View Full Version : 3.45V alt on v7?
Are there any other alternates for the power wire on a version 7 motherboard for a messiah install. I know of the main one and the alt that are stated in the install diagram. I also know that I could use the 3.45V for the color fix, but I would like to leave this open for the fix. I am trying to change my magic chip to a messiah and the first two power spots just aren't working. I had gotten them to stick just a little but the wire pulled off. Tried soldering again and the connection gets worse and worse. Please help, thank you.

use 30awg kynar for the power u should have np then
i shouldnt post that here but messiah2 runs on such low voltage it will cause np
flux the resistor ,put blob of solder paste on wire,bring wire to the resistor,touch solder paste with solder iron,should work does here even with thicker wire
Managed to find some kynar wire. Looks good. More easily stripped then enameled and stay in the position you put it better too. Just out of curiosity, what do you use to strip your wire. I have been using a set of nail clippers. That was a real pain with the enameled wire.
Another question also. I have two different messiah chips, some from you and Charlie_PS2, and one That I overpaid for from another place. The one from the other place is version 1.08, yours are 1.22. Whats the difference?

I myself haven't tried this one (http://199.185.130.13/theclub/foundmy/device/fm-v7-gh-019-main.jpg), but I should work.
Just out of curiosity, what do you use to strip your wire.
When I installed mine, I used a lighter. Headed up the end of the wire and with a paper towel pulled off the melted shielding before it hardened again.
Thanks for the alternate points kooldraco. Unfortunatly it was no help. I have tried 2 SCex points in combination with three 3.45volt points and it still will not work. I did get the power wire on the original point. I had to buy some new flux and just load the point with it, and it eventually took. Pisses me off! I had been waiting for a DMS3 but heard they had this problem, then that problem, and another problem that their working on, so I said F it, I'll just throw a messiah in there. Now after two days I've gotten no where. So now to go pull out all the wires and start over again after work on wednesday.

Stripping wires....i my self used a razer blade. I layed the wire flat on a cd case. Then rested the razer on it, in a chopping position. Then with my left finger, rolled the wire, and the razer about an inch. Then pulled the cut plastic off.
Too much force with razer will cut it off. But after about 5 wires...i had it down good.
If you had 2 needels, same size as wire. You could put them on both sides of wire while you cut with blade...as a safety for the wire. (i have non myself...)

wire stripers
the kind with a spring and wheel adjustment once set corret just lock the wheel off
v1.22 covers more versions of ps2 and uses a better code

I found the odd problem with using AWG30 kynar wire for the 3.45 connection ( thread marked 'suspect Messiah 2' being one of them.
Occasionally I reassemble and find that the messiah 2 seems 2 be dead.
Have now started to use thin multi strand wire for the 3.45v connection and ground as this is easy to tin and still small enough to get on the 3.45v solder point and haven't had a problem since. Also use stacks of liquid flux on point and adjust solder Iron up another 25 degrees if having trouble getting wire to take.
As for stripping wire, used to use my old chunky soldering iron to melt the insulation back but now use thermal strippers. super quick and perfect every time.
Regards.........
OK, I just tried the install for the third time, still no luck. I have tried 24 and 30 gauge for the power and ground. Tried 3 power spots, 2 ground spots, and 2 scex spots, and 2 messiah chips. All solder points have looked excellent each time, all wires are hooked up to the correct places, and it still acts as if there is no chip. WTF?
The only thing I can suggest is to use slightly thicker multistranded wire for the power and ground, Then flash up the PS2 in bits i.e just motherboard, power supply board and dvd drive on an insulated surface and get a multimeter across the 3.45 volt and ground connections on the messiah 2 and check that the voltage is actually getting there.
It's a bit tricky getting it plugged up together without a shield around the board or a case but can be done ( I've done it).
You'll need lots of none conductive stuff to prop things on, U should just need motherboard, power board, DVD Drive and reset/eject button assembly.
Good luck.
I have noticed that the number on the board is GH-022. Where would I find the BIOS numbers? I have looked on the chip but can't seem to find anything that matches the three digit format used.
Ah, u thinkin that it the diode problem?
I think the number u after is the bottom right hand number on the chip, 0***.
Wot version messiah 2 is it?
If it recent then should be 1.22 or 1.3 and they should be okay.
Actually I wasn't thinking of a dioade problem. What problem are you speaking of? I have Messiah v1.22 that I got off, well you should know who.
Cool.... I was thinkin of diode problem.
Did u try monitoring voltage across messiah 2 3.45v and ground?
No I have not tried to check the voltage yet. I am currently out of town. When I get back it is the first thing I am going to do. The problem with the diode hat you are speaking of. Is it the one adressed by the PCB fix?
Checked for power and power was OK. Uninstalled the chip for the third time, and now I am just thinking. Checked the BIOS legs for bridges and balls again. Its all ok. The only other thing that I can think of, if you guys think that it is at all possible, is that I was reading another post on ps2newz and one guy had a similar problem on a version 4. It was suggested to him to check the clk connection. He posted that his problem was solved but never posted his solution. Does anybody have any clue what is going on here? I sure don't. I am losing my mind. Almost ready to go buy another ps2 and try and see if that one works.
R u using a single wire for the clock wire or r u using the 'twisted pair' method?
This seems kinda odd though. Clock wire connection would have to be non existent for chip to be dead.
Usually the clock wire just suffers from EMC problems and needs a close by ground plane to cut town crosstalk voltage.
well, if the juice is there then it ain't ur problem, scex and clock wires r the next natural suspects.

