#41 Repair of PS4 Slim No Power

[@thierryfranchet8930]

You are so skilled to troubleshoot faults. I hope you will work on PS5 because there's a lot of "no power issues" that i'm sure you can fix. Continue your great work !

[@ToltecMerc]

I just picked up a PS5 with No Power. Working on it today!

[@thierryfranchet8930]

@@ToltecMerc Awesome ! @TheCod3r shares a lot on KZbin to troobleshoot this kind of fault. But even if he passed to fix lots of PS5 sometimes it's a rabbit hole. But if the problem come from the PSU i'm really impatient to see how you'll work on it.

Never cease to impress. Bravo

[@ToltecMerc]

Thank you very much sir!

At 27:18 how did you know that it wasn't a multi layer PCB and that that the lane didn't just pass through to another layer?

[@benjaminwillis9259]

Best tutorials I've seen

[@ToltecMerc]

Thank you! I'm glad you enjoyed.

Hi, have you tried installing NCP1399 instead of DAP 049? They say that they are similar, but I wonder if this is true.. I will be grateful for your answer! Good repairs

[@ToltecMerc]

I have tried an NCP13992AB. It worked somewhat. It could be an NCP13992AF but I was unable to find any of those.

can the 4A fuse be replaced by regular glass fuse of 4A? thats the only one available locally. also i have a blown dnp012ah chip. If i remove this chip should the standby 4.8v be still available once i replace the fuse (the resistor r1 is fine)?

[@ToltecMerc]

A regular 4A fuse should work but should probably be a slow blow. I have not tried running a supply without the DNP012AH installed. That IC is the overall supervisor of the supply. Give it a try.

Hi, good day, sir. I recently working for N160A006P (medel no: N17-160P1A), thus the issue was that there was absolutely no 12 volt output. But, there is 4.8 volt solid state standby power available. I've discovered that the board's PFC is only at 320 volts and won't go up to 400 volts, and the PFC IC is only receiving 1.16 volts when it should be 12 volts. Could you help advise me as to how to obtain 12 volts to the PFC IC? I'm trapped with this.

what are the parameters of the J3K4 zener diode, I can't find it anywhere

Another great video my friend. I've seen that red soldering mat before online but can't recall which one it is. I like the large minimal look of it. Do you know which mat it is? No biggy if not I'll find it. Keep up the great work my friend. Top notch.

[@ToltecMerc]

Thank You! Here is the mat: www.amazon.com/gp/product/B017R4DQHU/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&th=1

Inspiring fix. Definitely getting an oscilloscope

[@jonathansandiford4137]

I have this exact problem with the 15v supply "wondering" but at idle. my 5v standby wont come up. I think it might be a bad ld5760 batch from china again as I cant find anything shorted.

[@ToltecMerc]

I have gotten some fake LD5760. They are out there. Still waiting on some good ones myself.

[@pipassassin1212]

Hi can u tell me if there is a difference between dap049 and dap049b

[@ToltecMerc]

To be honest, I'm not sure. Sorry.

[@PinoyPSP3000]

Can you share the link of the device used to compare the 2 boards . Keep it coming please , I had learned more from your videos .

Sure: www.ucore-electronics.com/product/uce-ct220l-tracer/

Nice Jeep

[@ToltecMerc]

Thanks. 2005. Bought it new.

[@wrh0627]

Do you still reccomend the ucore?

[@ToltecMerc]

I like it and it's neat. That being said, I can't say that I have used it a whole lot lately.

[@abdulmajeedabdulrazak7162]

Standby 4.8 voltage is gone after 12v loading (means short 5vsb and acdc stby) components look like ok , standbye VCC also fluctuating (DAP 046 vcc down to 10 to 11 volt) this complaint coming ps4 fat,slim and pro also , please explain

I love psu repair videos, obrigado

Good job mate 👍

How did you learned brother

[@ToltecMerc]

I've been an electronics tech for over 30 years. I only recently got into gaming consoles as a hobby. The more you work on, the more you learn.

[@livekorafor24h]

@@ToltecMerc bro i mean how can i learn repair in general how do i start

[@ToltecMerc]

@@livekorafor24h buy a broken item that interests you and work on that. You learn by doing. There are lots of forums to ask questions and videos on KZbin. You can’t learn everything at once.

[@livekorafor24h]

@@ToltecMerc yeah i want to learn basics to start

[@albertdavis1882]

Just a PSU issue?

[@ToltecMerc]

Yes. Some physical damage to the power supply PCB and a shorted IC.

[@diegomr6969]

you need the acin_detect 4,8v too !!!! is the pin1

[@ToltecMerc]

ACIN_Detect is basically a power good signal from the power supply to the PS4 mainboard.
