In need of some help

[legioss]

I had finished my install of of an Ultra 2 on Friday ( V1 with 020 bios and a GH 005 MB) and everything worked fine. I took it apart again to hot glue the wires down like a good little installer and the x wire came flying off! Maird!

So I resolder the x wire and now nothing boots. A few more attempts and redo the B to I wires and still the same thing. However, If I boot a PS1 game first, then I can subsequently load originals. Just no backups. Once I try and boot a backup, then nothing works and I have to go throught the whole process again.

Now, out of desperation I pull the power wire and try booting orignals. That works. Put the power back and redo the B though I points again. Same thing. Out of desperation, I solder the x point to the via (charlie_ps2 forgive me) and loe and behold, things are looking up. Originals and PS1 backups boot fine, and SSX tricky boots fine, but stuntman will not. If I boot a PS1 game, stuntman will boot. It sometimes thinks it is a PS1 game, which is weird.

I am fresh out of ides. I have resoldered every single point, save the SCEX and Y point as I do not want to go through removing the power daughter board again. I have read throught the installation troubleshooting FAQ and could repeat it in my sleep.

I have one theory. The surface mount component, which I could not figure out what type it is, must be slightly hosed. There is enough current for the system to function, but with the wire attached, there is too much draw and the x point on the Ultra 2 is not getting the right signal. However on the via, the system is receiving the proper current.

Could someone who has a GH005 do a continuity test on this component and also measure the resistance of the chip? I am getting 10.15 Kohms, which I think is way too high. With the wire on the smd, I get 14.6 Kohms. With the wire on the via, I get 10.15 Kohms.

Any help would be greatly appreciated.

P.S. I have done numerous searches and could not find any related data. Oh and BTW the PS1 boot is similar to the Magic 2.

Thanks.

Thanks Guichi for the point about some contact cleaner.

You wouldn't by chance have any clue what type of smb that puppy is? Resistor, diode, zener diode, capacitor?

Gee, I had hoped for a response from charlie_ps2. Or even LOD. But I guess they are a little busy right now.

Well I have just done some more testing, and the longer the machine is on, the worse it gets. I am thingking it is a heat issue. The ground is attached to one of the four small point grounds on the MB. I am going to move the ground to a larger pad and see what happens. Also, it would seem that the Fan is not pushing as hard as it should.

Man, this is becoming a real pain!

If you are running your PS2 without its covers and without its metal cage and/or without the conducting rubber from various chips to the cage then that Could account for the problems.

Well it turned out to be a few things.

First, we have the infamous memory card issue. I have not taken the machine apart to test the fuse yet, but here is rundown. Some games booted with the memory card in and others did not. The after a while the machine would get a little hotter and then I would get red screens. This I attributed to the fact that with the memory card inserted, there was more current draw on the system. The more current draw, the hotter things get. The hotter things get, the lower the resitance of componenets gets ( or higher, I can never remember). This then causes bad voltages and the chip goes south.

I powered down and let it cool. Then brought it back up with no memory card and no issues until I tried other media brands that just so happened to be less than clean. So then I figured out the focus was to blame for some disks not booting. Clean them up and no problem. Execpt for one lowly kodak disk that just keeps giving me problems. Power off, let is sit for 30 seconds and then power up, good focus and game boots.

Now I am just trying to figure out if I need a cap on the s line or not.

I have photos of the install for everyones enjoyment.
