work pi 4 not

Pi 4 not work :(
#1
Buonasera, richiesti consigli per trovare causa non funzionamento Pi4

Cronologia:

In possesso da poco meno di un anno, piano piano preso confidenza con il dispositivo.

Ho provato a installare Manjaro su sd, ma purtroppo sono iniziati i problemi.

Non rilevava più nè tastiera nè mouse.
Preciso che adopero alimentatore, tastiera originale, mouse amazon

Effettuate ripetute installazioni di Raspberry O.S., ma il problema persisteva.

Allora tentata nuova installazione della eeprom da sd, come indicato su:

https://turbolab.it/bios-501/guida-raspb...oader-3072

e successivamente su sd 32 Gb nuova di zecca con Imager installato O.s. Raspberry.

Purtroppo attualmente l'unico sistema per comunicare con il Pi4 è in ssh attraverso un altro pc nella stessa rete. Non si visualizza neppure lo schermo, e vnc non visualizza il desktop, sempre da altro pc

Di seguito il risultato del comando dmesg

Codice:

A questo punto non saprei che pesci prendere, considerata anche e sopratutto la mia scarsa capacità....

Come anzidetto, risulta inutilizzabile.

Può essere un guasto oppure trattasi di altro motivo?

Grazie anticipate per eventuali indicazioni.

potrebbe essere un guasto alle USB. hai provato altri dispositivi USB? Chiavette o altro se vengono viste correttamente?

Si Zzed, provata altra tastiera e altro mouse. Senza risultato.

La garanzia legale (quella che ti dà il venditore) è di due anni. Contattalo e spiegagli il problema, potrebbe essersi guastato.

Attendo se qualche utente mi fornisce qualche altra indicazione, poi contatto come hai detto Melopero. 
Spero di risolvere

Se non vanno le porte usb e il monitor, rispediscila di corsa al venditore.
se hai una lampadina usb, puoi attaccarla per vedere se almeno gli arriva corrente.

Ho inviato una mail a Melopero chiedendo info sulla procedura di garanzia. 
Speriamo venga riconosciuta la problematica. 
Grazie
