HP 15-N096EA Display :: Screen Colours Inverted Also Flickers Back To Normal

Model: HP15-N096EA ... When the laptop is turned on the screen colurs are inverted i.e. blue becomes orange, white becomes black etc. at times it flickers back to normal colours i.e blue shows as blue etc.
 
I have checked magnifers invert colours isn't turned on but when I do turn it on the inverted colours switch to normal colours obviously. There is also a vertical shimmer like every other vertical line is missing or phases in and out.
 
I have booted into safe mode to see if its a driver issue but the colours are still inverted, I've booted into the BIOS and again the colours are inverted and just to cover all bases I booted a live DVD of Mint Linux 17.1 and the legendary green of the mint distro was a lovely lilac. I've also tried high contrast i.e. Left ALt + left Shift + Print Screen.
 
My feeling is its the graphic chip or the monitor and I'm hedging more towards the monitor. Tomorrow I'll do a screengrab to see how that comes out and will also connect to an external monitor to see if the flicker and shimmer is still present.
 
Considering this is literally a month and 6 days out of guarantee it pretty bad, I would have expected a bit longer from a laptop before it started failing. 
 
Update from Yesterday: I did a screengrab from the HP using the snipping tool in windows 7, this showed the colours inverted i.e. negative, I saved that screengrab to a USB stick and opened it up on my Mac, the image showed correctly i.e. not as a negative.
 
This is the image that is displayed on the laptop, there is no colour inversion, none of the graphics settings appear incorrectly set, I did actually set all settings back to defaults.

This is the screengrab from the laptop as it displays from another computer, which, in my case was my Mac. The screen appears to be displaying correctly, hence the screengrab image below but for some reason it is displaying an inverted image - Its like there is an overlay on the screen. 
 
Could the inverter be faulty?
