My iMac DV 450+ can't startup. When startup, there will be 3 beep sound instead of startup chime. Then the power button will flash 3 times repeatedly. I checked Apport Support web page and found the answer as below:
"The power on self-test resides in the ROM of the computer. This test runs whenever the computer is turned on after being fully shut down (the power-on self-test does not run if the computer is only restarted).
If a fault is detected during the test, you will not hear a normal startup chime. Instead, the system will beep as explained below. If you experience one of these beeps, you may call your Apple Authorized Service Provider for additional troubleshooting assistance.
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length."
Just want to know if anyone knows what does "no good banks" mean? Does it relate to motherboard issue? I think it's a serious problem. Just want to know how much will it cost if I send it to Apple to repair?
If anyone has experienced the above, kindly share and advise your solutions.
Million thanks in advance.
