Ps3 YLoD Attempted fix's. Any more ideas?

Well I cant say i've disected a power supply before but I do know there are two power connectors on the PS3, one presumably for high power items and the other 8 pin connector for the lower power parts. I would think this is why the PS has 2 fuses as IMO its a dual power unit. You may be powering up only one side of it giving you the startup..Again this is all speculation.

 

this is a hard fuse to find. i turned the board over and dont even see the marking they use for a fuse.. i must be overlooking it. do you need to take anything off to see it??

 

So I reapplied the Thermal Compound to slightly positive results. The machine is running at the 3rd level fan speed at idle and I can play a game for about a half an hour before it gets up to the 5th fan speed. So I think it could be bad quality paste? It was like 2 bucks at Radioshack, it doesn't have any kind of rating on it. It's silicone based though, I looked up a chart and they all seem to perform about the same. It's just odd that it used to operate on a much lower fan speed, and blow much hotter air.

 

Sounds good dude. I've reflowed my unit four times now and I'm sick of it. However I cranked up the heat on my last reflow from 300C to 500C (for a shorter time of course)and it's already run longer than any of the other reflows. I still suspect it will YLoD again soon, but with the flux and the extra heat I'm hoping I can make my next fix a long lasting one.

 

Great news guys! I've repaired my ylod again, i didn't use flux but i "fastened" the screws really hard and put washers to the screws that hold the heatsink to the motherboard. This time the baby is still quiet after 3 hours of playing infamous. This is really good because first time after 3 minutes the fan kicked into high gear and it was really loud!

Thanks for the tip Panedi. And again thank you Gilksy!

Hope it lasts this time!

 

no probs m8 good luck hope it lasts
and yes well done Panedi for the extra suggestion of the washers to give more preasure on the heatsink plates this is why its good to get your views out into the open!
ITS A HARD AND LONG BATTLE TO FIGHT AS ONE!!!!!!

BUT AS MANY WE WILL BE VICTORIOUS!!!!!!!!!!!!!

THE REVOLUTION HAS STARTED....STICK THAT IN YOUR PIPE AND SMOKE IT!!!

SONY!!!!!!!!!

 

Please tell me how you fixed it because mine is doing the same thing, the green screen thing...

 

Wow... so I removed the old crap compound, put on a very thin layer of Arctic Silver 5, bent the clamps for extra pressure, and... it's superhuman. Like... it's never run this well. Ever. The fan is blowing lower than I thought possible even under a decent load. The heat sink is extracting the heat very well. I'm amazed. Thanks a million, Gilksy. Add me if you'd like, PSN- Ace_Pheonix. And a question, are the initial units you repaired still kicking? People say it'll fail again, but I can't see why it would if it's not getting that hot.

 

yes there still going fine!

 

well i got my ps3 in that had YLOD on it. got it for 37.00 bucks. and put my motherboard in the ps3 and i stil have no hdmi or Av outputs. so my kid damaged something on my motherboard. not too worried about it got a working motherboard for 5.50. so im going to try collins guide and see if i can get this other ps3 to work.

 

Hi there,

Just need a little bit of advice. My PS3 did the famous YLOD the other day. I followed Gilsksy's guide to repair it put it all back together and now it won't start up, the red standby light is on and when I press the on and off button nothing happens! I hope I havnt fried it. I used a heat gun at a temperature of roughly 350celcius maybe a little higher and followed the instructions properly. Any help would be appreciated.

Thanks

 

i got the Gilsksy's guide to work on my ylod but forgot to plug in the fan. it ylod again and may have killied it.. still trying

 

reconnect the power ribbon!!!
that may be the fault!!!
make sure its fully inserted before you lock the tab down!!!
gilksy

 

Doubt you've killed it, I did the same and it works just fine

 

this will not permanently kill your ps3 you merely sped up what happened in the first place!!!!!!!!

do the reflow again this time 400degrees Celsius and an extra 10 seconds on the heat
also apply liquid flux before the reflow and try bending the heat sink clamps so they apply more pressure on those bga'S

and all should be good!!!!!!!!

gilksy

 

already did all the above. instead of liquid i use pasted from my job in refrigeration where we soldier alot of stuff. if i knew it wouldnt hurt to run 8% soldier in there i would do it. this is 4th time im trying after fan was not hooked up.

 

Hi again,

Do you mean the small ribbon that connects the small pcb to the main board, the one with the on and off and eject touch button on it?

Thanks

 

if i read that write you added solderpaste? 8%solder?

if so then no wonder it doesn't work youve probably cause a solder short or theres a solder ball stuck between two pads under the bga causing a short!

the only way you going to fix that if you havent blown one of the many surface mount fuses on the mother board is to remove/reball and refit the bga's

gilksy

 

yes that one!
