Yay! Was able to repair one PSU by replacing a bad 18N60M2. Was thrown off by the 1.5V diode reading bc my Fluke reads Pin 8 at 0.816V on a known good.
Hi @ToltecMerc I have the same power supply that was blown up by a cockroach around the 40N60M2 mosfet and it took some fusible resistors and the ZM diode with it. I replaced the resistors at R7, R88 and the mosfet (still waiting for the ZM diodes to be delivered), and the DAP chip. I have 3 shorted capacitors at C85, C31, and C75. I recently asked you on JoeyDoesTech's stream if they were meant to be shorted and you told me C85 is meant to be 2.72ohms, C31 0.07ohms. I didn't know C75 was shorted at the time so I didn't ask you about it. Anyway. I tested all 3 of these caps out of circuit and they aren't shorted, however their respective solder pads short to eachother. Do you have any idea what it could be? I've probed around so much and just cannot seem to find the cause (keep in mind I am a beginner). I tested the mosfet at Q34 and I think it was reading around 360-430ohms. Somewhere in that range. Any bit of advice would be greatly appreciated. Thank you. EDIT: Welp. It's not actually shorted. The problem was just me not knowing how to properly operate/read a multimeter 😅 Thank you for your help!
HI, Could you help me identify a couple of components on the FR board please? one is a vener marked VM V1 (ZD39) and another is a diode marked GS5MB (D1) if you have mnuafactures codes that would be so helpful. I have had two supplies blow the R100 resistor (R96) as well as one of these diodes which i havent seen you come across yet
ZD39 should be marked ZM. It is a PDZ18B from NXP. GS5MB looks to be a general purpose 1000V, 5A diode. www.jjwdz.com/pdf/zhengliu/GS5AB~GS5MB%E4%BA%A7%E5%93%81%E8%A7%84%E6%A0%BC%E4%B9%A6.pdf
No, I don't believe so. This supplies shutdown very quickly when they detect any kind of problem. I don't believe it will send out gate pulses endlessly without seeing voltage from the feedback circuit.
Do you repair ps5 from viewers? I have one with a 400FR supply that was dead i replaced the power supply now it just beeps? I'll keep watching you are the best!
The rain made for a nice watch
It was an added touch! Thanks for watching!
What do you mean 🤔
@@Crystalservices it seems people liked it. It was a real storm.
Very Interesting, and Educational!! 2 Great Repairs, 1 Video. Thank You.
Glad you enjoyed it!
I really enjoy watching your method of troubleshooting. The thunder was nice ambiance!
Glad you enjoyed it! I totally planned that background thunder.
Great repair as usual, you the King on these repairs 🙂. Looking forward the the next 1
Thanks! Lots more to come!
many thanks for this video ... I'm also working in ps5/4 field ... you save my life carer
Good job mate 👍
Thanks for the visit!
Good job
Thanks!
I love your videos. They are so educational.
I'm glad you find them valuable. I have enjoyed making them.
Might eventually watch enough of these to get the guts to try one 🤣
Go for it! You're a wizard after all!

Are you on the East Coast? Here in central FL it's been rainy, sticky, gloomy, and cool for over a week now.
A little further west.
Thanx master ❤️🇹🇷
You're very welcome!
great repair again
Thank you very much!
nice repair as always
Thank you so much!
Master tech toltecmerc! You make it look easy but its not lol awesome jobs
Thanks 👍

11:25 to be sure the driver is good can’t you power up the PSU without the MOSFETs and check the gate signals with a oscilloscope?
No, I don't believe so. This supplies shutdown very quickly when they detect any kind of problem. I don't believe it will send out gate pulses endlessly without seeing voltage from the feedback circuit.

13:25 you mentioned 0.1ohm, is it the same one that ps4 has 0.16ohm 1 watt?
Hello. I have a burnt ic whose name I don't know. in ps5 edm-010 can you help me😢
If you email me a picture of the IC and the area around it, I might be able to identify. toltecmerc@gmail.com
Thank you 🌹. I sent the picture to your email.
Why are you not using desolder pump
It's not plugged in. By the time I get it plugged in and it gets up to temperature I can already finish the job with solder wick.
@@ToltecMercohh it's great 👍, I am talking about non electric manual one.
The swallowing sounds couldn't continue to watch i love every video repairs including your's but i can't continue I'm sorry 😂😂
Sorry. My sinuses are suffering right now.
@@ToltecMerc oh man i didn't mean to I'm really sorry hope you get better soon again I'm really sorry didn't mean it 🌹🌹
Please what is the part number of q34 mosfet
I know this is 4 months late but it is 2N7002K
Hopefully you've got your power supply all fixed by now though
@@Moby41 Not yet, I didn't know how to identify the part number of q34. Thanks for the reply I will order 2N7002k and try to fix my PSU
@@ngonohtc5724 Awesome. Best of luck and stay safe!
