Yep! It's not always a happy ending but thanks for coming along for the ride!

Thank you very much! More to come soon I hope.

It was an interesting one! I'm glad you enjoyed it!

My pleasure!

The flux under the crystal has bitten me several times before. It was only in the last year or so that I realized what was happening after South Bridge replacements.

The slims seem to act differently from the fats when that oscillator is missing. Don't forget to check the battery too!

@@ToltecMerc sure, don't even think I did not try a different battery before diving into replacing SB ;-) My kit is missing an oscilloscope however, would help to visualize that clock... There are some RTC related errors on UART output though, which initially got me into trying all clock related stuff. I'll update here once I get back to it, could be days. I do this as a hobby like you, so good there is no-one breathing in my back waiting.

​@@ToltecMerc ​ like said I would update on my slim, but too sad it is still a failure... I swapped the oscillator and this time both caps, leaving the area clean from flux and residue, but the unit keeps behaving the same. Funny enough, while measuring for the 3V battery bus close to SB, I noticed that the diode connecting 3v3 bus with it was bad (causing draining of 3V batt towards 3v3)... I was like hell, it must be this then, but still no; now the 3V batt voltage maintains ok, but it did not fix the issue... I did a bunch of other stuff too, bricked the NOR once in the process, etc, no good. It's just like the unit does not know how to reboot; trying the "reboot" option in safe mode does shutdown too (like 10sec white light + shutdown)... I think I'll just park this one until I get my hands on another working board of exact same model... Or just scrap for parts

Thank You!!! I'll do my best.

Thank you for watching and commenting!

Thank you! It was a fun ride!

Thanks 👍

Thank you so much! That is very kind of you!

Big thanks!

50% of the time it works every time!

Thanks!

Thank You! I had fun with this one. I may have accidentally learned something as well.

Thanks! I'll think about that.

Like most things it's intimidating until you do it and then it's easy.

I was not sure that a flat battery could cause that during an update, but it makes sense now. Thanks for the info sir!

@@ToltecMerc not sure if you know of @Steve be but definitely would recommend you checking his channel out also and see the knowledge the guy has. He hasnt posted much recently but you can certainly learn a thing or 2. @Steve be hope yr getting better pal, hope to see you soon also

@@ToltecMerc its not common but every time i have encountered this problem the cell has been dead

It really is impossible to get accurate readings in circuit. If I test in circuit, I'm usually looking for a shorted capacitor or a completely open resistor. You won't get accurate resistance readings but if you have the same circuit repeating (like around RAM ICs) you should get similar readings across them. Sometime you are just looking for something that is way out from the normal.

@@ToltecMerc brilliant explanation thank you

The NOR Validator will tell you the offset in the summary. In this case, it started at 0x1CA000. It wasn't a lot of bytes. Maybe a 100 or so that I had to copy.

@@ToltecMerc very cool. Your videos should be the top rated console repair videos on KZfaq. Very informative and a great variety of issues. Thankyou for sharing the knowledge. 🙏

I have never worked on a PS3.

@@ToltecMerc My problem is i tried on my ps3 replace hdmi encoder chip on enother but I get "ylod",so in your experience with ps4's did you get same mistake (blod i mean) from fault replacement ?Sorry for this little stupid question ))I don't know what I did wrong in my replacement.

Have you connected to the internet and let the system update the time automatically? I think Sony did something in the later firmware to prevent the time from being remembered unless you let the system update from their servers first.

I run into this one about half of the systems I run into. It’s usually systems that I’ve recovered to 9.00 but I’ve also seen it with updated systems. The unit need to be updated to set via online. Sometimes that seems to make it hold. Even when unplugged. I’ve seen it with a factory SB, swapped it. Still won’t hold time. I’ve been looking for this answer for a while now. But I know it’s not the SB

@@ToltecMerc Yes I should have mentioned that, I did update the firmware to 10.01 and I connected to PSN. Sometimes it won't let me even sync the time via the internet, it gives me an error when I try. Very frustrating as everything else is working perfectly.

@@albertdavis1882 My ps4 was on 9.00 and I updated to 10.01 (don't want to jailbreak this one) and connected to PSN, even played online games, still looses time. Even in rest mode it looses time when I wake it back up. I can't find anything online about anyone having this problem which is strange.

I'm not sure if I can help but you can email me. toltecmerc@gmail.com

Ok I will.

Possible but I don't think so this time.
