PlayStation 2 MECHACON Adjustment Program (PMAP)

Has anyone documented where the test points are?

The service manual isnt that useful, when none of the test points or components are labelled on the motherboard.

Was going to give this a quick go, but dont really have time to hunt around for correct test points.

 

The service manual's diagram will show you where the points are. The points GND (JL609), TXD (JL610), RXD (JL611), +3.3V (JL613) and TEST_MODE (JL617) are very close to each other. In fact, they are neatly lined up in a line.
If the service manual does not indicate clearly where those points are, they are located on the side of the board that is above the expansion bay (where the service jig is inserted into). They're very close to (either around or on the reverse side of) the MECHACON.

For the SCPH-10000, I used the diagram for a GH-010. The pinout of the early MECHACON devices seemed to have remained the same until their replacement at the F-chassis (with the CXP103049).

 

The service manual for the machine I was working on didn't have anything very clear.

I did read this morning earlier in the thread that you mentioned it was accessed via the expansion bay, so was going to give it another look this evening - as I need to take the machine apart again to replace the USB ports.

It's an SCPH-50003 (GH-026)

 

Wow, your board looks... quite messed up. I take it back. @_@

Your points (JL610, JL611 and JL617) are very close to the upper left-hand corner of IC605 (CXD3098Q), on side B.

 

Found it, thanks for the pointers.

Will give it a go later

Ok, so got it hooked up and having a play with this.

I notice the "Display console information" option doesnt seem to know much about this board. Does this require similar info to the PS2IDENT app? as in, you need to add the information? or is it supposed to read it direct from the console?



Edit:

I also get "Unsupported chassis selected." when trying to adjust anything.

Edit edit:
Ah, looks like this board isnt support? Official tool tops out at 3900x?

 

A few early 5000x series are supported. I don't know at what GH number it stops though. Check my logs in this thread. I think I worked on one of the last supported models.

 

Yours must have been GH-023 then, mine is GH-026 and doesn't work

 

That looks very weird. What is the output of the "Show Ident Data" option in the main menu?

The last chassis supported is the I-chassis. The chassis does not always have a direct relationship with the mainboard model (i.e. you can have the same mainboard model across more than one chassis).

H and I-chassis consoles are supposed to have MD1.40. There is no MD1.35, unless it is something that SONY introduced after March 2003.
Although it is probably unlikely that you did not, did you ground your RS232C connection?

Anyway, most of the EEPROM options (except for the update) won't work on such a new console, due to the H and I-chassis having the EEPROM layout changed and the new SONY tool had no such feature. The elect and mechanism adjust controls could be copied because they exist.

 

Yes, I had it grounded.

I will get the info off the case later

Its an I Chassis

 

Thanks. Unfortunately, this either means that there are I-chassis sets that are not compatible with the tools that we have or there is somehow some communication problem. I do not know of any SONY adjustment tool that works with MD1.35, if there is really such a thing.

The MD version determines some things, like the EEPROM layout that the tool will use and whether certain commands are supported. So if that is either wrong or was not received correctly, the tool will not function properly.

 

Does your psident tool read the md version?

If so, may be worth using that to confirm its 1.35?

 

Unfortunately, no. This is information that is only available to the service tool.

But uhm, I'll PM you sometime later. I might have something else that you can try.

 

Is PMAP is based on Sony Serial Mecha tool ?

Can you provide a photo of tests points on your board ?

 

Yes, it was based on the EEPROM, ELECT and MECHA adjustment tools.

I don't really have diagrams because I only have a GH-001 for tests. You can get the location of the pins from the service manuals.
The earlier consoles have MECHACON devices that look similar to the CXP102064, so early service manuals (i.e. for GH-010) can help you with tracing the pins to their respective points.

 

I've tried using the tool with my GH-022 PS2, but unfortunately I can't even manage to start:
01. 0cfd READ MECHACON MD: 101 - rx-Command timed out
There was a problem communicating with the PlayStation 2 console.
Check the connections, press the RESET button and try again.

I'm using this RS232 to USB device: https://www.aliexpress.com/item/1pc...ter-STC-Replace-FT232-Module/32643852922.html
Since I couldn't find a service manual for GH-022, I've used the the one for GH-017 as reference, the test points seem to be at the same place.


There are LEDs for TXD and RXD on the adapter. TXD flashes once when I select an option in PMAP, so it shouldn't be a driver problem.
What am I doing wrong?

/EDIT
Nevermind, I didn't realize that you have to connect RXD (PS2) to TXD (USB adapter) and vice versa. It's working now

I've tried the Automatic ELECT adjustment now, but I only get to the DVD-SL stage. I insert the DVD, the laser clicks once or twice and I'm back at the menu with the following message:
Electric Circuit Adjustment
This tool allows you to re-calibrate the electric circuit of the CD/DVD drive.
You need to do this if you:
1. Change/remove the OPtical (OP) block
2. Change/remove the spindle motor
3. Change the MECHACON
Warning! This process MAY damage the laser if the wrong type of disc is used!

Continue with automatic ELECT adjustment? [y/n]y
Insert test CD and press ENTER
Insert test DVD-SL and press ENTER

Thanks. There was a problem with the CD/DVD detect ratio calculation code.

Changelog for v1.1.1:

• Corrected formula for calculating the CD/DVD disc detection ratio.

Any plan to expand this project to another console drives like Saturn ? Some model have also a software calibration.

 

No. There is only me working on this and the SONY tools are already very massive.
I'm pretty sure that there is no universal tool for adjusting all consoles, so the Saturn consoles are better off with having a specific tool written for them.

 

Hello to everyone,

I´ve been collecting some PS2 models SCPH-30004R, all with the 400C lens burnt.
I have 3 mod chiped motherboads for these consoles: 1 is GH015 (V5 with DMS4 Pro) and the other 2 are GH015 (V6 with Duo2 SE)
After replacement of the lasers, two of the GH 015 (1 V5 and 1 V6) motherboards are having weird different behaviours from the third one:

When powering on the console, the disc makes 5 clicks and keeps showing "reading disc..." on the screen for exactly 1 minute. After that the disc starts to spin and reads just fine every format. even Dual layer DVD´s. So I assume is not a laser problem anymore.
When reading CD´s (psone/audio) it takes about 3 minutes to load. This hapens on 2 of the boards.
The third board is fine reading and detecting CDs/DVDs right after pressing the power button, but it has the bad GPU or something else because the graphics are all messed up.

But regarding the other two motherboards, especially the one with DMS4, I would love to make it work again as it was new, because it has sentimental value: it was a gift and it was my first PS2. I would really love to solve this problem, and ive lost years of my life searching and investigating and spent a lot of money sending it to shops for repair without anyone knowing how to solve its problem.
I only found one video on youtube with the same situation as me:


Is this PMAP adjustment program the solution to my problem? Does anyone know what might be wrong with my PS2?
If needed I can make a video with sound and a better explanation.

Sorry for the long post but i´ve searched and tryed everything I know, and I´m sad because I didn´t found a solution.
Thanks everyone.

 

These tools can help but probably not at the stage this problem is at.
It seems the laser doesn't detect the reflection of the disc until the software tries a different strategy.
The wait time with "Reading disc.." is very unusual. It could be related to the modchip in that case.

Normally, the console starts looking for a DVD first, then for a CD, then DVD again.
Can you see what the laser is doing right after inserting the disc? (Never look into the laser directly!)
