Re: MDD problem

[theleaddog]

I guess I didn't write well. There is the screw that goes through the
heatsink/cpu assembly and then there are several more screws that go
through the mobo...three IIRC. You'll notice there are a couple
chassis tangs at the edge of the board that it hooks or slides onto.
If you didn't remove the old thermal-conductive compound between the
heatsink and the cpu, you missed an opportunity. Pull up a flash file
and run it a few minutes to see how hot (Temperature Monitor.app) the
processors get. IF <143F, THEN okay, ELSE redo the compound.  :-)  The
dual processors are only useful if the application is written to use
them or you're multitasking. I think a flash video might use both
(Activity Monitor.app).

Re: MDD problem

[Jörg Duurkoop]

Hi Clark,

I don't know why. I like the old Adobe apps because I worked a lot
with them professionally. But since I installed CS2 on my Tiger disk I
could not start them any more using Classic. I could and can in
Panther though.  I don't like to start natively in OS9 although I had
to do that in order to use my SCSI-scanner and MOD drives. OSX also
"should" recognize my scanner via the Adaptec SCSI-card but VueScan
never finds a scanner.

Also when I had installed CS 2 on my MDD under Tiger I couldn't use
CS2 under Panther any more because I have only a license for one
computer. After dismounting my Tiger disks in Panther they worked fine
again. Now even with the Tiger disks mounted CS2 workes flawlessly in
Panther and all old Adobe apps, too (Photoshop 4, Illustrator 9,
Acrobat 4 - they are much faster under Classic in OSX than CS2 and
start in a flash).

At least after the recent swap my Logitech webcam is recognized in
Tiger too and its mic also as "unknown USB-device". And I found that
video performance is much better now. When I watch YouTube videos they
don't hiccup anymore but both processors appear to work at 100 percent
sometimes ;-)

My best regards to everyone here,

Jörg.

Why?  I have the set of Adobe apps that are Carbon and they are still  
working under Snow Leopard.

Re: MDD problem

[theleaddog]

The DP board will fit and work. Probably a good idea to push the PMU
button (not called CUDA in the MDD) once you get everything back
together in the event that the former owner had some hardware attached
which you don't. The replacement is fairly straight forward: unplug
all cables/wires from mobo, remove all PCI cards, unscrew the board,
and slide out. IIRC, there are only a few screws but I think you also
have to remove a screw that holds the processor/heat sink assembly to
the board. Take a look at the "new" board to see if one has been
removed when it was taken out of its case. Here's some further
detailed instructions for a 867 but it's the same case so should steer
you in the right direction:

Re: MDD problem

[Jörg Duurkoop]

Hi,

I just got another MDD 1.25 Ghz MDD with a dual processor. Can I put
the mainboard with the processors installed from the DP machine in my
single processor MDD 1.25? Should I press the CUDA before I swap the
boards? Anything else I should know before I do it? Is there a "how to
do" with pics like this one that shows the swapping procedure for the
PSU?

http://www.info.apple.com/nlnl/cip/pdf/n_g4mirror/fan_power_supply.pdf

I want to keep my old case as it looks like new, the DP Mac is not so
nice cosmetically and makes much more noise. Anything about the
firmware? Thanks for all hints. I want to be sure I won't botch this
job.

Best regards, Jörg.

Re: MDD problem

[Jörg Duurkoop]

Hi,

I didn't use the kb but the power button on the monitor which gave the
same result.

After resetting the PMU again I'm back at the same situation as before
the repair. A bong, all fans work, the red LED on the mobo is lit and
the disks spin up but only chatter for a short time, the monitor stays
dark. The processor on the graphic card gets warm.

After resetting the PMU the LED of the power button goes dark again
after releasing the button although there is the bong etc. The next
time I try to start after the reset the LED is extinguished for a
short period and comes back on after the bong.

I payed 110 euros with new quiet fans and  shipping back to my home.
The guy apparently also fixes mobos and will help me again. He told me
that my PSU was indeed defective.

Best regards, Jörg.

Re: MDD problem

[diane]

Did you try to start it with a keyboard instead of the power button? I've
heard that those buttons go bad sometimes.

Where did you send your PSU out to and how much did it cost? I had mine done
for $89 but it's a 12 month warranty.

Re: MDD problem

[Jörg Duurkoop]

Hi,

I had my PSU repaired (and upgraded as the guy that does it claims
that he replaces all the failure-prone parts too and gives a 3-year
warranty). Today I put it in my MDD, connected the big black connector
to the mainboard, connected two of my startup-disks, monitor, kb and
mouse. When I press the power switch on the front, only the LED of the
switch is alight and only as long as I press the switch.

Before I removed the PSU and sent it in for repair I still got a bong,
the red LED on the mainboard was lit and the disks at least tried to
start ...

So now either my mobo, CPU or both are bad? I'm very sad  :-(

Anybody has one last suggestion? I have very little money and know
nobody with a second MDD that I could abuse ...

