När man startar den så visar den en Samsung-logga på displayen (har grafisk touch-display), och det är allt, kommer aldrig längre än så.
Skrivaren i sig fungerar, den är nätverksansluten och det går fint att skriva ut med den. Men kan inte scanna/kopiera utan displayen.
Googlade lite och hittade fler som verkade ha samma problem inkl. ett par "håll in dessa knappar när du startar"-förslag, men inget som hjälpte.
I och med att den fungerar i övrigt antog jag att det är display-delen som strular och skruvade isär den, hittade ett kort med en Texas ARM-MPU, DDR-minne mm.
Hittade en enda liten elektrolyt, men inte mer än så som spontant brukar "slitas". Mätte kapacitansen på den och verkar OK, inte mätt ESR men tror inte den är problemet.
Såg ett kontaktdon märkt "DEBUG", intressant.
Mätte på de olika pinnarna och minsann, en av dem såg ut som UART på oscilloskopet, och bitlängden stämde med 115200 baud. Kopplade in till en USB->UART omvandlare till datorn och mycket riktigt, det är konsol från ett Linux som körs på displaykortet.
Nu visar sig också att det är här problemet ligger, Linuxet kraschar under uppstart.
Här är full utskrift från ett uppstartsförsök:

Den säger ju också "UBIFS: recovery needed, UBIFS: recovery completed".
Hittade även vilken UART-RX på kortet, och lyckas stoppa den i U-boot och har full access där.
Funderar på om man kan hitta på någonting där igenom för att rädda flashminnet.
"nand bad" returnerar underligt nog inga bad-blocks, kunde man kanske förväntat sig om det är så att minnet är sönderskrivet.
Någon som har några idéer kring vad man kan tänkas hitta på?
