Default Transformer power button would just blink twice

Could someone help? Bought a second hand prime and thought to have the nearby Asus service center fix its touchscreen digitizer and camera. They said that it would cost too much to have it fixed because the "mainboard got damaged".

The device was working fine before but I thought they meant that they couldn't repair just the touchscreen because of the mainboard mismatch causing the inverted X axis so I thought to claim it and cancel the repair and just use it as an Android laptop.

When I bring it home to charge, now the tablet would not power on and would only show me 2 blinking orange lights when plugged in (to the keyboard or the wall charger ). The charger would charge the keyboard just fine (it's at green) but plugging the tablet into anything would just show me 2 blinking lights then nothing.