agrred u should use 24swg multicore for the power
but headley was saying he had problems soldering it to the resistor(kept falling off)
this why i recomended 30 awg kynar as it will solder to the resistor without any probs
on a v7 30awg kynar shouldnt caus a problem
on older ps2 yes u need 24swg for sure

do ps1 backups boot?
if u sure your power is good
clock is to correct point(as otto says sound problems due to bad clock but not nothing at all)
if nothing boots backups ps2 and ps1 then i say check double check u soldered to the correct bios points as the messiah2 wont intiate unless the bios connections are correct
I cannot get any backups to boot at all. I have gotten very used to the sounds my PS2 makes when booting backups and it is missing to clicks off the end.I always install the clock wire as a twisted pair, why not do things right the first time. Seemed like a very good connection everytime. I usually check every connection by giving it a good tug. If I can't pull hard of nearly pick the mobo off the counter with it I resolder it. I am sure that the bios points are to the correct place, and I have tried two SCex points. I found a power point that was on a pad so I am sure I have a good connection there, I am now using the 24awg. I really have no clue. I have done this install, on this ps2, three times already. Each time I have been very careful, cut new wires, label them all, go throughthe install guide point by point. Only other thing I am going to try next time is the alternate clock point. This is about the only wire that could cause the problem that I have not tried an alternate for.
Thanks for the help. I'll keep you all posted.

pad for power on v7 ,u got a picture this is most likely your problem, no power
my reason for this is if theres a good pad to solder the power to i think it would be in the diagram it would make install alot easier
24swg to 3.45 isnt the easiest of jobs

solder your power to the origanal 3.45 in the diagram,u wont be able to tug it with thick wire it will fall off
to test place your meter on the alternat power piont in he official diagram,place other on the m2 power pad u soon see if u got a good connection or not from your meter without having to tug it ,then glue it in position
also make sure scex is to diagram piont aswell(is ps1 boot we know m2 has power)
to me your m2 has no power,either power or ground ,or bios as m2 needs this to initiate itself
For the pic of the power pad go back to kooldraco's post the the previous page. It has power, I checked it myself with the volt meter 3.473 volts. As I stated earlier i have tried the two power points listwed in the install several time. I had even moved the ground to the outer rim of the mobo to make sure it was a good connection.Got some things to do today, going to try another install tonight. This makes number four, for this machine.

i stand corrected pad measures good,
u have no other messiah2 u could swap it with to test,if chip is at fault we replace it if its one of ours which i guess it is
I have already tried a second chip, no luck. I am really puzzled by this one. :confused: :confused: :confused:

just a quick thought sorry if u answered this already
gho22 i seen u post
bios 080 or 090(hehe i read through thread again bios is located on top of the chip which u solder mnop qtuvrw points 2)
if its 090 u got a v8 u need 1.30 firmware for v8
although im sure 1.22a would boot cdr and fail on dvdr only
I take this to mean that the bios is 070, but not sure so here's everytning.
S023933
MX23L4800YC-10G
2002 SCEI
D 119 050 M48
B 10 070
2G398800
That is everything written on the bios chip. It had occured to me to check out the v8 possibility but I got the PS2 in the US about 2 months ago, so it didn't seem likely, but I am from a small town where weird things happen.

