Asus F555LD - No display, Blinking Airplane mode light

Hello everyone,

I'm having issues with Asus F555LD laptop.

The laptop won't display anything, the cooler is spinning and the power and battery light are on constantly but the airplane mode light flashes.

Tried to:

Reset CMOS - i tried holding the power button for 40 - 60 sec, first variation without adapter plugged in, 2nd with adapter plugged in.

Cleaned from dust, changed thermal paste, removed everything from the board - still nothing

BIOS recovery with usb - did not help as well.

- Laptop history : The laptop had swollen battery so i had to remove the battery, it works while on charger constantly without an issue, it has 4gb ram soldered on board.

Tomorrow i'll get a new battery and check if that is causing the issue.

Has someone had issue like this?

I couldn't find any reference to blinking airplane mode light, while the Power and Battery light are constantly on.

Thanks for any answers in advance.
