PBP suddenly wont turn on, first without SD card, now at all

[swulff]

Hi All

My PBP stopped powering on recently whenever the SD card was not in it with an OS to boot from. no reaction to power button at all, short press, long press or anything.

I took the back off, re-seated the eMMC card and tried again - no luck. checked all cables, no damage at all.

I tried the reset and recovery buttons - no reaction.

Now, I cannot power it on even with SD card in - both off and on charger.

Have anyone encountered something like this before ?

Thanks in advance.
