I recently got a Raspberry Pi 4B and i used a 128GB MicroSD card and copied over the files from Noobs 3.2.1. I connected the MicroHDMI > HDMI to my TV and connected the power adapter and turned it on. My TV (multiple TVs tested, Samsung and Toshiba) doesn't see the Pi, and says "No Source Found".
I can see the Rasp Pi has a steady red LED on and the green LED is blinking 4 times and pauses and blinks again and continues this step.
Please help me resolve the issue. If any other information I need to provide, let me know.
P.s. I don't even see the rainbow screen, the TV just doesn't see the Pi at all.
