emmc mode Boot Up issue

[Safepro 0]

Hi,

I am new to Tinker board. Right now i am using Tinker board S R2.0 model.  I am facing issue in booting up the system. After flashing(using balenaEtcher) the OS(Tinker_Board-Debian-Buster-v3.0.11-20211026) into the eMMC storage successfully , i have connected the board to the monitor, keyboad ,mouse and the power supply(5V/3A micro USB). But the red LED light doesnot glow, even if it does, it blinks but doesnot glow continuosly. So i decided to give the power supply from the CPU and it works. But again an other issue arises. The boards switches on and i can only see the image(font) of the Tinker board but after that nothing shows up.  I have attached the image which i can see after powering the board. So please help me out in resolving this issue. Let me know is there anything else that i have missed.
