yes it a chip for ps2. i preffer hardware modding but i cant find a diagram..

 

thanx dude

 

thnx very much. ill try this. without a laser protection diodes

 

That's right it was fixed with v13+. The comsoft v4 fix was also pretty good. Does anyone know if any of these modern Matrix Infinity clones (e.g. Modbo 5.0) fixed the one game that broke with the 1.93 firmware "Hot Shots Tennis" -freezing on start screen/graphic distortion?

 

Just a reminder, the Diode "fix" also didn't fix anything. The root of the problem was the mechacon crash that happend, when bad media was used.
If anyone of you guys deals with such a console, please use the Matrix PIC fix and nothing else.

EDIT: Yeah, basically what @Armadillo said

 

yes. I quit diode fix' ..

 

ok. i will change them. but if the wires was not good , how the chip can start?! (matrix logo) not enough power to operate?

 

PS2 chips can just be fussy.

Matrix logo is provided by the points going to the bios iirc. That part, not too fussy and will generally always show, unless the install is completely wrong and broken.

Part that boots backups can be really fussy and refuse to play nice for a number of reasons. If changing 3.3V/GND to thicker gauge stuff does nothing for booting backups, then you want to be looking at A G H I B. Shorten them if you can, try not to have them cross over each other too much etc.

 

ok.. i came back with same problem. i checked and rechecked wires 3 times. (i rewired conections) I changed power wires... same problem. just infinity logo and nothing more. no boot no nothing... when i press circle shoud enter in chip boot menu no?

i've seen in a post that 3.3v was tooked from other side, more near the cpu. But i cant see very clear from where it is conected. I think is conected in that resistor. i leave the pic in here...

the guy who belong this picture had same problem. infinity logo and nothing more. He missed to conect H solder. Than said:

1st post : I found a PAL Matrix Infinity V5 diagram that instructed not to add G at all so I tried removing it last night but that didn't help. I'll try connecting H. Will probably redo all the connections on that side of the chip too, I'll try not routing the cables under chip legs too.//"

2nd post: Seems like that was the solution, connecting both G and H. How frustrating! Oh well, glad it is fixed now.
After that works fine.
