It's like finding things, in the last place you look. That must have been tedious. Excellent Repair and Video! Merry Christmas to You and Yours!! Thank You.
Knowing the master's good luck, I told myself: he will have to replace all eight pieces. Another way to put it: when visiting Las Vegas or Atlantic City you should not try to bet on any type of event. However, with so much time watching your channel I knew you would go to the end of the road to rescue that console. A sincere congratulations. Thank you very much sir for sharing. A Merry Christmas to you and your entire family, and of course also to all the viewers/subscribers of this channel. Happy holidays to everyone from Mexico.
Imagine that, last two rams. Not an easy work ! I wonder if the simple re-flow would fix the problem, maybe it was only a bad solder ball connection. Awesome job on this one, for sure. Congrats!
It could have been a bad solder joint but I'm not sure if that would cause the exact problem I had. Who knows! I feel better changing it out. Thanks for watching and commenting!
Another nice result from a informed and methodical approach! If you would have started with 7&8, it would have been either 1 or 2 that was fried. Murphy, that pest! Merry Christmas from the PNW to you and yours somewhere! Looking forward to the 2025 repairs already!
Another one saved! Good job once again. It would be very helpful if you would tell us your hot air settings. I don't think novices like me will steal your job? LOL. Have a Merry Christmas and a Great New Year! Please keep them coming my friend. Stay safe. From Canada.
I was using 400C at max airflow with no nozzle on my Quick 861DW. I start off by trying to warm the board up in the area and then focus on ICs. Merry Christmas and Happy New Year from the US!
Good fix yet again Just one question what do you do with the ram chips you took off bin them or reball them for the next project Merry Christmas to you and your family 🎉
There could have been more than one possible ram issue as well. I'm also assuming you re-did the liquid metal. Are you able to test the other ram you removed? Cheers mate
It could have been multiple chips bad. I don't have an easy way to check them. Maybe with diode tests but I'm not sure if that would detect every failure. I have several donors with dead APUs. That's where these chips came from. Cheers!
Merry Christmas to you and yours sir. I was wondering if you have ever had any success replacing a TPM chip on a PS5. The TPM married to the board? I have an EDM-010. The RT5126 is not being provided 3.2 volts from the TPM chip. Myself and Stetofix are tag teaming this one. Just curious. Thank you.
Merry Christmas and Happy New Year to you as well! As far as I am aware, the TPM chip is married to the APU and the contents of the SSD NAND ICs. The TPM chip receives 3.3V from pin 7 of the RT5126/DA9065.
@ToltecMerc Oh, okay. We thought this was the other way around. I will replace the RT5126 and re-seat the TPM chip. Then see if I get my 3.3 back on pin 18. In theory I should. Thanks I will keep you posted.
Just an update: Replaced RT5126 with known good. Pin 18 of RT5126 still not producing 3.3v. Board is taking 30ma of current with 12v @ 1a applied. Thermal cam shows SSD controller heat up, followed by Richtek then Southbridge. After that there is nothing. Going to connect UART today and see what other mysteries are revealed. Board was a freebie from a seller on ebay.
Hi, thanks for sharing. I have a question to ask. It worked after you changed all the DDR RAMs, right? Maybe 3 or 4 or all of them were defected. How can you be sure that the 2 last ones are the defected ones?
When you replace RAM ICs, are they usually harvested from donors or do you buy them online? Ive got an EDM041 that im pretty sure has this same problem
I have some new ones but also several donor boards. They are somewhat expensive to buy new, especially if you are changing all 8 chips. I don't mix different brands of RAM ICs.
A pre-heater would be preferable but I often change them without it. I use my hot air station at 400C with maximum air flow and no nozzle installed. I try to heat up the board some before focusing the air on the chip. If the replacement chip is reballed with leaded solder balls, you could probably use less heat.
I use 400C at maximum air flow. I try to spread the heat around in the beginning and I haven't had a problem with warpage. Now when trying to remove and install PS5 APU, I have much warpage. Still trying to learn how to do it.
I don't recall how long it took but I'm sure it was several hours. Not really practical for a business. I'm not a business so I can take as long as I like on a repair.
@@ToltecMerc yes it is, unfortunately I don't have that UART, but I did detect a short on the 1.8V rail for the ram, I checked every cap there is dealing with that...its ALOT, since the ram chips weren't heating up at all. I ended up taking them off one by one till the short was gone, I took off 5,then , rebelled all..I don't have a stencil so that took some time lol, and there was no short again. Thanks for the videos, I like to watch them to relax. keep up the good work!
Wouldn't a Thermal Cam have saved some work and time? Usually it's either one that heats up more than the others OR One or Two may be running cooler which may indicate they need to be removed and reflowed.. Meh!!.. Anyway... APU👁👍
Hey @ToltecMerc have you ever worked on a PS5 that has the repeating crash loop in dash board? I got one with this symptom, the crash is anywhere from every few seconds to every few minutes, if I launch a game I can play no problems no crashes, and dashboard won’t crash if a game is loaded in the background. I’m wondering if it’s related to the 4GB Ram chip?
I don't recall seeing that exact problem. Bad RAM can cause lots of weird problems. Some of these random crash ones could be bad APU and just not fixable.
@@ToltecMerc There was a big dry spot and lots of dust in this unit, might be best to keep this one for myself as I can live with the annoyance and if APU I don’t know how long it would last before it becomes unusable.
merry christmas mr toltemerc and family ,and thank you for all the content you have given us :)
Thank you so much! Merry Christmas to you as well! More to come in the New Year!
I was getting a little concerned for a minute, but You did it! Well Done! Cheers!

