Thank you so much sir share your experience my smps problem will solved now ❤may god bless you sir

Thanks for the video. Have the same PSU for a HP Microserver N40L... it's dead. The chip you replaced seems good on mine (0.5V on the diode test). There's also 340V across the bulk cap so I think the HV primary is ok. None of the transistors appear to be shorted. The DC outputs aren't shorted either. I haven't figured out what is wrong with it. Btw, is the green wire the power good signal? Doesl jumping it to ground turn on the PSU?

Something i hate when i see high power transistor is blow up.. Mostly ic controller also blow up.. And difficult to find replacement

Excelent video, for you , wich brand is best for a psu? Gigabyte or Corsair

I've got a PSU that has the same symptoms - but couldn't get hold of the schematics for it. What's the standby IC type please?

i have a same card and same issue and i remove damge mosfet card is work but qustion is is it harm for the pc in ful lord

my laser level fasget 4d wont turn on if i connect it to external power source. like he need original battery with some electronics in it to work. but battery have only 2 connectors to laser so i dont think this is reason.

You helped me to fix mine. Thank you

I'd kindly ask for your sources on Google, found one guide from instructables that's really similar to this video but is missing the current limiting part, mind giving a hand here?

You saved mine, thank you very much!

Number of fault transistor pls

I know you may not want to respond to this but, are there tutorials (or do you plan to make them) on the DIY tools you use for these repairs? 😅

I have one of these but ive never used it. I want to make a bench power supply. It doesnt turn on. I found a ceramic fuze that has zero doesnt beep on the tone test. What pins were you using to diode amd restistamce test. The fuse being out is defba problem but i dont know what caused it. Its a cougar vte600 80+bronze. I got it at a bin store for 5 bucks. It ls bramd new it was an amazon return I think.

I have a Gigabyte P650B with similar layout to the one you shown - PSU is giving standby voltage but wont start - no easily identifiable issues. Have checked resistors and diodes and getting unusual reading from the same diode that was a problem in your PSU. Hwr, mine is marked as HSR1060 STC (was unable to find datasheet online) - assuming same as SR1060 (not sure what STC stands for ? - assuming initial H is manufacturers marking ?) All in all getting voltage drop of 0.18V (which seems quite low) and OL in other direction as expected. Beep test is OL on both. When measuring resistance 0,6kkOhm in one and abt 380 kOhm backwards. Assuming diode is bad but not fully burned ? Hoping for some feedback. Thank you.

Same problem, how did you resolve it?

Hello, I have the same Fluke and the same problem. Would it be possible for you to contact me in order to send it to you please? Thank you very much

Thanks so much. Let's get to 2K to get you that microscope 🎉

Hi, i have a problem with this scope, It dont work in oscilloscope mode, Someone can please help me ?

Cool, i like your style when it comes to videos

Nice vid. A bit longer is fine if technically required. I liked "I saved somebody 2 days of work".. that's exactly it!

Nice floor)

One question. How do you know the values and the types of the components burnt so to replace them ? Do you have schematics for this PSU or another similar ?

That burnt black residue is normally referred to as carbon.

Good , Thanks

Good Job

Hello Thanks, I am still waiting for the tutorial on how to make a test transformer

Sounds like the internal cooling fan is noisy. Those fans often go noisy on these fluke scopes. Also the charger input sockets fail often, too. I have several fluke scope meters and repaired the charging socket and fan issue on one of them with a video showing how I fixed it. Mine are colour versions of the fluke scope meters but very similar to the black and white screen versions. Lines across the screen is another common issue with that scope meter. If I remember correctly mine work off the charger without the battery installed. Well done repairing that one, good job.

Great repair. What is the board with the LED that you used to do the initial test?

this model is under active recall you could have just sent it back to deepcool. i had mine blow up and they replaced it with the v3 version in 2 days.

👍👍

good job mate

Hi, what’s the name of this resistor? Where would I find a replacement? Cheers 👋

thanks a lot , dear , if you did not replace the IC and replaced only the faulty w1p transistor ,, will it works?

spray a little of liquid to desolder 😂😂😂 5:10

I have a 65" sony with ac adapter ACDP-240E01. I could actually smell it over heating. Looks to be at the connection from the adapter to the tv. Haven't actually opened up yet to see if its something I could repair

Current regulation wasn't clear, what was the current regulating potentiometer connected to? Also, on a side note, something I've seen in another video, if you connect another double diode (half bridge of opposite polarity) in parallel with the existing half bridge at the main transformer output, you will also get a mirror of the existing voltage of opposite (negative) polarity. So, if you have 12v, you will also get -12v. Connecting accros the -12v point and +12v point will give you 24v output, basically, double of whatever voltage you have there.

Thnx a lot 👍

Long time no see! I waited for your new videos. Amazingly, components of newer PSU looked so complex, but with your master's touch, you were able to repair the standby voltage! Wonderful and exemplary procedures on how to fix them! Another computer PSU saved from being a garbage on the landfill! I hope more and more years of that PSU to serve. Greetings from Philippines! ^_^

Thank you. I learnt how to check for short of 12 3.3 and 5v from this video. I have antec bp450p with the same problem like yours. Mosfet, fuse and diode blown. Ordered parts and will try repair. And if I have a series lamp without isolating transformer, if there is a short when i power on, will it affect other devices? Two of my psu got blown and wondering if it is possible!

Promo`SM 💃

good video. whats the fuse value? i see normally fuse is glass type what do u call the fuse that is broken in this video ,

My daughter decided to give mine a bath. I had to take it apart to dry out the laser as it was full of water but the 3 very thin wires broke off the small baughter board for the LED. And I'm unsure what order they go back on. I've soldered them back but the laser doesn't work now. Your video skips any parts of this. Any chance of adding a few closeups of the wires?

You make it look so easy which is the sign of a good tech. Good repair 😊👍

Cool

Hi. I use the same psu, Few days ago when i turned on the power to my multi plug, there was a single click sound(which actually sounded like a switch was clicked) that came from my psu. But the actual connection to the was off psu was off, i have the whole muti plug connection grounded. After the click there is an ambient noise coming from the psu, it isn't anything loud but it's just so quite that you can hear it which wasn't there before. Pc works just fine. Should i be worried about the ambient noise coming from the psu? Please share your insight on this one, it will help me a lot 😊

My power supply was also damaged. IC901(TNY268P) seems to be fine, but I will replace it to be sure. In my case, the R902 resistor was damaged (burned). Does anyone know what resistance it should have? I couldn't find a schematic for this particular power supply.

What is spesific Diode? 4148 / Zener Diode or something else?

Same issue. Thanks😊

This power supply (Delta DPS-150TB) is used in a HP ProLiant MicroServer N40L. These MicroServers are used as a home/office NAS. The power supply in my server has just failed. So it might be a similar fix to get mine going again.

Very concise and lucrative .
