    Hey guys, I have been using my launch NTSC J ps2 for the last few months with no problems at all. I decided to move it back from the gf's house and set it up with linux, keyboard, and mouse etc.. It's been running great for about a week, playing games, and booting to linux no probs. yesterday I had it freeze while booting PSBBN, and then i noticed the "boot" audio was slow and slightly noisy/dirty! So i thought.. It must be HDD or HDD software problems... No. Even with the ps2 connected to only the TV and power cord, it will boot 5 times out of ten, then freeze or glitch with slow glitchy sound...:nightmare:

    I did swap out the 110v power supply for a 240v when i bought it, so i thought it may be failing. I re-installed the original 110v supply, and dug out my step-down transformer. Still get the same symptoms.... Tell me its NOT DOOMED PLEASE???? I love my PS2.....

    Also, I have an official Sony PS2 scart cable. Do they only support 4:3 aspect ratio, as I get huge black borders with it, and none with a cheapo 3rd party lead?? Thanks.

    Sounds like the board might be damaged. As far as PS2s go the 10000 is rather easy to to work on. FYI the 240 power supply is probably 3rd party unless someone was stupid enough to scrap a debug, the 1x000 units used a power supply that is incompatible with any other version. Third party units can be rather unreliable, that could blow components on the board so check near the power supply connector for burned components.

    Hi, You are right about the power supply's. I had several DTL-H10000 PS2's, some were beyond saving so i kept the power supplies as spares for my SCPH-10000!! The debug DTL's I had were 240 volts, so they are official Sony.. tried the two 240's and the 110 it came with.... I hate to admit it, but i'm guessing the GPU is cooked..

    SCPH-10000 runs at 8.5V that's why it's powersupply has a different shape.

    Newer units use 12V PSUs due to them having internal HDD.


    But there's something to observe here:

    GH-008 (AB-Chassis) SCPH-18000 units have a 12V power supply which fits on the SCPH-10000 chassis. O_O
    Serious danger of damage.

    Sounds like your unit has bit the dirt (clock generator circuits have gone), like mine has just. :/

    But I think that my Kisarazu unit has multiple issues, since the random freezes still persist, despite the audio (audio was played at a low tone) and slow clock rate issues disappearing (Perhaps I fixed that by soldering, after all). D:

    The freezes that remain are weird, because they occur randomly, and it depended strongly on the running program. Stuff like the OSD seem to be able to keep running forever, while some heavy games like Valkyrie Profile 2 would freeze up within 5 minutes of gameplay. D:

    l_Oliveira should be able to tell you what's wrong here. But for both of my units, it was quite obviously the system clock generator that was gone (Sound was weird, with the one on my Minokamo unit varying in tone). For my Kisarazu unit, the EE RDRAM clock generator might be malfunctioning too.

    Thanks guys, SP193 you're description of the tone changing then glitching/freezing is what is happening. Could any of these symptoms be from over heating components? The reason I say this is, after leaving it overnight, it is working perfectly now.!!!! It's been on for about 25 minutes.. And counting.. In my limited experience... Things don't fix themselves. Confused!

    Oxidization, dirt, cracked joints, bad capacitors ....


    So having it warm causes it to work properly.

    It'll be back... for revenge. :(

    If it's one of those common faults that l_Oliveria just listed, you'll be probably considered better off. Assuming that my units have the same problem as the SCPH-15000 unit (S. KOHDA) l_Oliveira fixed, it's... a faulty chip that needs replacement. D:

    Originally, the low sound tone (as well as slow performance) problem occurred after my unit heated up for a while. Soldering originally did nothing to fix it... but that suddenly disappeared. The freezing problem, however, still persists (and it happens after a while too).

    Thanks again guys for your help. You were right. 30 minutes in and freezing again. Time to look for another 10000/15000/18000.. Shame, it is a super minty clean and scratch free launch model too!!! I think ill keep the shell, box etc and try to find a motherboard.

    I have a similar problem. I do not think it is overheating and freezing occurs when removing the case. Yet it seems to me that this is a problem with the power supply. Sometimes freezing occurs when you insert a USB flash drive or a wireless joystick receiver ... I will keep looking.
    (Unfortunately I injured my left hand fingers on the woodworking machines, so troubleshooting is delayed at best for three weeks ...):livid:

    The homebrew USB device drivers don't seem to work well with this model (I always get weird freezes, even before my consoles became this bad). Sony did mention about a hardware bug in the USB controller, but didn't disclose the affected hardware revisions.

    Get well soon!

    I could not find a solution to the problem.(SCPH-10000 GH-001 Kisarazu-freezing)
    Has been fully dismantling the console, a thorough cleaning from dust, dirt and other things. I carefully looked over the board with a magnifying glass. Externally, all the details of the whole and undamaged. Traces of leaking capacitors or electrolytic I discovered. All suspected sites (solder cracks) I soldered.
    The power supply gives out 8.5 volts.
    The result is the same console freezes after 5-10 minutes of operation.
    The impression is that this is really overheating. I just do not understand what exactly is overheating. Perhaps thermally conductive pads have dried up and ceased to conduct heat, though outwardly they look normal.
    What will be the opinion that you can try to do?

    I think that turns off due to overheating "Graphics Synthesizer". Happens is that:
    After turning on the console, it is good for about 5-10 minutes. Then the screen freezes, music continues to operate.
    If you restart the console, it freezes almost immediately. If you leave her alone for about 1 hour, then all repeats (10 minutes of work and freezing). If the CPU is overheating protection, the works he (maybe I'm wrong). What are the views on this issue?

    Clock synthesizer chip for EE has gone bad. I've repaired a SCPH-15000 with that fault already (at the time I gave my previous posts I had not face such a fault yet).

    So when the clock signal deteriorates EE crashes and since IOP clock is derived from EE clock music slows down.

    Thanks for the answer! Can this be fixed? And how is it done?
    (I suspect that replacing the thermal spacers will not help.)
    What a chip marking where to look?

    Replacing the thermal spacers won't repair anything as the problem has really nothing to do with thermal issues.

    The clock synthesizer is the Texas Instruments chip marked "CKR61" right beside the solders for the PSU pin header, that on the "B" side of the board.

    Okay, thank you. I will try to find the chip and replace it. The results certainly let you know.
    (You don't know, by chance, a reliable supplier of chips?)
