#93 Repair of PS4 PCB SAC-001 Fast Shutdown

[@n4_ku]

Please bless us with at least 2 videos a week.

[@ToltecMerc]

I'm not sure if i can do that but I will see what I can do.

[@seguramlk]

YES

[@TyronneManners]

Nice work! I remember the days when I used to do this for work. Reballing using the stencil and flux is not an easy task to do...especially filling in balls individually afterwards and lining everything up so hats off to you. Seeing that resistor reminds me that I have a SAC-001 board that someone destroyed and knocked off several components....but it's hard to find a good close up photo so lord knows if I'll ever get it going without watching more videos like yours. Great setup with the microscope and rework station + board heater!

[@hudsonpearcy7648]

First time watching your videos and I have to say I love the way you show the whole process without cutting the camera off. When I get my reflow station hopefully I can fix my old PS4. Love your videos! please keep making more.

[@ToltecMerc]

Thank you so much! I'm glad you like them. I will do my best to make more!

I have he manny console and know every PlayStation like the back of my hand.I had a few of these models.I don’t have the ability to do surgery on a APU like this.what I do is take the plate that bolts down the heat sink.I bend it and it applys pressure to the board and this model is good to go.the ps3 fat boy is currently the only console maid by PlayStation that I can’t bring back to life.I enjoyed your video and wish could have got into this type of work at a younger age.your a wise man looking back on what I was doing it was because the APU ball joints had failed.I guess you could say I’m hands on with my work.thank you for this video I learned a lot.

#93 Fixing PS4 PCB SAC-001 Quick Shutdown Very impressive video, fascinating stuff!

[@ToltecMerc]

Thank you very much!

[@MasterJediSean]

After all that work, it was a Resistor! that figures eh? In any case that re-ball will help keep this in good working order for some time. I am happy for the win! I thought that this was a no-fix but once again you worked your magic. Good work my friend! I look forward to your future videos. Cheers!

[@Foxx_69]

Ive been contemplating a BGA rework station. Amazing you can pull those off so clean! its just a hobby for me, so its a tough call

[@ToltecMerc]

It's the same for me. As it is a hobby, I can't justify probably a couple thousand dollars for a decent BGA rework station. Plus, these PS4s are just not worth what they once were.

[@Foxx_69]

Ya. Thats the other thing. Nobody wants the ps4. Xbox one s is still an ok money maker. Phones still are the easiest flip in my area

[@Console_Tech]

Another enjoyable video.

[@ToltecMerc]

Thanks so much!

[@OwnVybEntertainment]

I get no 1 volt to the coils...what should i do?

[@amurara3012]

Hi, im with same board and same problem, but i dont get the 1,5v on memory capacitors, the others (12v, 1v and 1v) i could mesure, in fact the capacitors from memory coil are shorted, what do you sugest? Tks a lot for your videos, im learnig so much. Sorry for my english and a hug from brazil

[@ToltecMerc]

If you have a true short on the RAM voltage (1.35V) you need to find it. It could be a RAM IC or a capacitor on the 1.35V rail. There are many small ceramic capacitors on the 1.35V rail. Can you inject 1V on that rail and look for heat?

[@johnrazor8720]

It looked like alignment of the stencil was difficult. Also I would be interested in how easy the stencil comes off after you flow the solder balls. Perhaps a complete tutorial on the next BGA you do? Thanks for continuing to share your experience as we all learn.

[@ToltecMerc]

With this stencil, you remove it before heating the balls. I think this stencil would immediately warp if I heated it.

[@johnrazor8720]

Thanks, I don’t know why but I thought they were metal, perhaps stainless. Glad you cleared that up for me.

[@ToltecMerc]

@@johnrazor8720 oh the stencil is definitely metal. Very thin and delicate metal.

[@jonathansandiford4137]

@@ToltecMerc I tried. It definitely warped

[@anthonyboccardo2726]

Different type of stencils allow you to heat them as u suggested called "direct heat stencils" this stencil used isn't one of those.

[@Daveyk021]

On the remounting of the APU, how could you tell it was soldered? In some videos I've watch, you can see the chip actually "find home"/sift a bit. Some will show (with smaller IC) the chip "dancing" a bit with wiggling the airflow. In this case, I saw nothing. I did not see the chip shift, sink, or do nothing. If that is case, how do you know you have fully soldered it? (Sorry, I am trying to learn how to replace a much smaller PowerPC chip and have yet to be successful. There is also an FPGA, I would like to learn to change that only has ball connections around the outer edges of the chip, so it shouldn't be as difficult (no heatsink pad in the center). Do you have the airflow set to min/middle/max? I wish I had someone local I could learn from, but I do not.

[@ToltecMerc]

I nudged it at the bottom and top. I'm sure it was hard to notice because of how far away the camera was. I nudge it very gently and watch for it to snap back. The balls are so close together on the APU, if you nudge too hard you risk the balls moving and merging underneath.

[@josef19dz]

Professionnel work 😮 nice master

[@ToltecMerc]

Thank you! I’m glad you enjoyed!

[@marionycon9488]

Recalling the chip is always my biggest problem, what temperature and amount of Flux you use. Please 🙏

[@ToltecMerc]

Use a minimum of flux. I just spread it really thin with my fingertip. I probably used around 415C with very low airflow. My airflow goes from 0-120. I was on 20.

