I found this thread while I was looking for information on these discs. Here is a link to the ISO dump of one of the discs. You can take a closer look at the disc contents if you would like. https://vimm.net/vault/74324 Hi, thank you for the link but this is a test disc for the PlayStation 2 :) I'm...

Yeah, my idea was to dump this bios and a make a comparison from a good one. I've an XGECU eeprom programmer, but I can't find a guide how to dump it :/

Thank you, mate !!!
You know a method to dump the BIOS chip with a programmer?

GUYS... PROBLEM SOLVED!

IT WAS THE BIOS!

I replaced the BIOS with another from an SCPH-1002 and it works (SCPH-1000 use a 40 pin BIOS package). Probably it remains stucked because the code was incompleted or faulty during the SCEX check.

It's working flawlessy!

Hi guys... just a little update. I've replaced the CPU with a compatible one (picked from an old SCPH-1002 - 208pin) and... NOTHING. ALWAYS STUCK. I really don't know what a kind of problem have this PlayStation... but, I don't get it T-T Maybe the holy Trimesh can help me :crying :crying :crying :c...

Hello, thank you for the response. I've replaced all the CD servo's IC. Nothing changed... As you said, the CPU is bad. Because, if you force an STR playback, there a lot of square artifacts (bad MDEC decompression module). So... for me, it's unrepairable. SCPH-1000 have a different CPU from a 1001 ...

Hi fellas. How are you? :D :D I've an SCPH-1000 (serial 6323386 - CPU 14th week of '95) with an strange problem (I've repaired a lot of PS -- but this one is tough). Laser replaced (KSM-440AAM --> KSM-440BAM), excellent RF signal (no jitter, stable RF envelope and 1.2v p-p), very fast reading, but w...

For my experience... I use Silicon Oil (F72) for motor sled/motor spindle), and lithium grease for the gears. Never an issue.

Hello. Maybe you broke the RF Amplifier (on the SCPH-9002 should be the CXA2575N aka A2575N). LDON (APC ON) is present (watch the laser radiation). Did you have a broken PSone? They have the same RF Amplifier. Try to replace that IC. Oh btw, did you test another laser? About Q701. That regulator is ...

Hello, I think I've found (finally) the pot value

F.BIAS (14) = 10Kohm
F.GAIN (54) = 50Kohm

Let me know if works

Hi guys, i really love the music of GT1 and i want to extract the .SEQ of this game and convert on .PSF :D ! Hi, I know this request is quite old now but better late than never. I've been working on that game among other ones last month and have a WIP Minipsf set for both the Japanese and internati...

If you want, the user manual of SCPH-1000 is available on archive.org.

Enjoy

You're welcome !

I think you can...

CXD1199Q and CXD1815Q have the same package and same number of pin (100 QFP)

Hello!
I think the laser intensity is too high (like shadow says on the latest message).

Try to reduce the current for the laser diode (trimmer on the flat cable) and after that, check the F.BIAS.

CXD2922/CXD2925 broken (SPU).

Replace with another one.

I'm glad that method work !
Enjoy your PS !

Okay, I've watched the video. The SPU sounds okay and... probably the issued is CD-XA encoder (I think is partially damaged). Because the data are readed correctly, but no the XA/STR file type. No audio means -- no decoding. So, make a try -- Replace the CXD1815Q with a working one and see If there ...

Hello! Do you have a video about this issue? No music you say? TEKKEN 2 / TEKKEN 3 use .XA format. Maybe the CXD1815 is K.O? (CD-XA encoder) Do yourself this test: 1) Play music from CD player and check if is working (CD-DA test). 2) Play game with .XA format based (Tekken 3, Ace Combat 3 or Tenchu)...

Broken CD-XA decoder. License.dat didn't read correctly by this one. Replace CXD1815 with another.
