Has anybody ever had this problem (that I have) after installing a modchip ?
So install went fine (this was about the 100-150th install that I did) I always recheck every single wire/connection for about 3-4 times,before powering up the PS2. Chip is a Matrix MXL. PS2 turns on, eject works. Inserting a PS2 cd/dvd the disk spins a bit then slows, then the browser. No matter if the disk's a backup or original. Removed the chip, the same symphtom. I tested the BA5815, it seems ok, as reading pin 8 doesn't give zero. (so it's not ground) I tested the motherbard *all fuses are ok*, no solder bridges, no bios problem. What the hell can it be ?
I have here 3 other PS2's that have the same problem (all seemed to be clear installs) I contacted the local Sony service and they said that the drive/opu is bad. I doubt it as the drives perform very well with other mb's. But these motherboards do not work with any drive at all. I first thought that the 5V chips caused the troubles. (as two were killed by a NH3, and one by a Magic 3.1) but now as the Matrix killed this machine (which was brand new, and was tested for 1 hour before the install, and worked just fine...) I have no clue what's going on, and how to repair these PS2's. If anybody can suggest me anything that would be cool.
thanks and regards, Stephen
ok, you say reading the BA5815 doesn't give zero, so its blown (if ithink what you meant was that it gave you a reading, but did you check the BA66 chip?
Hey buddy ... You do this ... See if the point where you usually connect the 5V for the Magic 3 chips has really 5v. for this you can power the board with just the reset cable and PSU connected.
If there's no 5V there, the disc won't spin as it powers the low tension part of the BA6664 chip.
If you get 0V at that point, check PS13. (GH-019 and GH-022 boards.) It's a resistor like component with a white H in it. It's VERY small. Test if it's open. It should measure 0 ohm. If it's not 0 it's blown. Change it for a 0 ohm resistor or a same rating fuse if you can find one to buy.
I dunn, i think hes bluffing, he has 3 wrecked PS2s, and it is his 100th-150th install? Sounds kinda odd to me, but check the BA66
Guys, yes maybe that sounds strange but I did 100-150 installs up till now. I have never had any problems, except a few that were cold solder points and so on. This one I described above happened 4 times up til now. I can live with it, not that a big heartache, but I thought someone knows what causes this. I don't want to cheat with stickers, and playing sily games like that, but would like to know what causes this problem I described. It happened 4 times to me, and I'd like to know what I should do to repair these boards/or what I should do not to cause the same problem IF it is me (my install) that's the problem at all. That is why I said that I already did 100-150 installs, so it was not my first try, and not my second one. I know that BAD chips can cause problems, that is why I asked. And I am sure many people have problems with their installs, even they don't tell so. I do, as there's nothing I want to hide. I can fail, as anybody else can, sorry if that sounds like a bluff. I asked what the problem might be, and what could go wrong. Tell me if I installed a wrong wire, and I will see. (thought I did not) But telling me that I am just bluffing is not really that I was seeking for.
So let me be totally techincal: the threads I read up till now said that when someone read zero at the BA5815's pin 8 then it's blown. It does NOT give zero. And checked a working PS2 and it's also not zero... (so I'm pretty sure that the BA 5815 is GOOD)
i_olivera: I checked that fuse, it's ok, the reading is 0 so it's not blown.
I will check all reading around the two BA ic's and will see. I assume nobody is expecting the local sony serivce being correct saying that the opu is bad, as this can easily be traced (if anyone really wants to trace it anyway) that this problem has nothing to do to the opu...
PS: by the way: can a bad modchip cause this ? (just as said, one NH3 killed TWO ps2's in ONE hour, I doubt that I miss installed one chip in two machines two times in one hour.... had no mood to install that in a third machine, but if anyone wants to give it a go, I gladly will post the chip for him for free...)