Best regards, Jórg.

Had the same problem. Replaced the Front Panel Board (FPB), aka power
switch, *and* the Power Supply. Didn't help. Motherboard looked like
new -- no burn marks, no swollen capacitors, not visible cracked
traces. The red LED on the motherboard was firing. IIRC the HDs did
not spin up either. Ended up having to replace both the motherboard
and the CPU as neither tested good. When one went it took the other
along with it, I guess.

I don't know how far POST goes before it gives up but the power light
going out on release is serious. Perhaps bad RAM or a bad RAM socket
could hang the POST. You might try starting with just one stick of RAM
and try that individual stick in each socket. Check each stick this
way. Doubt that's it though. :-(

Unless you have a source for very inexpensive replacements, your money
might be better spent on an Intel Mac inasmuch as Apple and third
parties will soon drop all support on PPCs. If you go the repair route
be sure you get the right mobo. Check for exact Apple part numbers
here: http://tinyurl.com/2luemx. It might be wise to push the PMU
(power management unit) button when you mate a PCU to an unacquainted
mobo before startup.

Greetings

I know that a lot has been said about your problem, and the CUDA,
however may I suggest that you take a look at this WEB page:

Re: MDD problem

[yawg]

Hello,

I just tried to start my MDD another time, this time I held down the
start button for a longer time and lo and behold, at least I got the
same situation as before. The red LED on the mobo is lit.

The last thing I did was replace the single DIMM I left in and connect
another disk. Nothing looks burnt as far as I can see. Are there more
options before I send my PSU in for an overhaul?

Thanks again, Jörg.

Re: MDD problem

no... i dont think you burned out motherboard... CUDA is not burned out
motherboard. It is long story for my English.

Yes please test if you can your PSU before you got another one...

Re: MDD problem

[yawg]

Hi,

Thanks for your comments and help.

When I pressed the CUDA for a couple of times, about 10 to 20 seconds,
there was no battery installed.

I did this only after the normal CUDA procedure (5 sec. with battery)
didn't work.

How can I damage the motherboard without the battery? So it might be
wasted money if I send my PSU in for repair? I have to get another
MDD??

Best regards, Jörg.

Re: MDD problem

[Baha Ata]

infact you may finish battery but i did not get any bad things other than it
by pressing twice times to CUDA. Relax. It is not CUDA.

It might be CPU or PSU for my 2 cents..

I got same situation once i changed PSU and it not fixed... It was cpu...

Once i changed CPU but it was PSU.

I was lucky in second time because i had 2 MDD in my desk.

If you got a friend that have MDD.. You may test your CPU and PSU...

Sometimes it works... a little time... until CPU get too much hottet.. OR
PSU sometimes get work if some capaccitors halfly working... And it goes
away some times after...

My English is bad... or not enough to tell what i know.. but belive me i got
4 G4 and 2 of them MDD... and i know what i am saying.

NEVER push the CUDA more than ONE time for a few (± 6) seconds before a
restart!! Simply seen all the manuals and/or doc.'s I know. Pushing more
than once can destroy the whole CUDA-system!


To clarify...

Pressing the CUDA button reboots the Power 
Manager.  The PMU is the subprocessor that runs 
the whole motherboard.


There is no need to hold it down for ANY length of time.

Pressing it more than once, or even holding it 
down well, that means you're interrupting the 
boot cycle with yet-another boot cycle.  This can 
result in a screwed up PMU that will quickly 
drain the battery.


Press it ONCE and ONLY once.

Interesting. I had the same experience with a MDD DP 1.25 pre-2003
($1000 at the time). Replacing the PS didn't fix it. Took it to Apple
store. Genius said the processor was shot. Replaced the processor with
a good used one...no go. Figured when it went, it took out the mobo or
vice versa so I put in another used mobo with my old processor. Nada.
Replace processor with the good used one. Ta-da! I guess both items
were toasted. :-(

NEVER push the CUDA more than ONE time for a few (± 6) seconds before a
restart!! Simply seen all the manuals and/or doc.'s I know. Pushing more
than once can destroy the whole CUDA-system!
Besides that: In your case I strongly believe your PS is dead.

Nope, now you know it's a bad power supply. I now remember going though that 
hassle with a professors MDD about 6 months ago and got the identical results. 
Replacing the PS fixed all the problems.

Jörg,

You didn't "kill" anything, you isolated the problem so that it

Hy!

I feel sorry for your case. I know how it feels, when your beloved computer
seems dead. As John pointed out, CUDA is one of your last hopes.

This guy here http://forums.macrumors.com/showthread.php?t=135390 had a
problem with his memory - he inserted the memory backwards, thus he fried
the DIMM, but still they said that there is a hope in CUDA. If there was
hope in his case, why should be no hope in yours?

