MY SCREEN TURNED BLACK


Is this a power cut off or a blank. If poweer is not present then the supply voltage to the circuits must be studied and rectified.
however if the volages arre present then it can be failure of the display processor/drives.

Since a recent power failure the printer will not turn on.


It is possible that the power supply in the printer has failed. You will need to open the power supply unit whichcis within the printer. Open the panels and get acess to the power supply which is a SMPS- switch mode poweer supply. Start from the fuse, the surge protector which could be short or the mains rectifier, mains capaccitor or the SM driver. Replace and proceed.Check for short inthe secondary side for fusible resisistors opening, for diode shorting or zener shorting. Also check for the optocoupler which feedsback the switch. Use a good multimeter to check. If you are not familiar ask a friend with electonics knowledge to help. However if you visibly notice a fault of a burnout replace and proceed. hope this helps. Good day

Not getting power on my t2882 e-machine.


I am an emachine specialist. These computer suffer with problem motherboards which often blow the power supply unit. Replacing the power supply on it's own does not solve the problem as the motherboard processor socket is the cause of the problem, the fault in turn blows the power supply. The same applies to all Advent and Medion computers sold via the high street stores.

HP Desktop power up problem


Bad ram probably, units do that all the time at my job. Most of the time, it is the power supply that does not have enough power to invest into all hardware that makes your pc. even if you had a 400watts power supply, the next time you are buying a power supply you should do some kind of upgrade. 600 watts or more. If you have a high end graphics card then you are indeed in need of a new power supply. also check your cpu, its fan, check if it still seated properly, if there still paste on top of it to hel cooling it down, and protect it from statics. if you added new hardware, remove them and keep checking if it is working. To do manual diags, you need to take the unit apart. I would start by removing rams first, and check ram one by one, then hdd, then disconnect other components until i find the actual part. I am sure it is your powersupply, worst case scenario is you mobo is gone.(but it powers up and shutdown after all so let us hope you don't have a dead motherboard." and remove the dust please, dusty units do not run properly.
