I don't know if the truobles listed in the post subject all come from
a processor failure, anyway the problems persist.
Sometime the startup is immediate, several consecutive times, then it happens
the boot hangs at beginning, with a white display ...

Any suggestions?
I've opened and observed the unit at scope, re-done the soldering of the processor,
but nothing changes.

Thanks
