v13 MI Install Issues –
OK, so I'm trying to get this Matrix Infinity (orange dot) installed on a v13. I've done all the wires except SX (only required for PS1 backups, correct?) and they all seem OK. The machine boots/reboots fine but only ever shows a jumpy black screen (dark grey'ish lines running along the screen making it jumpy.) It never shows the boot logo or anything, just black w/ dark lines. I originally had the R & V points mixed up, but fixed that, though it didn't help.
Also, I used this diagram V13 MI Diagram assuming that since it was the same pic on the MI website for both 12/13 it would work. Perhaps there are slight differences? I know I've got the right points, but perhaps some aren't soldered well enough? What should I be checking for.
I'd post a pic but unfortunately I don't have a digital camera.
Also my 3.3v point might be bad, when the power is on I get 3.49 on the side I'm supposed to have the PWR wire, and 1.9 on the other side, normal? Is there anywhere I can get a list of voltages I should be getting for v13?
Thanks in advance
Sounds like your in PAL mode instead of NTSC. If you ever tried to play a PAL DVD in an NTSC player you will know what I mean.. If this is your problem, hold Circle + Triangle on boot and set the video mode to the right one and see if that works. Defaultly it should be color, but yours might have been set to PAL somehow. Set it for your region and save it.
If thats not what you mean you probably have some bios wires confused or crossed. Also I would check grounding, use a short as possible (2-3CM long) twisted 30AWG and solder it from the gnd point on the chip directly to the chassis ground (copper bar running around the board) just use a key or knife to scratch off that flux crap so the solder sticks.
Holding Circle + Triangle does nothing. I've tried moving the GND point so it's about 1 cm away, but that didn't work, I'm also using 24G solid wire for GND/PWR if that makes a difference. Perhaps I'll try to resolder all my bios points tonight, is there a diagram for which points on the board corrispond to which points on the chip? I tested the resistance of all my wires and they seem fine, also checked for continuity between bios points, and that's all fine as well.
Just to confirm, SX isn't required?
And nobody knows where I can get a list of voltages for each point?
BTW, will the machine boot up without the laser block attached? Just wondering, since it would make testing faster.
Now, after taking the chip out the problem still exists, so obviously I've blown something or bridged something, any ideas?
I've checked the board pretty well and see no visible issues, perhaps a blown fuse, but I don't know where to look and what I'm looking for in terms of voltage etc..
OK, so after checking all the fuses (used a v12 diagram, assume it's the same for v13) it would seem that my PS14 fuse is blown. I don't get continuity, but I do get a resistance of about 1.53 kOHM. Assuming that this is the same as a v12 I should get full continuity and no resistance, correct? If that's the case then I now have to look at replacing this fuse....
Also, could this cause a chip to die? If so which chip? If any how would I go about testing the chip(s)?
OK, so for anyone having similar issues I replaced the PS14 fuse which died with a glass 2.0A fuse (had to run some wires around to the top of the board so I'd have enough room to fit the fuse.) Resoldered all the wires, double checked all my connections, and viola, worked like a charm. So, I'm thinking I blew the fuse because I had the R/V points mixed up on my first install, so let that be a lesson to others, check all points/connections with a multimeter before powering up, lol.
