i love my bondi blue, but i fear that her time has come. it won't power up anymore. when i power it on via the keyboard power switch, the monitor clicks on and the power button on the front turns orange, but then nothing else happens. no picture on the monitor, and the button never turns green.
any suggestions? could it just be a fuse or something?
You've obviously got power because the LED is lit - can you hear the fan running as well? Your symptoms point to a video problem.
Since it's a Bondi are you still running pre-OS X? OS 8 or 9? If so first reset the PRAM - start up and hold down Command+Option+P+R - and see if that helps. If not you'll have to open her up. If you haven't done this before there's a walk-through
here. If you're not confident enough to do this then you'll either have to get her looked at by an Apple engineer, or say goodbye to her.
If you do want to take her apart the next step is to reset the CUDA chip. To do this you'll need to remove the logic board, so read to the end of sub-section 2 in the Slot-loading iMac section at the above link.
Once you have the logic board out the CUDA is a small button next to the processor. You should be able to see it in the attached picture. Press the button firmly, and once only. Put her back together and try again.
If you still have no luck the next step is to reset the logic board. The correct procedure to do this is as follows:
1. Unplug the computer
2. Disconnect the cable that runs from the power supply to the power filter board on the bottom of the logic board assembley.
3. Press the power on button on the front of the unit.
4. Remove the logic board.
5. Remove the battery from the logic board.
6. Wait at least 10 minutes before replacing the battery.
7. Make sure the battery is installed in the correct +/- direction.
8. Reassemble the computer and test the unit.
If it still isn't working the next steps are to remove and reset the RAM, then remove and reset the processor. If it still doesn't work you need to start replacing parts, so it may not be worth the expense.
Both the RAM and the processor are under the chrome shield to the left of the CUDA in the picture. Remove the shield and you'll see the processor and the RAM as in
this picture. Take them out carefully and put them back in carefully.
Good luck.
