Well, i made this section a few weeks ago but i just didn't ever put anything on it. Until now. First i would like to thank the community for their valuable feedback on the ViStart 7 release. I have already started working on the next build to try to address the bugs mentioned on the ViStart bugs board. I will be releasing that around Christmas hopefully. Anyway yesterday my brother came to me, he was quite depressed because his Playstation3 decided to YLOD (Yellow Light of Death). I did some research and it was what i had suspected. The YLOD is pretty much the equivalent of the Xbox360's RROD. "General Hardware Fault". 80% of the time for PS3's, this is apparently caused by cold solder joints between CPU/GPU and motherboard. The Japanese Launch Units had a slightly different design than the more recent units. Sony quickly changed their design in a desperate attempt to fix YLOD or potential YLOD units.

What's more amusing is how Sony are dealing with this problem.
Quote
The failure rate of PS3 is 0.5 %, (which is less than the accepted failure rate for electrical goods), compared to the 360 which was around the 30% mark. That number is substantially less now but still much higher than that of the PS3 and the accepted failure rate for electrical goods.
BBC Watchdog apparently launched their own investigation on the matter. Which invoked this amusing response from Sony
Quote
“We entirely refute the suggestion that PS3 consoles have an inherent defect or other design issue which is akin to any warranty issue experienced by another console manufacturer. “From the correspondence to date, I have serious concerns as to the accuracy of these allegations and the likely tone of the Watchdog report. The information that you have provided suggests a fundamental misunderstanding of the technical issues and a mis-characterisation of SCE UK’s OOW repairs policy.

Is my brother one of the 0.5% people affected (remember, these figures are calculated by Sony and obviously cannot be trusted. Just like Microsoft's fake figures of the RROD failures). Well maybe he is that unlucky. Anyway a few years ago a Japanese guy told me about what he called the "sony timer" theory. Apparently it's well known. Although it could just be small minority of people who have been very unlucky with Sony products. Although i am sure it would be more than 0.5%  Wink (since it's a well known theory). He proposed that Sony intentionally engineer defects in their products which causes the product to fail just short of the warranty period. The only problem with that theory is that we know Sony sell PS3's at a loss. So i looked at how much a PS3 would be to get repaired officially, apparently it's around the £130 mark for YLOD. Although the BBC Watchdog crew made it look like it should be a £5 job. From i could tell in the video. They simply disassembled the units and reflowed.  (The same effects could be achieved with a heat gun) So i did what they did only i used a heat gun instead. It worked great. If anyone decides to copy me (Which i take no responsibility for) then i recommend using a temperature controlled heat gun set on the lowest blow-speed and around 350 C. You should probably follow a guide. gilksy1 does a good guide. You can watch his youtube video here; http://www.youtube.com/watch?v=U70SgRDVcBo

Happy un-LYOD-ing  Wink

My PS3 died 3 years after I bought it. I am going to reflow my PS3, but I don't have a controlled heatgun. I need No-Clean Flux and Artic Silver Thermal Paste. The reason why my PS3 broke was due to the thermal pasting on the GPU completely drying off.

Also, not sure if the repair stations of Sony US is different from Japan's repair stations. But in Japan, when they repair a YLOD unit, they remove the main heat inducing chips and surrounding chips. They then re-apply new solder pasting and re-heat the board. That is what I saw when I went to Japan for a business class trip.

Got me a PS3 slim now, and my 60gb Launch PS3 is still disassembled in my living room table. Another note on the reflowing, if you don't reflow with flux applied, then the PS3 will get YLOD again due to the weakened solder joints.

Arctic silver?  That's old and not-so-reliable nowadays Tongue Arctic Cooling MX-3 is a lot better Cheesy

Hmm Arctic Cooling huh? I'll look into that. As long as it last long and has adequate heat absorption.

Yes, though I haven't personally tried it many people find Arctic Cooling MX-2 to be much better than Arctic Silver 5.  Arctic Cooling MX-3 is a newer, even better version of this.  I'm getting a tube soon for my PC when I replace my heatsink.

You could probably do what I did to repair my graphics card, put it in the oven. Do some googling, there are guides as well as youtube videos concerning this unconventional technique.

I've known about the oven technique for quite sometime. Although a very risky technique to do. Since all the heat has to be focused on the top of the board, and has to be carefully monitored. If the chips on the bottom of the board heat up too much, they will fall off... then your screwed.

Yes, that is a problem, but actually a friend of mine said that sony is actually coming out with a new way to put the components together so you can do ultra easy modding
