Waveshare Jetracer Pro AI kit not booting

[tonmath13]

Hello Team,

I bought two Jetracer pro AI ki

I have followed the instruction mentioned in the wiki page and downloaded the lastest 4.5 package zip file and flashed in microSD card( 62GB, UHS1). However after the power up ( green LED is ON), the OLED display is always off and no signs of system boot. The hdmi cable connected to the display/monitor also says no signal. I have tried with another Jetracer kit, but the same issue. Please support to resolve this issue. Thanks!

Note- The CPU cooing fans turns ON as soon as power is connected.
