I am working on a Samsung scx8040 and it is a service call that another company began but did not finish. A massive electrical discrepancy sent voltage spikes through the machine. Unfortunately the service company that was there before me did not find the power issue and installed a bunch of new boards and an incorrect hard drive. When I first saw the machine it would not turn on. Power supply board had 9 blown capacitors so I replaced that board. All of the other boards seem to be fine and I don't really smell any funky electrical and I was testing positive for continuity. I instructed the customer to have facilities fix the outlet and I returned with an innavolt. When I powered on the machine it went into system recovery mode. I do not have access to the original hard drive and and my resources are unable to explain to me what package is supposed to be installed on the hard drive that is referred to in the service manual for formatting. I decided to try firmware and it would not load. I spoke with many Samsung technicians and suppliers and they were unable to give me an exact answer but agreed that firmware might be what the service manual was talking about. After continuing to try firmware I realize like a bonehead I didn't check to see that they had installed the right HDD. I ordered the hard drive and turned on the machine now it's giving me a s1-3110 video System error code. The USB has continuity and the hard drive is brand new. I found some vents back metal on what seems to be a fax joint board so I unplugged that and power down the machine with the same result. I did the same with the hard drive unplugged which brought me to system recovery mode but it's hard to load firmware when there's no hard drive LOL. Does anyone have any idea what I should be looking for here? Like I said the boards look pretty ok but even if I was given a list of the replaced parts so far, I cannot trust that they used a safety barrier between the machine and the circuit. end user has been without their copier for a month now and the way theyre forced to procure from higher up puts them in a difficult situation where the offered equipment for replacement would not satisfy their Network needs or their volume needs. Help would be inanely appreciated
