fixed as it usually means a replacement motherboard is needed and that ain't cheap.

As the laptop is only a few months old, you can have it fixed free.

Go to Best buy and have them send it to HP for you.

I believe you still have warranty, take it back and solve it, is free.
