Laptop won't start on single press of power button

[patelrishi621]

i have a TUF Gaming F15 FX506LH.
Its more than 1 year old and out of warranty but recently got a new problem that when trying to boot if i press power button the power button led lights up and power indicator led also lights  up along with keyboard backlight but it does not post not storage led light up  and eventually sometimes shut down itself and sometimes get struck on backlit keyboard and nothing on display so i have to shut it down again using power button and it takes 5 to 10 times to boot up.

Is there some way to troubleshoot this without taking in service center because i need it regularly.

Please test with an external monitor. 
If the external monitor displays properly, it indicates a fault with the laptop's own screen.
If the external monitor also doesn't display anything, it could be a problem with the motherboard components.
In either case, it is recommended to take the laptop to a repair center for further evaluation.
