This is with a PAL v5, if it makes any difference.
P.S. i used the alt clk point, using thicker wire (same as for + and -) and it works fine, no noise
the ground point is correct the guy does not know what he is talking about you simply scrape away the green enammel until copper shows in that location shown on the v5 diagrams and solder to it simple as that or use the ground point on the messiah 1 diagrams.
Yah, I went and checked out the magic2 diagram that I used and it was the same point.
Someone I sold a messiah 2 to says his chips fried and that 3.3V and Ground points are shorted out somehow on the messiah 2. Now I doubt that this is true (because it would blow a fuse in the ps2 for one, and he has said that backing out of the install revives the ps2) Just trouble shooting. Hopefully its just a chip that need the tracks cut on the back or something. We'll see.
also it does not aways blow fuses when this happens.
Ok holdn a sec here
now he said they short out when he gave only his messiah 2 chip. What exactly are you refering to when you say grounding plate. Do you mean the metal frame of the ps2? or is there a "grounding plate" on the M2 itself?
yeah i mean the frame that goes on the the ps2 mother board its called a grounding plate when you screw this down it shorts out the messiah 2 depending on where you place it.
from what he described on the phone. They two points are shorted out when the messiah is disconnected from anything (exsept the ohm meter of course). Even if the chip was fried this would not be a symptom. there is either user error (more likely) and there is not a short or the short is cause by some solder floating around or there is a major manufacturing error (very unlikely)
I was originally hoping that this track cutting may fix the problem.
That now seems unlikely
by the sound of it it wants chucking its an installer error a small blob of solder could have dropped on the main ic shorting power and ground they are all manufactured the same so this isnt the problem if you tell him to check for that wait a second i know what he could have done tell him to check the cut track if he has cut the track its possible a shard from the cut track is touching ground this is the most probable cause its easy done as the track you cut is power and ground surrounds this track if that sorts the power and ground shorting and the chip still does not work hes blown the chip or its an install error.
hasnt cut the track yet. I'll have the chip back on sat. I'll perform all of my tests then. It is easyer to just test it all myself insted of trying to explain to him what I want. Then not knowing if he's done anything right.
Thanks alot for your help EnTiTy
