As for all you people with the "oven" trick, I'm glad it worked but it's by far the worst method of doing things. Your heating the entire board when the heat should be focused on just ONE chip. @ikoiou, you used the oven trick on the board 5 times in 2 years. My first "heatgunned" console still works from 2009 with about one reflow a year. In 2010 I got an actual reflow station and I still have to reflow the board yearly; heatgun damage caused irreversable board flexing. A launch 60GB was also reflowed in 2010. Never reflowed again; I used a proper reflow station and focused heat on only the GPU. My launch date 60GB has NO reflows. Replaced the thermal paste as soon as warranty was up on top of and under the heatspreadders and it's easily as quiet as a year old slim. For the future, I suggest nobody does the oven trick. Replace the thermal paste under the heatspreadders and make sure your heatsinks make flat contact with the ps3 chips. Older PS3s are known to NOT do that.
OP, replace your HDD. Check your BluRay cable. Restore the system. If a disc is recognized by the XMB it's not the BluRay cables. Make sure all screws are in the right place. Make sure there's no grounding issues with the board. Take it apart, place the board on a piece of cardboard for a couple seconds and rebuild it. Should get rid of any static if there is any.
I have finally got it going again.
Thankfully, I never did damage the CPU and I know NOT to do that again. Thank you! I noticed that the BluRay drive would not eject any disc or even take one. I looked again at the ribbon and it was flexed as I noticed before. I flexed it back to shape carefully, and the BluRay drive finally started working, and I can now launch applications.
Thanks for the support, and advice.
Spoke too soon. Haha.
The screen graphically glitched out, and the YLOD came back. I was monitoring the temperatures, and I got about 40 on the CPU, and 50 on the RSX at idle. Not really enough for overheating, but I am hoping that's what it is this time again. Maybe, my sensors are fibbing?
Also, should you re-apply new thermal paste each time you rip it from the motherboard covers? I used Arctic Silver 5 (High Density) thermal paste. It has been recently replaced along with some of the thermal pads that were brittle.
Done a third reflow (did not touch the CPU). No problems so far. Just trying to work out the averages for the temperatures.
I seem to be having a stream of bad luck.
So, having already reformatted my hard drive, and getting the system to boot up, I had to reinstall everything. Once I did that, I began downloading a game from PS Store that I already brought, and the download was going to take a while on my connection, so I decided to just turn the TV off, and let the PS3 download while I slept. I woke up the morning to find the PS3 on stand-by. I assumed it had over heated, but it turned on fine. No problem.
So, when I went to access PSN, it said I had to update my firmware. So, I checked my firmware version, and it was 4.21 (spoofed). So, I accidentally clicked an update (which updates the firmware - CFW related), and out of panic, I flipped the switch at the back. Now, when I turn my PS3 on, I get no video output, however the screen briefly flickers but it is barely noticeable. I can access the recovery menu just fine. I first checked to see if it was my hard drive by turning the PS3 on, off at the back, removing the hard drive, and turning it back on (in the way to access the recovery menu). After a few minutes of no video output, I got the warning about the system could not boot (hard drive not detected). So, I turned it off, placed the hard drive back in, and turned it back on. Still nothing.
I am assuming I have messed up the software by turning it off due to a update, so now what I am trying to do is update to 3.55 OFW, and re-install CFW. I have the things I need, but the problem is when I go to 'System Update' in the recovery menu, the system just freezes (display remains the same). I cannot leave it on for too long since it does overheat until I change the fan speed manually which I am unable to do now until I get back into XMB once I've reinstalled everything.
Is the freezing normal? And should I give it time to start the update process?
I haven't done any reflows. I have only reapplyed thermal paste to the GPU and CPU. I'll buy heat gun but what temp. should should i run it at and for how long? What are the heatspreadders, and if i were to apply thermal pasteuld dynex work
I dont suggest any kinds that fixing PS3 using a oven, that is impractical way of fixing a ps3, same as heat gun.
If you want a not so hassle to do kind of reflowing the motherboard, first you need to flux the processor you want to reflow (the BGA) and do preheat the motherboard Using Hot Air station in low air setting at 80c do it for 3minutes then you go to reflow process by raising the temp to 100-120c (depends on PS3) for another 3 minutes, once done leave the PS3 for 10minutes and reassemble the ps3.
But all of this YLOD jobs that I done so far is I do reball all of them and also changing the thermal paste by removing the IHS both of the processors and replace with MX-5 AS for CPU and AS Thermal Adhesive Paste for GPU. CPU needs a epoxy to put back the IHS on it.
i also used the heat gun method for all of the ps3s i have done... have a dual temperature digital reader with lines on the board next to gpu to make sure board isnt getting to hot... i bought 3 ps3s for 50$ all of them had ylod... fixed 2 out of 3 replaced thermal paste on cpu and gpu heatspreader and underneath gpu heatspreader... Question 1.. do i pull off the cpu heatspreader and also do underneath or just leave it on? rsx heatspreader is known for coming off when the fan comes out but never seen cellone heatspreader do that... question 2... 1 of the 3 ps3s i bought boots up to the beginning of xmb dash where it says ps3 on screen.. the fan then kicks into over drive and it blinks red then green and then just blinks red. cant see any yellow. anyways does this have to do with to little or to much thermal paste or are their some type of heat sensor dealy giving a false reading? ive heard some say there is no heat sensor and some say there is. but you know what they say. believe none of what you hear and half of what you see. ive never actually seen this heat sensor but im guessing its embedded in the cpu or gpu but idk. hope you dont mind me posting here i cant seem to find something similar to my problem...
Nevermind figured out what was going on. the rsx heatspreader on the gpu slid slightly off the gpu therefore wasnt passing the heat it was suppose to.
