I have a 50001 PS2 that I got used. When I first got it I never noticed that the vibration function wasn't working on any ports so upon googling around I saw some people mention the PS9 fuse being a source of problems and proceeded to disassemble my system to take a look. It wasn't till I read a bit more on a few sites, after I had it apart, that this was likely not the case. The PS9 fuse appears to be the 5VDC fuse for the system which feeds the HDD as well and seeing as I use my HDD exclusively and with no problems I doubted it was the fuse. (More likely its the busted controller port, which works input-wise, just not the vibration)
Anyway, upon putting it back together and plugging it in it boots but I have a weird problem. The audio is messed up, on start the menu show up sounds are fine but if you scroll through the selections on the OSD the sound will echo and then get staticky and sometimes freeze the audio. Everything seems fine visually, though I think the HDD support isn't working. Does this sound like a particular problem that is easily remedied? Maybe I put it back together slightly wrong? Screwed up something that should be grounded but isn't?
At the moment I'm assuming static discharge shot the board, but I thought I would check anyway.
EDIT: Oh for the record, its not modded nor ever has been attempted.
Not sure about the audio problem but my version 7 Ps2 Scph-39001 had no viberation either and the fuse that controls that is the PS7. I just solder it with a single strand of wire to jump the fuse and I got viberation back.
Its probably not recommend to do since now theres no safety fuse to blow but im fine with it. I heard the fuse they used wasnt enough amps anyway, dont know if thats true or not.
If you're having vibration problems in your PS2, check the output pin of TA7808F. TA7808F is a 3 terminal voltage regulator, with an input of 12V and an output of 8V. The 8V output is used for the vibration feature of your controller. (CON_+8V in the schematic)
If you see 8V as your output, then that means the fuses are very likely good.
If you don't see 8V as your output on TA7808F, then check the continuity on PS009 and PS011 with a multimeter. The fuse numbers might be different on the SCPH-50001, but it's the same idea.
Here's a picture from the SCPH-30001 schematic:
For GH-023 and 026 it's PS07.
Please pay close attention on the IC-LINK fuses numbers, but consider this important piece of advice:
PART NUMBERS do vary from board type to another so DO NOT RELY completely on "guides" you find on the Internet. :cool:
Good luck with your repair. :)
