Question What is wrong with my Raspberry Pi Compute Module 4 + IO Board?

[Dark Sorrow]

As the title suggest, what is wrong with my Raspberry Pi Compute Module 4 + IO Board?

System Specifications

1. CM4108032 (8 G.B. RAM, 32 G.B. Storage eMMC, Wi-Fi)
2. Compute Module 4 IO Board
3. 12 VDC, 3A Power Supply
4. 1 Gbps connectivity to Wi-Fi Router

Once I power on my Raspberry Pi Compute Module 4 + IO Board using 12VDC power supply via J19 Connector (Barrel Connector), all 4 LEDS continuously glow

1. Red LED
2. Green LED
3. Both LEDs on Ethernet Connector

I though their was some hardware damage but when I disable eMMC Boot and try to flash a new image in the board using Raspberry Pi Imager; I'm able to flash the new image.
However when I try to boot from eMMC I get the error.

Even if I connect the network cable, the network device is not detected and the system/device is unresponsive. I'm unable to get SSH access.

This is the second Raspberry Pi Compute Module 4 + IO Board facing the same problem.

Could this be due to high humidity (their are thunderstorms where I live)? Is this board damage? Can someone enlighten me.

Was the same imager used for both Raspberry Pi's?

Did you try another card?

Yes, the same imager used for both Raspberry Pi.

Other Raspberry Pi Compute Module 4 work properly.

Doublecheck the documentation, installation, configuration, and testing.

Change things around but make only one change at a time.

Objective being to eliminate possible culprits.

If everything works except for the Raspberry Pi in question then the Raspberry Pi is likely defective.

Return for refund or replacement.
