Xerox 700 Not Booting After Water Damage 每 MCU Board Tested
Xerox 700 Not Booting After Water Damage 每 MCU Board Tested
Hello colleagues,
I*m working on a Xerox 700 that suffered water damage. I*ve already completed a thorough inspection and testing of the power supply unit and the MCU PWB board (960K47402K001). No visible component damage or burn marks were found, and multimeter tests show continuity and stable voltage across key points.
The board receives power and shows electrical pulse activity. On the control panel, three LED indicators flicker, but the machine does not boot or initialize. No fault codes are displayed, and the screen remains blank.
I*ve also checked:
Multimeter continuity between P425 and P404 (signal path confirmed)
EEPROM chip presence and response (planning to test with EECLIP programmer)
No signs of short circuits or overheating
Before I proceed with EEPROM firmware recovery, I*d appreciate any insights:
Could this be a firmware lockup or corrupted EEPROM?
Are the flickering LEDs on the panel indicative of a specific fault state?
Has anyone successfully recovered a Xerox 700 board post-water damage?
Any guidance, firmware references, or diagnostic tips would be greatly appreciated.
Best regards, Stanley Mdakane

CHAPTER ONE "But what are we to do?" said Arthur, raising his voice. "Tell us what we must do to avoid following you?" CHAPTER LII. THE CAGE IS OPENED. Steam-engines. Nine chickens were killed by a weasel or a skunk or a rat last week. Some prisoners were brought to the train; a single sepoy led them by a chain. Two carried enormous bales, and the third a heavy case. They packed themselves into a compartment that was almost full already, and one of a couple that were chained together by the wrists put the chain round his neck; then, when he had scraped acquaintance with the other travellers, he amused himself by tormenting the hawkers of drink and pastry, bargaining with them for a long time and buying nothing, quite delighted when he had put them in a rage with him. Instead of the usual wreath of flowers for my neck the Rajah gave me a necklace of silver threads, to which hung a little bag of purple and green silk, closely embroidered, and looking like a scent-sachet, or a bag to hold some precious amulet. Il est sans c?ur et sans entrailles.§ [4] When they climbed above the lower shoreward mist the cry from Sandy drew their attention to the seaplane, even higher than they were, and going fast across the narrow end of the island. As they swung in a banked turn to circle over the Sound, the green disappeared and its place was taken, as it seemed, by red. Landor came trotting over from his quarters, followed by his orderly, and the troops moved off across the flat, toward the river. "Where are you goin'?" he said sternly. She could never guess what that child meant to Reuben. It meant a fellow labourer on his farm, a fellow fighter on Boarzell, and after he was dead a Man to carry on his work and his battle. At last he would have someone to share his ambition〞that child should be trained up in the atmosphere of enterprise; as other fathers taught their children to love and serve God, so Reuben would teach this son to love and serve Odiam. He would no longer strive alone, he would have a comrade, a soldier with him. And after this boy there would be other boys, all growing up in the love of Odiam, to live for it. When the doctor arrived an hour later, his services were needed after all. For Naomi gave birth to a little boy at dawn. HoME儔眅671笢恅趼躉捃濘
