Ps3 YLoD Attempted fix's. Any more ideas?

Every reflows why not reball and confirm no solder bridge as well it will be 100% after a reball
Reball takes longer but better reults and I keep reading that people are reflowing more than once so one reball should do it

 

Does anybody know if there are any user videos of this whole process? Someone going through it as necessary. I understand some people are using different heat guns, and hair dyers =p , and different temps but I'm just curious. Tried looking around but didn't find anything. Was just wondering.

 

I know some point out the major things but anyone else know where the fuses are and what they go to etc.

This is one of my boards btw

 

In progress next week, but note I am going to try a slightly different approach than the cook-cool-and-flip method.

I would recommend a sacrificial PCB (like an old video card) to practice on to get the approximate time and temperatures.

Remember to do this outside... although it is Lead free it will still have some nasty fire retardants in the board.

Do not put a blob in the center or you may damage the chip.

Try pieces of scotch tape down each edge
Apply thermal grease
Run your scraper edge along the top of the tape
remove tape to leave your stenciled tile
repeat for other surfaces

CTRwannaB,
The fuse is a ceramic type located in the high voltage section of the power supply block.

btw, that is one filthy board -- a vacuum and 99% alcohol wash will do wonders.

Remember, cats like the warmth -- but can't buy you a new ps3 =)

 

Sorry I was too lazy to clean it lol.
I know about the fuses in the Power Supply Unit.

I'm mainly looking for certain fuses on the mobo, as there seem to be dozens of them

Maybe the one that makes the PS3 shut off right when it turns on.

Yes, I already tried a working PSU.

I know theres a blown fuse on the Mobo somewhere, heard it pop

 

Would somebody pls explane me the difference between reball\reflow?
Thx

 

Reball (difficult even with tools):
remove the chips from PCB
clean pcb pads and chips (tricky)
prep chips with flux
replace the solder covered balls on the chip
align the chip precisely where it was ($1500 rework station)
heat bond

Reflow (easy and this thread's theme):
heat until the solder melts (and hope it bonds the cracks)

btw, a solder bridge is uncommon if already successfully bonded

Just remember:
It will likely get bricked if you bump of move anything when the bonds are hot!

 

Ok man thx... now i got it... but my question is... if we are talking about a bridge... and supposly i get to fix mine everytime i reflow cause the sistem starts... what happen when it get hot again... and why... after 20 min max 30 min my ps3 give me the F*****g ylod... do i need to increase the time of "heating".. im about to do it for like 2 minutes each zone....
we'll see what will happen...

 

Ok guys i reflowed for 2 minutes at 1000F (i know im crazy) but now its been on for 50 minutes... so... im going to let you guys know if i completely fixed it.... im shaking... lol

 

hello guys, i just got YLOD on my ps3 yersteday ...before 2 months i got my blu ray drive dead (could not play blu ray only ) where i switched it with a use blu ray lens KEM-400aaa and it worked like a charm for arround 2 months until yersteday that got the YLOD....

i am pretty sure it happened from heat because one day before it happened the console closed by its own (was playing all day RE5) but next morning it worked normally till the evening where i opened it for 20 mins and got the YLOD ..

colin i need to know something , do i have to use the heat gun on BOTH CPU GPU and on BOTH sides of the chips in the motherboard? and the temperature must be 350C and 2 inches away from the MOBO ? please man i would like a reply from you asap!

i wanna do this because even if the console works for at least 30 minutes i will rush on take my SAVES backed up cause I CANT AFFORD on loosing them...damn sony!

 

See that's crazy, 2 min at 1kF?
I'm just not sure with all these different results/reports - some working longer than others, some not working, some just returning to the YLOD. All these different times and temps, if you were to push that 1000F any further would you be at a real risk of warping/ruining the MB? That's one thing I'd be worried about, cause, yeah. =/

 

ok guys it less for 1 hour and then it went off again...
with the yellow light... any suggestion?

 

PerryIta: Do you know if it does this because of heat problems or not? Does the fan speed up quite a lot and is the air really hot coming out of the vents?

 

Quick update... if i let it cool now it start again.... so i guess with that big reflow i did something good.... but still after a couple of minutes it shut off... so guys i dont know what to do... im scared of try the 2.5 minutes at 1000f and i know that 2.5 minutes at 700f is not gona change a thing... maybe i just should remove the extra fan i bought... or maybe not i dont know what to do... all i know is that im not gona give up... now that i see chenges.... im startinf to believe that it is possible for me to fix it... so if someone has some advise.. pls help me...
btw guys, i never used to write on forums, but now i gotta say that this one is very helpfull, and that there are a lot of people ready to help others.... so guys like colin says.... we have to screw this company SON* that is great of makeing consolle but that just dnt wanna admit that a overheat problem happened 1 month after the 1 year warranty.... should be repaired for free... but i heard somewhere that nobody is perfect... so... keep trying...:d

 

yes.. with my first tryes the air used to come out really hot and just after 5 min... but the fan didnt speed up... now with like i call(big reflow) it stayed cool for like 15 minutes then warm and then after 1 hour hot..... i have to say that i putted on an extra fan... so i dnt know if the fan is the problem for me.... witch i dnt think so... its defenatly a overheating problem... just trying to figure out how to solve it... we have to work like a team.. so i sugggest if anyone discovers something new with varios tryes... well should let everybody know about it... cmon guys... i fell like im so f******g close...

 

Well what temp does the solder melt in the PS3?
Because certain solder melt at certain temps.

If your going doing 1k F, man all solder melt at that temp.

Your doing more harm then good I think. Whats the GPU/CPU temp threshold?

 

Damn, see it is encouraging to know that it at least started working again. Even if it just turns off, its still progress, right?! Why did you replace the fan with your own, or did you somehow rig up an additional fan???

 

If it is heat it may possibly be the heatsink or compound not mounted corectly and causing it to shutdown immediately. I am still having problems with getting the correct thermal compound amount and its so frustrating and so it gets super hot really quickly so you may want to investigate into that a little bit more. I hope you solve it!

 

See that's what I was thinking, 1kF is f*cking hot! hah, I mean, I don't want to risk warping of the mb or something by going that hot, obviously he is progressing in temp but hey, if it's lasting longer even at that heat, maybe its nearly there. i dunno tho, that's crazy cause that's pretty warm

 

537'C (1000'f) is too hot, if held on long enough it will damage parts, and may create toxic fumes.

Generally:
300'C For bonding BGA chips
320'C For rework of already bonded chips (ideal)

Slightly hotter if the solder has oxidized a bit.