[@ceejay_gaming9636]

@@ToltecMercwhat temps did you use to remove the APU ?

[@ikeabuchi1]

Excellent video once again👌

[@ToltecMerc]

Thanks! I appreciate that!

[@Daveyk021]

After all that re-balling work and you found the resistor, I had to go "Doh!" for you. lol

[@ToltecMerc]

The reball was needed as well. I didn't edit this very well. The APU voltages were there before the reball and missing afterwards. Somewhere in between I must have broke that resistor. Also, I was able to make it boot normally until it overheated by pushing down on one corner of the APU. I didn't get that recorded.

QUE VOLTAGE Y AMPERAJE LE TIENE QUE LLEGAR A LA CPU

[@argee99]

Nice, very nice. Really enjoyed this one. Thanks...

[@carlosgarciaoropeza5480]

I did not see the scale "thumbs up" x 1 Mega. I would have chosen her without hesitation! All the best.

[@WagnerSilva-fq2tu]

Great as always! If you let us to know. What are the settings for you air gun to the spheres don't go away? What flux do you use? Thanks.

[@ToltecMerc]

My quick 861DW has airflow adjustable from 0-120. I was using an airflow of 20 at about 420C. My flux is cheap Kingbo RMA-218.

[@BienExplicao]

Hermano una consulta. En la línea de 12V tengo un corto. Pero a diferencia de este video, los condensadores no están en corto. Pero después de los Mosfet FDMF 6840C, las bobinas y los siguientes condensadores están en corto. Incluyendo los condensadores que están en la otra parte cerca de las Memorias Ram. Cómo podría saber cuál es el componente en corto? Y cómo podría hacer para solucionar?

[@OkayAhhgain]

Can I send you a ps5 that has the blue light that stays on with no signal. A repair shop replaced the hdmi and they said it might be the cpu

[@vendrick420]

Very satisfying as ever!

[@ToltecMerc]

Thank You! I'm glad you enjoyed!

[@JonnyFix]

I hate doing a tonne of work to find out it was something simple. Good result though. Was very tempted to buy a large BGA rework station once, if I did I might have ended up saying yes to a whole lot more headaches like trusting I'd put a million balls on correctly!

[@ToltecMerc]

Oh the BGA reball was necessary. I was able to get it to boot once by pressing on the corner of the APU. I wasn't recording then. Also, after the reball, I had no APU power at all. I had APU power before the reball. I had to have knocked that resistor loose during the rework. I don't think I could have ever had APU power without it.

[@M.altarhoni2024]

You awsome 👍👍 happy repair Good luck sir

[@ToltecMerc]

Thanks, you too!

@@ToltecMerc by the way I have tested the new TEA is the replacement for DAp053T and i confirm that it works fine and tested the console about 2 weeks ago.. just still not tested under external load as i have just recived my dc electric load only few days ago .. Thanks again for sharing your knoledge Keep going 🫡

[@jonathansandiford4137]

What Temps are you using with your hot air station? And is it a quick or an atten. I need to find that nozzle for my atten st-862d. Thanks for the video.

[@ToltecMerc]

It is a Quick 861DW. I was using 360C when removing and installing the APU. The preheater does the rest. The nozzle is not specifically for my Quick. It is a generic one that I modified slightly to allow it to attach to the Quick.

[@pakiisam6075]

Great Video. What temperature do you use on your hot air station to remove the APU, is a "QUICK" station? and what temperature on the pre heater?

[@3absisoRA]

From my experience... I think the problem was the resistor from the first place not the APU

[@ToltecMerc]

Except I had the APU and RAM voltages before the reball. They were totally missing afterwards. No APU core voltages and no RAM voltage. That's what made me suspicious that I had done something.

[@petel6856]

@@ToltecMerc Very good work. You are definitely a Play Station wizard. I've learned tons from watching your vids. Keep it up. Did you create the square adapter you put on your hot air station?

[@Morscode_Gaming]

Do you mind sharing what settings you use on your hot air for this sort of APU reball? I try asking others, even people i know defer to your wisdom who just tell me not to use that preheater and hot air. Yet ive seen many videos of people doing it successfully. I gather its about being smart and emulating a BGA profile not just smashing it with heat 😊 TIA appreciate another great video.

[@ToltecMerc]

I preheat the board unitil it is around 110C, then I use about 360C from above with the wide square BGA nozzle. I use 350C when reinstalling because the APU will have leaded balls then.

[@Morscode_Gaming]

@@ToltecMerc thank you sir :) time to start practising on some junk boards

[@fluffy_preacher]

I have the original ps4 the one with the light strip on the top and mine just started doing that a few weeks ago, not sure the exact problem tho, did the longest time my controller would just shut off and would just blink white then turn off then a few minutes later I would loose as wireless connectivity and would have to pull the plug while powered on to fix the issue

When I try to turn it on, it does the same thing, but I have to push it again to turn it off so I can repush it to see the blue light come on for a second.

Yes, but I would like one with square holes so I could use solder paste.

very good. reball to apu is welcome. when you manually place the balls on the apu, clean the place well with ipa, then apply flux very, very little, so the balls stay in place and do not move when you heat them.
