Raspberry Pi 4 not responding. Only shows RED light. No green light

bugtech
bugtech over 1 year ago

Hi. 

I was working on my newly bought Raspberry pi 4. Suddenly after shutting it down to remove the camera cable, It is not responsive anymore. I have read various posts regarding this issue but no help. 

I have tried 3 different SD cards but still its not responding. What can be the issue? or how can i fix this? 

Thank you

    What are you using for a power supply?

    How did you perform a shutdown? Pull the wall wart, pull the power connector on the Pi, issued a shutdown command.

    How did you remove power. Pull the wall wart or pull the power connector on the Pi?

    Confirm when you modified the hardware configuration of the PI (i.e. removed camera) it was done with the power off?

    not even a blink of green led? Different patterns of blinking (long and short) means different boot errors...

    There is no sign of Green light. I think the board is fried.

    have you examined the camera socket? maybe something has happened during cable disconnecting (eg faulty socket introducing short circuit when no cable)... maybe reconnecting the camera (or cable only) may change something if the last operation was cable disconnection (or the camera may be fried by the damaged rpi - so the cable only could be safer)

    or even maybe there was some custom camera configuration done that is preventing booting without it? Considering that (IRRC) in RPI the GPU starts the board, maybe it wants the camera back to proceed with booting? but is's only a wild guess...
