SCPH-1000 PS2 Graphic Issues?

Thank you!



By the way, it turns out, the problem is very common.
(Not just the guys on the forum, but also on the Yahoo auction).
I wonder what's going on with this chip?
l_oliveira, pictured this chip?
Is it important whether the lower mark, or I can order СKR61 Texas Instruments?

 

The chip on the PS2 is somewhat application specific... You can have sure the chip you found at the site is the same one used on the PS2 ?

Yes, that's the chip I was talking about. It's the clock synthesizer for EE. The clock it generates is divided internally on EE and then sent to IOP. From IOP it goes to the DVD drive, DEV9 (PCMCIA bay), SPU2 and other circuits. Hence the slowdown behavior on sound.


Oh and this is my "educated guess" on why this chip fails:

http://en.wikipedia.org/wiki/Electromigration


This passage being of particular interest:
"Although electromigration damage ultimately results in failure of the affected IC, the first symptoms are intermittent glitches, and are quite challenging to diagnose. As some interconnects fail before others, the circuit exhibits seemingly random errors, which may be indistinguishable from other failure mechanisms (such as electrostatic discharge damage). In a laboratory setting, electromigration failure is readily imaged with an electron microscope, as interconnect erosion leaves telltale visual markers on the metal layers of the IC."

 

That is, should be the same all the letters on the marking label? I think that finding exactly will be difficult.

 

Maybe buy a few if they're cheap and try them out on the console ?

 

I shall search. What's the difference between the various CKR61? (Except the type of case chip).

 

I wouldn't know, really...

 

Does anyone know what's the difference between the chips?
On sale are:CKR61PWR,CKR6107,CKR6108.
Which chip is suitable for PS2 (SCPH-10000)?

 

So ... Story continues.
CKR61, Texas Instruments, Case TSSOP16.
If anyone is interested, I found it here: http://www.littlediode.com. Expensive, but worldwide shipping.
The letters and numbers below "CKR61" likely indicating the production date, batch number, etc.
Old chip I deleted, the new - soldered.
The result was very interesting. As I wrote, the console froze old CKR61 after 10 minutes. With the new chip it froze after 30 minutes after the first activation. After the disappointment and sleep (Repair I did at night), I turned on the console for the second time. She worked 2.5 hours. Then he began to stutter and slow down the sound, but the image remains stable!!! (Previously, it was vice versa). I will continue to supervise (repair I did 3 days ago), but would love to know what else is not working correctly? What are the opinions?

 

Well, it might have other faults too. With such a motherboard fault it's possible that it was being tested without the top cover and the area around the EE and GS chips might have overheated a bit.

Another fault that is common is cracked joints under the IOP chip or on the IOP EDO RAM chip (the long chip near the USB ports).

Edit:

The particular SCPH-15000 console I repaired with the CKR61 fault had not seen much abuse. I went straight to it's clock gen chip after I saw the IOP clock slowing down while crashed.

 

Thanks for the info, I'll keep looking.
I warm up the motherboard underneath these chips, maybe it will help.

 

Today I repaired another SCPH-10000 unit that was freezing. I went straight to the CKR61 chip. It's now working ... lol

I took a known good CKR61 chip from another unit which had a known fault on another chip (the IOP chip was dead).


Edit: Just so people know what these are, they are "DRCG Lite" chips (Direct Rambus Clock Generator). The PS2 10k has two DRCG Lite chips, one on the bottom (pictured) and one on the top. The one on the bottom (pictured) generates clock for the EE chip and that in turn generates clock for the rest of the console. This one is set to run at 300Mhz.

The one on the top generates clock for the RDRAM chips and for the EE (DRAM controller part only, for sync with the RDRAMs). On my consoles the top one is usually a Cypress CY2212 chip. But I am sure a CKR61 works at the up spot, too. This one is set to run at 400Mhz.

 

It took 2 years, but better late than never.
All brilliant - easy.
In my case, besides the CKR-61 needed replace the fan. (Although the old seems to be working fine ...). So that in addition to the CKR-61 it was banal overheating. With the new fan (and new CKR-61), freezing stopped - for two months no once (with hard drive and without, games, music CDs, Linux)
l_oliveira, thank you again for the explanation of the causes of the problem.

 

Thanks for this post, I got my 10000 machine working again by replacing the DRCG chip near EE and GS chip.