Besides, some 4 years ago, my Powerbook G3 went silent - the card holding
the power connector and rerouting power to the logic board was damaged. I
can still remember the scene - we, I and my friend, were trying to wake my
PB G3 from the dead by soldering the power card. As you know, when an old
powerbook boots, there is a long pause between the power-up and the chime,
and one of the few ways of knowing whether your computer actually started
was the presence of light on the keyboard or by measuring the electrical
parameters from the power card itself, by hand.
When we were about to give up, it finally booted. I cannot express my
feelings, that I felt at that time, after hours of hard work and trying.

Today, after 3 years, this Powerbook still runs. Therefore, there is some
hope for your powermac G4, so do not feel sad and do not give up to early!

With best wishes,
Matevž

Strip it down to basics.  One RAM DIMM, one hard drive, only the video card and 
monitor, no PCI cards, disconnect the optical drive cable, no Ethernet, FW or 
USB and see what it does.  If it still doesn't boot then try changing the RAM 
and HD.

Re: MDD problem

[yawg]

Hi,

Today I opened my MDD (1.25 GHz 2003 model) and it uses a Samsung PSU,
those PSUs seem to go at once and when they go the home fuse goes
also ...

All fans are running, the red LED on the mainboard is lit, I get a
bong, then the disks try to initialize but stop after a while. When I
put a CD in the DVD-drive that drive also spins up for a while.

But my monitors stay dark and the keyboard is not initialized - the
green LED on the capslock key stays dark. That's why I cannot use any
key-combos at startup, no PRAM reset or Alt to change my startup disk,
no shift to do a clean start. The mouse doesn't work either because
the drive should open when I start with the mouse pressed down. I
tried two keyboards.

One time the fans revved up after the bong for a second then back to
slow. I pulled all flatcables and power supplies to the drives and
reseated them. I have 3 start volumes, two Panther and one Tiger, I
normally run Tiger from a big SATA-drive that I use with a little SATA
to PATA adapter. I already removed the PRAM-battery for quite a while,
tried a new one, pulled all the RAM and cleaned and reseated it.

So I guess it's not the PSU's fault but what do I know? This is the
first Mac I cannot get to run again after a crash, it's very
frustrating.

Regards, Jörg.

Remove the PRAM battery and HDD's along with all the RAM including all cards. 
Unplug all cables. Spray clean all connections with a residue free contact 
cleaner. Wait a couple of hours then depress to CUDA switch for 15 seconds then 
reassemble with 1 stick of ram and restart.

Re: MDD problem

[Baha Ata]

The red line on the board is on, after you start?

Do not stay open too much machine as cover open you may burned out CPU (i
had once).

If you need open cover workout you need put a 12 inch fan above cooler that
emits air and put out (while only cover is open it works out when close you
need fan opposite)

if you look all things and found no error... check the cpu...

i just got the same... cooling paste became aged and or other stuff.

screw out cooler... and look white stribes arround cores. if any brownish or
dark means burned out cpu...

Other thing you may look...

cables...

and battery...

you must look out cables... take off battery and wait 10 min and put back
and PRAM reset... one stick ram... one hd. and no cd/dvd cabled.

if those not work... look brownish white stribe arround core...

if all things are good. it is nearly certain POWER.

The fact that you got a "bong" or chime was good. Did you try Safe  
boot holding the Shift key?



I couldn't even reset the PRAM, no second bong.


Might be a keyboard issue? Something could have happened the the  
keyboard when you were gone?


I tried reseating the 3 RAM-sticks, 2 512 and one 1024 MB, still no  
go.


If you get stuck, remove RAM to only one stick at a time.

I don't think it's likely this is a power supply problem.

You might try booting a install CD/DVD and running Disk Utility on the  
HD. You also might consider reinstalling the latest Combo Update if  
you have further problems. For certain do a Safe Boot holding the  
shift key because this will trash problematic cache files and get you  
a relatively clean start.

MDD problem

[yawg]

Hi,

Yesterday I came back home after 3 months abroad and started up my
MDD, it booted fine and I did some work and then played music from the
harddisk. Suddenly the music playback got stuck and the Mac froze. I
switched it off holding down the power button. When I started it again
I got the screen that tells you to restart in many languages (a stupid
thing - when you restart after seeing this screen the mac never
restarts, all you get is that same sceen again over and over).

But this time I didn't even get the "restart screen" again but only a
bong and then nothing, both my monitors stayed dark. I couldn't even
reset the PRAM, no second bong. Starting with the Alt button didn't
work either. After reading some old posts about the PRAM-battery
issues I bought a new battery today but still the same. I tried
reseating the 3 RAM-sticks, 2 512 and one 1024 MB, still no go.

What more can I try to get my Mac to work again? I am running mostly
Tiger and sometimes Panther if I want to use older Adobe apps. Would
this be a bad power supply?

I live in a relatively cool climate, the Netherlands, the fan of my
MDD 1.25 GHz (last model with FW 400) only speeds up sometimes when
it's very hot in the summer.

Thanks for your comments. Best regards, Jörg.
