Help needed please!!Asus X55A-SX119H display problem

[Giff1711]

Hi there, need a little help
I have a Asus X55A-SX119H with the B830 cpu. https://www.asus.com/Notebooks/X55A/specifications/
When i power it on it shows the asus logo then goes blank, the back lights are working you can see the screen lit up, the hard drive light comes on for about 30 secs & the cd works. But i am unable to access bios or any boot menu, if i attach a external monitor i get a total blank screen not even the logo. I was thinking it could be the bios but the battery charging led works & hd led & cd spins. If its not the bios could it be a graphics issue on the processor side has this cpu has intel hd integrated graphics. Its just weird how it shows the logo then goes blank every other graphics issue i've had its blank the second you power on ?
Any help would be much appreciated, I have attached a video so you can see the problem
Thank you

Hi Giff1711

Have you tried starting it without the extras... Like take out the HDD and the CD Drive. Esp the HDD...

Oh and also try it with out the KB if you can...

Also when you tried it on the external monitor did you do it via old VGA analog or HDMI? Sometimes when you have dedicated cards you'd get something on the analog side and not the HDMI... But i don't think that's the case here as that CPU has Intel® HD Graphics embedded.
