Messiah 2 not reading –
I've read all the docs about the Messiah 2 install and lasers etc. But I'm unsure how to proceed with this. (PS2 v4 no gap)
I had a qualified soldering bod to install the Messiah2. I installed it all, and it worked great for about 10 mins, but then stopped reading the disc mid game.
Did a reboot - can't find disc.
Try original GT3 - part loads then stops.
So I dimantled my PS2 again and checked all cables etc, take off reseat.
Checked for shorts on the case. There was the possibility that the Messiah 2 touched the metal by the red fuse looking thing, so I shielded this..
Still no boot.
So - I take apart again and check what's actually going on. The laser flicks on and off a bit and tries to read, kind of ticking like it's trying to re-read over the first track.... does this is on all discs.
I cleaned the laser thinking it may be dirty..no joy.
I've never had read problems before my install with my old USB Neo, so it seems a big coincidence that the laser goes bad right now. Do modchip installs often produce laser problems?
Should I really have to recalibrate my laser as the Messiah docs suggest? I could perhaps understand having to do this if just DVD's were not working - but is this a possible fix if nothing is working??
Can anyone suggest what's gone wrong?
Many thanks for any help.
I've just moved the pot a little clock wise (less than 1/4 turn) and this has made the laser on all the time, but still doing the same.
Think I'll wait until I can get a multimeter in my hands before I go any further..
Me too.. –
Different mod but same problem.
Mine on this occacion is magic homebrew, been working for 2 weeks then turned on one day to give the same symptoms as yours.
The console has not been moved from its usual position from the day it was chipped.
I do not think that this is down to it being a homebrew mod itself as it is working fine in other versions and posts from different chip installs have given the same symptoms.
Mod has been removed to leave the same symptoms, no disk is detected in the drive and if X is pressed at the Browser then after a while it just says ERROR READING DISK.
I have checked points A-I for splashes/bridges and solder balls but they are clean.
I am now looking for a way to test the cd/dvd controller without going through the normal boot sequence to see if this chip has been damaged.
Including my own this is the third post I have seen here regarding consoles being left with the ERROR READING DISK problem with no significant course of action to test for why this may have happened, except for wire check/remove mod.
This is my spare(old v3(020)) test machine so it is not a great loss but would like to be able to eliminate the modding process alone from being the cause.
I get the hint
I'll get my man to check it out properly and report back ASAP.
I give up.
After spending hours looking at the damn thing it still does the same. Checked and double checked everything.
This morning it booted GT3 original - then booted nothing again!
There may have been a short on the Messiah board as it was a little high to the casing, we insulated this.
We set the dvd laser pot to 1100 ohms.
All points were checked for shorts, no solder balls found.
The only item I wasn't sure about - but my installer said was ok is the voltage point. On the v4 board docs it clearly points to the edge of a component (3.5V NTSC point). He has put the point on the circle pads to the right of this component as he believes this is also a valid voltage source. Is this correct? We cannot power up and check this as the psu is in the way unless we rig up some kind of power cable.
All heat xfer blocks are very secure.
It simply tries to read the disc 1/8th turn then stops. All discs.
Am I left with the last solution of removing the mod?
Does it look like my laser is dead? (but I would have assumed part reads, or just read originals or cd's or something).
I have emailed Carl in Morecambe with regards to looking at the ps2 for me. It's very hard when you do not have any spare parts!
Sounds the same –
Although we are talking about different mods, the symptoms are the same.
I have already backed out of the install removing all wires and checking, checking and checking again for splashes/balls/bridges, there are NONE!!
The install was clean from the beginning which is why is worked flawlessly for 2 weeks.
The laser spin sounds the same as mine also, 2 or 3 1/8 turns (pulses) then spins up to a faster speed. I compared this to (my problem one is a v3) a v4(gap) and v5 (30003r), they both spin slowly but constantly from the start then spin up to full speed.
As soon as I can lay my hands on a v3 i'll swap the laser unit to try to eliminate the 2 controller chips on the laser assembly although they both had the heat tranfere rubber squarely seated across them and fixed into position.
If I make any headway i'll let you know.
I wouldn't use the NTSC fix point for your power. The install Guide on the official Messiah 2 site, www.messiah2.com shows the point near the disk drive (labelled 3.3v). It is important to use the officially recommend point because it is validated not to spike out of Actel's range during the boot process. You kind of ignored that recommendation in my earlier post but appear to have recognised the point just now.
Other 3.x points are not guaranteed and have been measured to spike 3.6v at the very point that the Actel chip needs to recognise what's going on.
I don't know if that's your problem but that should in any case be the rule.
If your installer used a via for the power point (you know my view on the use of vias), then he might have done the same for the CD/DVD Controller points. Again the official install guide is cleaer on this matter. Solder to the CD/DVD Controller legs.
Finally, the Â¼ turn thing. The FAQ articles make it clear that this occurs when the laser can't find the data groove. It tries a couple of times and then gives up. There are three plausible possible causes:
- It really cant find the groove and everything else is OK (incl. lens is clean, azimuth correct, disk clean, etc.) . This is unlikely to be the cause as it plays the game occasionally.
- There is a cable problem. The firmware looks for the groove because of the activer control lines, but cannot report the result because of some aberration in the data cable (orange). It might be a small kink - not properly connected anything.
- There is a mis-install in the BIOS or CD/DVD Controller that prevents data from reaching the PS2. Now I find this hard to accept because the Messiah2 isn't interested in anything until the groove has been found and it now needs to boot. But solder balls can definitely interfere with the groove seeking report and this is a possibility. It may not be affecting the pins to which you soldered but may be elsewhere.
So good luck with Carl.
DOH! 3.3v coming up then.
So is there a possible fried meesiah 2 with too many volts?
Definately all other points on the legs. That was the only via which I picked him up on.
I'll mess with the cable again later..
Thanks for your time and effort helping me out here..
