WC 7855 stuck at energy star screen with code 5 on the pwb

[Geertjen]

Hi,

My 7855 is stuck on energy star screen with code 5 on the lcd. I’ve tried Altboot with usb on front and back, but nothing happens (usb maybe disabled?)..

What could be the cause and what would be the solution?

Regards

Hi,

It could be a defective SD card or even the SBC PWB. If you have another known working WC7855 you can try to clone the image of the SD card, otherwise you must buy a new SD card ( part no. 237E27210).

Replacing the SD card with a new image and then altboot did the trick. millions thanks
