PS3 Frankenstein PHAT PS3: CECHA with 40nm RSX

Hey man! Don't know if this will help or not but a month ago I fixed a CECHA01 which wasn't sending 5V to the drive. The problem ended up being C3247 (25V 47u) which was completely shorted to ground. It's also in parallel with C3246. C3247 was a tantalum cap on the COK-001 boards but was changed to a electrolytic cap (16V 39u) on the COK-002 board. It's not a perfect match to your situation but maybe the heat from replacing Q6010 caused one of the caps to go? I hope this helps!

Thanks for the tip. But I've been checking the console now for a few days with no issues. So yea replacing Q6009 solved it. It's worth mentioning that sometimes this problem triggered YLOD with an 1701 error. Perhaps when the transistor was shorting one of the voltage lines entirely to the ground
 
anyone who offers this service in germany? kindly pm me
if I am asking in the wrong place please forgive me, i really dont know where else to ask

Interesting thing I found today on Frankie #3.

The ELPIDA XDRs are very sensitive.
I touched one only very slightly while delidding Cell and the thing bent. It seems to use some really soft and easy to damage material on the edge area instead of the normal one. So weird.

Anyways, I found out you can mix and match XDR type. I put Samsung because I had no ELPIDA, had to reball him by hand, but everything working now.

I have a 65nm whit only 88 days of use (60 days when I got it ) I want to replace the GPU because I notice that it gets super hot like CPU is at 40 while it is at 60 I delided it and replace the thermal paste still the same issue

Nice sadly price's are way too high to get this done for the PS3 :ambivalence:

In Romania PS3 fats are so cheap like there a lot that are broken but cheap under 100 dollars the most expensive PS3 I saw was I think 100 dollars

This sheet is from @Computer Booter with readings from working 40nm RSX he's installed on other boards. Check your readings to see if they are close to his and you should be good!

Amazing. Thank you.

Unfortunatelly, many values are totally out of place. Maybe I (total newbie) did something wrong and cant even read ohms (lol)? Could somebody inspect these values, please?

VDDC 5.1ohm
VDDR 1.17kohm
VDDIORW 119.7kohm
VDDA 89.6kohm
VDDIO 18.71kohm
FBVDD 698ohm
 
I came here after watching the YLOD YouTube video by RIP-Felix. Amazing work on that video dude. I must say after reading and catching up on this thread some amazing work for this discovery. Well done for all those involved. A bit more about me I'm here as a new adopter of the PlayStation 3 after watching said video and after a long hiatus after the PS2. Although I did purchase a PS4 just to play Shenmue 3.

Having said that although i'm new to this scene I am definitely not new to the repair technician side of things, as a SMD repair technician over the years who has experience mainly in repairing laptops especially MacBooks of all sorts of sizes and models I'm hopefully able to offer any of my assistance in the technician sense to this community.

What are you guys doing for the supply of 40nm RSX's, currently I am not able to find any NOS for sale in the usual places like eBay or Ali express etc. So are we just harvesting them now from the existing PS3 slims out there?

When you are testing the Ω readings are you doing so with the RSX off the board at the respective test points?

I am testing them outside of the board and on the right points (I hope so). Is it possible that so many readings are out of ordinary values?

That might indicate that the chips themselves are not good. I've had one that had perfectly fine readings (was a pull from a slim) that generated 3034 on two separate consoles I put it on.

It's ok there is a possibility it could be a bad RSX, I know it sounds trivial but just to double check on your multimeter are you putting black probe to ground point and red probe to each respective test point?

Pretty much. It's going to be more reliable than sourcing from ebay or ali. There was one ebay seller that had NOS, and he was restocking every 2 to 6 weeks, but he hasn't had stock now for 3 or 4 months. At last we heard from him he said he didn't think there'd be any more.

So yeah, pull from donors. That's were we are now. The good ole days are over and now we enter into the mire that is pulling, testing, and hoping for the best.

I do both. On the board tests are mainly to see if a reball attempt went well. Just checking for shorts.

To see if the chip is good before using it in an attempt I ohm test off the board. But as shawn said that's unfortunately not 100%. @Computer Booter recently had two bad 40nm RSX pulls that ohm tested fine. It's better than nothing, but disappointing that we can't know for sure before trying. Booter had to reball that console a 3rd time to find an RSX that worked.
