[Answered] Rare YLOD symptoms in PS3 help?
I use it horizontally. It does turn off when cold. For example, I haven't used it for 24hrs, then right now I decided to use it,
1. turned on and stayed on for 7 secs, it beeps 3 times the shows the yellow light then flashes red until I touch the power button again.
2. turned on for the second time and only lasted 18 secs, it beeps 3 times the shows the yellow light then flashes red until I touch the power button again.
3. turned on for the third time and only lasted 7 secs, it beeps 3 times the shows the yellow light then flashes red until I touch the power button again.
4. turned on for the fourth time and this time it stays on forever If i dont try to run games.
After trying to run a game it turns off... it beeps 3 times the shows the yellow light then flashes red until I touch the power button again. I have to do those 4 steps fast so the console can get a little warmup because if try to turn it on leaving minutes pass by between power on's the console will keep going to step 1 as stated above. Its like the console needs a warmup to work, but then fails to load games. The console is in a very ventilated area with 2 12v fans attached to it.
It has 3.55CFW installed.
UPDATE: I did the reflow on it and it did not get better nor worse, its just doing the same thing as explained above. what other things could cause this?
The temperatures of the cpu and rsx gathered by multiman are the following,
After the fourth time of turning it on, I played a 3d bluray movie and it never shutdown, but it will shutdown with any game.
my advice is try and get another psu as checking the ps3 for current is very dangerous. on top of that i think you covered every other possibility, it really does seem like a psu problem. anyway try and get a new psu because unless you like 20-30 amps of current going through your body (thats enough to kill) its actually not worth it.
silly question - is your fan inside your ps3 working?
if you insist on checking your own psu then you need to remove it then attach a crocodile clip to the metal outside and join the other end to the ps3 shielding metal then get a bit of wire and attach one end to one of the metal prongs on the ps3 (avoiding shorts) and the other end of that cable where the prong fits in the psu then for the other side attach positive lead of multimeter where other prong would go and attach negative lead to the second prong on the ps3 mainboard (all connections should be secure as if any slip it may fry your machine worse than it is).
