#70 Repair of PS4 CUH-1215A No Power

[@DovClk]

Thank you so very much ! your fantastic pencil diagram of the voltage limiting Zener circuit helped me indefinitely .Your captivating and informative videos are a true pleasure to watch !

[@ToltecMerc]

I'm glad that helped! I'll try to do more illustrations going forward.

[@toolsarecool]

Another great one! I noticed when you wicked off solder from one of the fusible resistor legs, there briefly is another component leg visible that didn’t appear to get resoldered (@ around 13:30), but I am sure you caught that off camera. 😎 Happy New Year & thanks for all the awesome educational content this year. You are a YT gem IMHO. 👏

[@ToltecMerc]

Actually I only noticed it while editing. I have to go back and touch that up. Good eye though!!

[@orion310591RS]

@@ToltecMerc Good eye really, I have seen this at some other youtubers, actually viewers see the footage and tell where was mistake. One more reason NOT to use fast forward or NOT to delete footage. (We have keyboard arrows if we want to skip something, you make footage as real as possible, even if its 4hrs... take your time)

I want to Thank you alot about very detailed explaination you really give me a big push forward anf in each video i learn somthing new .. thanks alot One question what is zener specifications used in ps4 ? My regards

[@ToltecMerc]

Your are quite welcome! 9.1V is common in slim supplies.

[@junks345]

Happy New Year ToltecMerc. 🥂 Inspirational and entertaining. Thanks for the content

My issue is that the adp-200er gives 4.8v and also 4.7v on the 4th pin (ac_in) but as soon as I short pin 3 (ac_stby) and 4, 12V comes up and goes off and within a second, the 9.1v zener, the 0.16ohm resistor and the 5v mosfet blows. What could the problem be? The power supply stays on in standby for a long time without any issue. I already replaced dap041 (with ld5760) and dda001ag ic.

[@ToltecMerc]

Perhaps the power factor corrector is putting out too much voltage. It should be 395V across the big caps when 12V is enabled.

[@Trucam2020]

As usual an excellent video.

[@ToltecMerc]

Thank you so much!

Hello Master This is a good and educational video like always Using a variable transformer is a smart choice and you can add a series lamp to reduce the current I love watching your videos Have a happy and fun Holidays GOD bless you

Amazing work bro good content

[@ToltecMerc]

Thanks so much! I appreciate the comment!

[@jonathansandiford4137]

Hey m8, I'm having a hard time getting these 0.16 ohm resistors. Where do you buy them from? They are out of stock on mouser and digikey last time I checked.

[@ToltecMerc]

Yeah I noticed Digi-Key was out of stock recently. Luckily I had bought 100 of them. I have not found another source. Sorry.

[@jonathansandiford4137]

@@ToltecMerc ok cool. No worries m8, thanks

Thank you! I will try my best!

Can you help me The zener short but when I replaced the zener it still short, I made sure the zener was good,

[@PUBG_PERSIA]

Hello ! I have one of these psu and everything is fine but some one before me worked on board and he can't fix it now when i short the 5v and acdc standby 5v standby goes down i dont know where i am searching for problem

[@Steve_be]

Nice work as always

[@ToltecMerc]

Thank you sir! I do appreciate that!

[@cristiansantos5742]

Great job !Gracias

[@VorjuMeidear]

You don't have a shopping list by any chance? :) Seems like it's all the exact same for my PSU.

[@Magsyboy]

Damn, ur a wizard

[@ToltecMerc]

Thank you for stopping by and commenting. More coming!

[@riparaggi]

Happy New Year! those 1200 button switches always got broken. I repaired a power button also 2 days ago, weak design indeed

[@ToltecMerc]

Thank you. I have replaced so many of those switches. I also have the plastic button tops on hand. Happy New Year!

[@saadakram6938]

Dear sir, hope you will be doing great, I need little assistance regarding an issue I’m having with my ps4 power supply ADP 200er, I’m not getting voltage at stand by the fusible resistor is open although replaced but still it gets off, their is some component shot but I can’t find it the mosfet 3n62k on meter says short when it is on the supply board but when I disconnect it it doesn’t show sighs of short please help me out.

Great video , greeting from Iraq

Thank You! Greetings from the US.

[@Widya-v4s]

my zener is good...i think the line zener is short can you tell me what wrong??

[@ToltecMerc]

If your zener is good, you should measure 1.0 ohm across the zener. Not 0.0 ohms. If the zener has shorted, your MOSFET may have shorted or the DAP041 IC has failed.

[@Widya-v4s]

@@ToltecMerc ok, the mosfet short can you tell me , what kind this mosfet ?? because i dont have it and how ampere this mosfet?