Thankfully, I have never been much of a gambler. Thank you for the kind words! Merry Christmas and Happy New Year to you as well!
@@ToltecMerc Thank you for your response sir. I was a cashier at a gambling casino during my university days. Affectionate greeting.

super. so much patience and effort. perseverance wins. proud of you, so much work, and then there's the video editing. Merry Christmas
It did take a while. I did the reball off camera. Thanks for watching! Merry Christmas!
Awesome job my friend. Always love watching you bring these back to life. Thanks for the awesome content
Thank you very much sir! I have more to come!
Impressive you found the error so fast! And merry-xmas

A quality repair as per normal on this channel. Have a nice Chirstmas.
Thank you very much! Merry Christmas to you also!
thank you for all the videos you done though the year hope you have a merry Christmas and a happy new year
Thank you so much! Merry Christmas and Happy New Year to you as well!
Merry Christmas to you and yours. Thanks again for the video...
@@ToltecMerc ?
Sorry. I replied to the wrong comment.
Always the last one 😊 good job.
It seems that way sometimes. Thanks for the visit!
thanks for sharing the video..... Merry Christmas and Happy new year....
You are very welcome! Merry Christmas and Happy New Year to you as well!
Merry Christmas Sir, love to see your video for game console repair. There are PS5 service manual out there for free download.
Thank you! Merry Christmas to you also. I am aware of the files floating about.
RAM that's the hardest of them all job well done.👍👍👍
It is very tedious work. Thank you!
Good job mate 👏
Thanks 😁
Good work Merry Christmas
Thank you! Merry Christmas to you as well!
First , Merry Christmas and best wishes for you and your family.
First indeed! Thank you! Merry Christmas to you and your family!
@@ToltecMerc thank you.
Good fix yet again
Just one question what do you do with the ram chips you took off bin them or reball them for the next project
Merry Christmas to you and your family 🎉
The last 2 that are suspect will get binned. The other 6 are in a static bag waiting to get reballed.
@ToltecMerc thank you for the update 🙏
Very funny your reaction when you see the turn on-off 😅 you already know the outcome of that.
Honestly, I did not know. I did not expect it to work and was genuinely surprised!
Thanx master ❤️🇹🇷
You are quite welcome!
There could have been more than one possible ram issue as well. I'm also assuming you re-did the liquid metal. Are you able to test the other ram you removed? Cheers mate

Seams like it’s the bottom bank most of the time. At least for me. Nice fix.
I haven't seen a pattern. I hate to see errors on the corner RAM ICs as that is possibly pad damage under the APU. Thanks for watching!

How to connect RAM with pc ?
I don't know how you would connect it. You would need a ZIF socket and probably a microcontroller.
Hi, thanks for sharing. I have a question to ask. It worked after you changed all the DDR RAMs, right? Maybe 3 or 4 or all of them were defected. How can you be sure that the 2 last ones are the defected ones?
I can't be completely sure but I think it's doubtful there was more than one bad RAM. I don't have a way of testing them either.
What is the safe temperature for disassembling and assembling systems so as not to thermally damage them?
I use 400C at max airflow. I try to gently heat the board up in the area of the chip before concentrating heat on the IC.
@@ToltecMerc thanks 👍
When you replace RAM ICs, are they usually harvested from donors or do you buy them online? Ive got an EDM041 that im pretty sure has this same problem
I have some new ones but also several donor boards. They are somewhat expensive to buy new, especially if you are changing all 8 chips. I don't mix different brands of RAM ICs.
Hi merc, can you share the hot air profile for RAM reball, and whether one should use preheater or not.
A pre-heater would be preferable but I often change them without it. I use my hot air station at 400C with maximum air flow and no nozzle installed. I try to heat up the board some before focusing the air on the chip. If the replacement chip is reballed with leaded solder balls, you could probably use less heat.
Wouldn't the board warp without using a preheater, can you share temps used to replace ram ic's?
I use 400C at maximum air flow. I try to spread the heat around in the beginning and I haven't had a problem with warpage. Now when trying to remove and install PS5 APU, I have much warpage. Still trying to learn how to do it.
How long did it take you to repair and how much does it cost to do this type of repair? Thanks.
I don't recall how long it took but I'm sure it was several hours. Not really practical for a business. I'm not a business so I can take as long as I like on a repair.
I had this exact problem last week, it was the 5th chip I took off lol, it was ram 1 that was shorted.
It is so convenient when UART identifies the bad RAM IC.
@@ToltecMerc yes it is, unfortunately I don't have that UART, but I did detect a short on the 1.8V rail for the ram, I checked every cap there is dealing with that...its ALOT, since the ram chips weren't heating up at all.

In before anyone else waiting on you to get a wasted 30th anniversary edition.
I would love to get one of those! I'm not sure how many they made. Maybe a PS5 Pro in the future!
@ToltecMerc well, ive already seen a listing for one on FB marketplace. Dude wants $3,250 for it.
It’s always the last one isn’t it? ;)
It does seem that way for me and my luck! Thanks for stopping by Tony!

OR
One or Two may be running cooler which may indicate they
need to be removed and reflowed.. Meh!!.. Anyway...

Maybe. I have never had much luck finding bad RAM with a thermal cameras unless the chip was shorted.
don't throw them away! ill take them! the ram chips
