2009 / Dead Mac Puzzle Problem

« on: November 02, 2009, 04:37:02 AM »

I have solved the 7200 problem, rather daft really, the contrast and brightness were turned down on the monitor
The Performa has just blown it's fuse in the PSU. I took the old Quadra 630 case apart, I do love the way everything just seems slide out with Apple form factors, unfortunately the PSU was the last thing to be removed. I was quite surprised at it, it really is an archaic bit of kit. I'll post some pics if anyone is interested. One of the links you gave me Paddy was very useful as it contained an article about the Quadra 630 form factor

Regarding plug boards and plug sockets, I use a plug tester. It looks like an ordinary three pin plug but with different lights that allow you diagnose any faults within the plug socket, such as if the wires are the wrong way round, lose, if the earth isn't correctly grounded or any other faults. I find it invaluable, especially before I'm about to plug in a new wide screen HD TV, or other expensive device.

2009 / Dead Mac Puzzle Problem

I recently did install a new PRAM battery in the Performa, also in the 5500 (from adopt a mac), I did try another just to check but still nothing. As for the 7200, it's still the same. I have a lot of 7200 spares, so I'll do a parts swap in the morning. I did remove the hard drive from the 6320 and installed it in the 5500, everything on there seems to be okay, started up first time. I checked the HDD with Norton as well as drive setup and disk first aid, they all said it was clear.

Could I be right in thinking the PSU might of gone in the Performa?

Off topic,
Thank you for your help, I appreciate it.
Also why does it say I'm a child poster? I thought that it might be because I have a low post count, however others don't seem to have this.

As if the G4 Quicksilver wasn't enough, another strange event has happened. I have three older Macs plugged in to one extension board, 6320, 7200/90, and a 5500/275 Director's Edition. I went to start the three of them up this morning and only the 5500 booted, the 7200 chimed but did not produce anything on the monitor, not even a signal. The most upsetting for me was my Performa 6320, (my beloved childhood computer, a present when I was nine, I'm now twenty-two) it was completely dead, nothing, no chime, no light. I pursued the usual procedure of PRAM, unnecessary component removal, the same symptoms prevail. Have I suffered a power surge?

Just an update, Newark do have a UK site, it's called Farnell, not obvious in anyway. The UK site is more expensive, so much so, that if you ordered more than a few items it would be cheaper to pay the $25 handling fee. However due to another event I have decided to break up the G4 QS for parts, sad I know, but it will be used to upgrade and extend the life of others.

I'm running the G4 AGP Graphics at the moment and just completely taken the G4QS out of service. I'll ring Minebea Co. Ltd. which is their UK branch and ask for a UK distributor because they don't list any on their UK site.

I did come across the Newark site but as I'm in the UK they charge a $25 (£15) handling fee for international orders under $100.
I read alot of articles on xlr8yourmac but their mainly to do with fan noise, something I simply cured by using anti-vibration matting, I tend to find G4s and also G3 B&Ws vibrate in their metal case.
So all I need to do is find a UK distributor of NMB fans.

Also the current model of CPU fan in my QS is 2410ml-04w-b47.

A few more hours (sigh) of hard searching eventually led to the NMB website, which contained all the specifications for the Minebea brand fans, everything from airflow to noise levels. It is even possible to replace the standard 2410ml-04w-b47 with a higher air flow 2410ml-04w-b60 and still be with in the PSU load.

For future reference here is the Minebea site

The CPU fan in my 733mhz G4QS failed. I'm now trying to find a replacement, Akasa and Thermaltake make PC case fans of the same dimensions. I was perhaps hoping someone might know, or be able to point me in the direction of the original Apple fan specifications, such as did it have a thermal sensor or not?