20-03-2003, 09:53
its a v7 o70 and 080 are classed as v7
090 is classed as v8

I can vouch that Headly's install is top notch.....I am willing to bet that it's a weird compatibility issue......:confused:
Yeah if this foerth install don't work tonight we are going to get those fireworks off wirenut and send that f**ker to the moon!:D :rolleyes: :eek:

That, or we can always do our top secret 'swap trick';)
Do you think we could make a rectangular cannon made specificaly to send PS2s into orbit?

OK, this is the situation. I have tried the fourth install of the Messiah chip in my PS2. This time with a third chip. Got the install done and I have to say that it was such a beutiful job that it almost made me cry. Hook up my PS2 to the TV and nothing. Power light comes on to standby, push it, and the eject button just does one quick blink and nothing. Try turning it on with eject and the same effect. I ahd the same problems yesterday when a fuse blew and also when two of my BIOS wires were touching. First I check the BIos its all good. Then check all the fuses twice. All good. Try again, same effect. I then unhooked every BIOS wire. Same effect. I then unhook the power wire, same effect. I go back to inspect the BIOS legs and see nothing but figure I'll touch them up anyway. Try it without BIOS or power connect, still nothing. So then I get ready to unistall the chip again. Put it all back together without the chip and low and behold it works. What in the hell is going on here. No wires were touching anything that they were not supposed to. BIOS and power unplugged and it was f**ked up. take out the chip and its ok. Do I live in some mystery spot where v7 PS2 do not work with Messiah chips , I am going mad over this. Please give me any info you can think of on my situation. Thanks for all thye help.

IMO (which isin't worth a whole hell of alot over here), it's definitly a chip problem. The system worked fine with a Magic chip(best chip out there IMO but i know this board's leaders support Messiah). As Headly also stated the system works fine with no chip also. He's tried 3 diffrent Messiah chips(all versions 1.22), so its hard to beleive they are all defective, which points towards a compatibility issue, but I would think the makers/installers of the chip would of found that out by now. If the chips are indeed defective, they are doing something funky(shorting out or something) with the points they are connected to. I'm intrested to see what the problem is.

if there were no bridges,ps2 not work with m2 installed,but works when removed,then something is shorting when m2 is installed,on the heat plate maybe
were is the m2 positioned ?as per official diagram?
or as per magic3,1 if this is your position i guess the chip (red component,diode)is shorting against the heat removing plate when u reassemble
3 chips all do same i doubt its the chip,altough if diode shorts as i suggested above its possible the chips have blown now
The two previous messiah did not do the same. The other two had no affetc at all. Originals booted fine, no backups booted. This chip did seem to short something out. I did have the chip located as per the diagram and covered with tape. When the BIOS and power wire were removed they also were covered.

Sounds like someone has a refund coming on some chips;) Or at least exchanges...
OK, this is the latest developement in my story. I said to hell with putting a messiah in this PS2 and decided to put my magic back in. When I replaced the Magic chip it had the same affect as the irst two messiah I had tried. Went back in checked the bios clip and it was good. Then I retrimmed all the ends of the wires and did another complete reinstall of the magic. Still the same thing. What on earth could I have done to make a PS2 reject all chips? Don't let Sony get ahold of this one.
Now that its out the disc doesn't spin. The laser earches but no spinning. I am freaking out!!!

swap on bad chips is np,if it was the chips ;)
to me u have bridge,or possible solder ball behing the legs
cd/dvd drive problems means it could be a-i as well cd/dvd controller points
b and c bridged??

does the tray eject if not possibly ba58 chip , check the fuse
dont forget the obvius reset powr lead,it can be tested with a meter the wires appear seperate at either end of the silver foil
8x magnifying glass check whole board long job but it must be done,solder balls ,wire clippings are found in the most strangest places,both sides
I doubt that it is the CD\DVD controller as this is aon the backside and I cleaned it up real good with desoldering braid adter the unistall. Cleaned up all the points where the magic was connected very well. Only thing that I expected was the bios. After I romoved that damn bios clip I had noticed that i mashed solder all over the place. Did my best to clean it up but it is hard to see. I only have a 2x lens, have to wait for a friend to get home and bring his up. I checked out b and c they are good.
swap on bad chips is np
What does this mean?
nevermind. Got ti as soon as I posted. Thought you were talking about going back to the magic, sorry
Yup I've given up on it. Only good thing about it is that I am negotiating selling the laser to Freakzilla. He has recently sent his PS2 to Bill who says that he needs a new laser. Good news is that mine happens to have about 30 hours on it. So I am going to see if we can work some thing out.
