Discussion in ‘Troubleshooting and Repair’ started by mikey, Oct 5, Need help repair dead switching power supply Reply to Thread. Search Forums Recent Posts. Oct 28, Sir 73’s de Edd, Your explanation on the lag response is understandable as you are also taking time to do several assists.
I appreciate your detailed writing on the theory side of diode. It is already shorted on diode test. Does it mean the response time of the 2A05 will be much slower than dkode SB? What is the danger or effect possible fire in putting in PSU for long term? FYI, the ohm series diode brown,black,brown,gold is associated to the cathode side of the other diode R this diode reads 1, off circuit and the diode is good.
2A05 (Diodes) – A RECTIFIER, Rectifier Diodes
I hope I am replying correctly to your question. Many thanks for your kind assist. Dioce look further to your help in making the dead PSU to work again.
From the information that I read earlierI was thinking that there was a good SB being used as one of the two diodes in the supply and also another one that had gone bad and that you had subbed in the 2A05 in its place.
In reality, one diode number that I had never known about was the R that you just now mentioned and it is the one associated with the series ohm resistor.
The main point of interest now, is to see what the voltage on the circuitry that WAS using the 2A05 is being now by using the R in circuitas compared to it when using the common generic 2A05 diode.
That’s being 3 times slower than the speed of the SB’s 55 nanoseconds. You are now free to test Thank you 73’s de Edd.
Equivalent for diode 2A05
Oct 31, Sir 73’s de Edd, Appreciate your great effort to do dlode explanation in a comprehensive manner. The info will come in handy to those who are eager to learn more on diagnosing dead non working PSU. With the common generic 2A05 diode replacing the original shorted SB, I am doing an initial testing by substituting light bulb series in place of the 5A glass fuse. This is to prevent a205 surge current to pass thru fully to the PSU thereby blowing other component.
Next, I switched off main AC power, unsolder the light bulb and replaced with the 5A glass fuse. I am a bit reluctant to do voltage test inside PSU esp. But due to its limited W power or lower I will use this PSU as a test bench for small equipment and most likely not used in on computer or sensitive equipment.
