Kyocera MA5500ifx Won't Power On (Warning Light Stays On)
Hey everybody! I've got a relatively new MA5500ifx (installed in February of this year) from a client's office that is completely dead.
The machine was functioning completely normal up until it wasn't. After this weekend when the client's got into their office, they noticed that there was no functionality what so ever.
I came out, switched the power cords, the outlet, and eventually took the machine back with me to swap the boards and gave them a loaner.
When the machine is plugged in, the only thing that turn on is the warning light on the front of the machine. No fans, no noises, just that light.
Here's what I've done so far
- Swapped the power cables and outlets
- Checked wire connections throughout the machine
- Visually inspected PWB's throughout for any issue
- Swapped out the Power Supply PWB
There was a rattling noise coming from the old power supply PWB when you moved it around which isn't present on the new board.
The only troubleshooting steps that are left in the service manual are checking and/or replacing the Relay-R PWB or the Controller PWB?
Is there a way that I can determine which one it is without ordering the replacement part? I'm not super familiar with identifying issues on circuit boards.
If these other two potential replacements don't do it, what other steps can I try?
Reply to Ropariva - Yeah, I think you're right. I'm not an expert with circuit boards, but read some levels from the Relay-R PWB & the new Power Supply PWB, and it looks like the controller has to be the issue. I placed an order for the Main/Controller PWB.
Reply to kuby? - No, I don't think it was a storm. The MFP was on a surge protector with other electronics that were working just fine when I was at the client's site.
Reply to copykat93? - If you're asking about a reading, I didn't do one specifically for the main switch. Based on the other reading I got, I was able to determine that it was the controller.
Additional Question
Upon closer inspection, I noticed that the sticker on the back of the fax board looked yellowed. Almost like it had been heated up or aged for a long time.
All of the other stickers in the machine look new, so that's why it stuck out to me. I included a picture of the sticker in the post and the board doesn't look to have any other "burn" indicators.
Do you think something happened to the fax board as well? If so, does putting the fax board back in with the new controller once it comes risk damaging the controller again?
A favorite resort of the foreign residents of Yokohama during the summer months is the island of Enoshima. It is about twenty miles away, and is a noted place of pilgrimage for the Japanese, on account of certain shrines that are reputed to have a sacred character. Doctor Bronson arranged that his party should pay a visit to this island, as it was an interesting spot, and they could have a glimpse of Japanese life in the rural districts, and among the fishermen of the coast. "But as we are in for it," he continued, "we must make the best of the situation, and hope to go through in safety. Many a strong ship lies at the bottom of the sea, where she was sent by just such a storm as we are about to pass through, and many another has barely escaped. I was once on a ship in the China seas, when the captain told the passengers that it would be a miracle if we remained half an hour longer afloat. But hardly had he done speaking when the wind fell, the storm abated, and we were safe. The typhoon is to these waters what the hurricane is to the West Indies; it is liable to blow at any time between April and September, and is often fearfully destructive. OPIUM-PIPE. OPIUM-PIPE. "Surely your ladyship knows Dr. Bruce!" Hetty said with a vivid splash of colour on either cheek "A little time ago I understood that Dr. Bruce----" "I require that everywhere a strict investigation shall take place into the conduct of the soldiers with regard to the life and property of the civilian population. "Where were they buried?" They all pressed forward. "Count out. That's the only fair way," shouted the boys in the center. "Now, there's three loaves o' bread for the Sargint," said Harry, laying them down on a newspaper. "There's three for the Corpril; there's three for me; there's three for you." "'T?un't peas, thick 'un," Vennal would break in uproariously, "it's turnips—each of 'em got a root like my fist." At this moment of perplexity, some medicine, that she had obtained from Edith, occurred to her, and, with a feeling of confidence, and almost of extacy, she took a phial from a shelf in a cupboard where she had placed it, and, pouring out the contents in a large spoon, hesitated an instant ere she administered it. "Let me see," said she; "surely it was a large spoonful Edith told me to give—yet all that was in the phial doesn't fill the spoon. Surely I can't be wrong: no—I remember she said a large spoonful, and we didn't talk of any thing else—so I must be right." But Mary still hesitated, till, hearing a sudden noise in the court-yard, which, she conjectured, was her mistress returned, and as the child was getting worse every moment, she leaned back its head, and, forcing open its mouth, compelled the patient, though with difficulty, to swallow its death. The draught was taken; the rigid muscles relaxed, and for a minute the child lay motionless in her lap; but in an instant after, Mary could scarcely suppress a shriek at the horrid sight that met her gaze. The eyes opened, and glared, and seemed as if starting from the head—the fair face and the red lips, were blue, deepening and deepening, till settling in blackness—the limbs contracted—the mouth opened, and displayed a tongue discoloured and swollen—then came a writhing and heaving of the body, and a low, agonized moan: and, as Mary looked almost frantic at this dreadful sight, Edith's words, when she had given her the phial, "that there was enough there to kill," suddenly occurred to her—and then, too, came, with a dreadful distinctness, the remembrance of the true directions which Edith had given. It was nearly noon the next day, when the under-sheriff entered the room to ask if their opinions were yet unanimous. The galleyman still refused. "That for ye, coward," said Tyler, striking him with the flat side of his bared weapon. Oakley aimed another thrust which was again turned aside, and the smith, now flinging down his sword, seized upon his right hand and wrenched the dagger from its grasp. After a short struggle, Oakley fell heavily on the pavement with the blood streaming from his mouth and nostrils. HoME萝拉泷泽第4部资源
