2000 imac

[abidjan]

I have a 2000 imac that sort of works, but not really. I spoke to 2 repair shops and got the same idea of what is wrong: the analog board, which contains the power supply and video display. One rep said that b/c it's a slot loading imac, there's no fan.

The problem: it will power up, but seems to overheat after a few hours. THe light on the front starts to blick and fade. Finally, it won't even power up.

My question: I opened up the back of the machine and find that although it's very small and not much is readily accessible, if the part that needs to be replaced is one of the 2 boards that come in and out easily, I can do that myself. If not, it's probably not worth repairing, financially. Could someone help me confirm that if the problem is as the repair guys told me, that I could do this myself and save the cost of a diagnosis and labor?

I'm not a computer person, but if it's a simple mechanical type repair (not requiring any computer knowledge really) I should be able to do it. Right? Thanks very much, Abidjan.

Hoenstly, without the machien in front of me I can't say for certain what the problem might be. And I can't tell you if swapping a card is going to help. Certainly swapping the video card won't help.

This my be caused by low voltage to your machine. If the available voltage is too low, the machine's powersupply must work too hard to supply the board and drive volts.


Find a tester for AC voltage, see if your wall socket is supplying less that 110. If it is low, get a voltage stabilizer, also known as a line conditioner. I have a Tripp Lite LC-1800 here. It will deliver higher and cleaner voltage to the apliance.

This may or may not be the problem. Also, be sure there is no dust clogs in the vent holes, top and bottom. Clean them out with a vacuum cleaner and a brush attatchment.
