Ylod After Fix PLEASE HELP

So recently i bough a phat console of a friend. Within two weeks the console had got ylod. I watched videos and decided the repair was easy enough so i got arctic silver 5 and got to work. However when i put the ps3 back together the console still had the ylod. From then i have tried suggested things such as testing the fan (which works fine)

and making sure that the thermal paste is thinly spread across the chips and that the heatsinks have a good connection etc. Also a few days ago the ps3 booted up for the first time and worked fine for about 20-30 secs . Ever since the console has not worked at all PLEASE HELP

Answered! View the answer I have this problem too

@jmacked first you will have to remember that there are a few things that can cause the YLOD. A few of them are:

A dead or disconnected HDD

Cold-Joint between the CPU/RSX/EE(If your console has one)

A dead power supply

Overheating

Corrupted NAND Flash

You most likely have issues with your GPU processor. It is a flip chip design and the issue could be the solder bumps between the IC and the substrate. A reflow might fix it for a while but even reflows are very limited. YLOD (as well as RROD on a Xbox) are caused by the design of the processor, not necessarily by bad or cracked solder joints. The only repair that would fix it permanently is a new BGA. Try this repair and you may have to change the approach a bit by adjusting the heat. It is a hit and miss situation and most first time failure with this is caused by not applying to much heat, whereas to much will totally remove the IC's. Anyhow, the biggest reason for failure to reflow is not enough consistent heat. There is a fine line between reflowing and absolutely melting the solder, so one needs to be aggressive without going over board. If nothing else, get a couple of temperature probes and see what heat you generate. Replace the thermal paste again, do not add to it. The AS5 thermal paste alone will not prevent a YLOD. Apply it according to their specs and it should not give you any issues. You might want to contact the game console guru and see what he thinks.
