My old blueberry iMac won't come on. I've changed power cords and tried different keyboards. No lights come on. Could it be the power supply? If so, where do I get one and how easy to install?

If you do not have a multimeter it will be very difficult for you to figure it out. If you do get back to me and I can help walk you through some steps. Otherwise, buy a new power supply, would not be worth paying someone to fix.

Buy a current tester( under a tender) and test if supply is going to pull cord (remove the 2screws on cover of pull cord. )Ifyou have power then it's you pull cord that needs replaced if not its mains fuse

You need to have a compatible keyboard. Since your Blueberry it so old, you might need to search around for a used one.

ebay often has these items for sale.

Check with Lexmark to see if there is a reset button for unit

ck drivers

This is called the blinking green light of death-----only one of two things can cause this problem.

First: remove front speaker grill (IT PULLS OFF) AND remove inspection plate behind it; look for the two bundles of wires coming down and to the right from the front keyboard of the set.

Unplug both plugs you find (different and marked so you cannot mix them up-----the idea is to take the front keyboard out of circuit-----set will still function with remote as receiver is behind front screen)

Try (after 70 seconds) to turn on with remote

If it comes on---defective reset button on front keyboard----use set only with remote or remove and remove actual reset switch---it is located behind and part of frame for screen----entire front screen would have to be removed to get at it.

Second: if disconnection of the front keyboard does not help, the DM unit is bad.

As you look from back of set it is large metal box at extreme left side.

The blinking light is the unit trying to "Boot" up-----these have a problem where caps and a few other parts in that unit fail-----kits on the net are available----Mitsubishi no longer sells or services these units but PTS Electronics does repair them.


Let me know if you have questions and try disconnection of the front keyboard FIRST.


REGARDS, SD TECH

there something wrong with hitachi neso cord, the one you used to connect from hitachi neso to your pc or imac, try to purchase new cord.

It would be very difficult to open up the imac to retrieve the disc as the CD drive is totally enclosed and would probably result in it not be functional after removing the disk. Have a look at the following article on the apple website
http://support.apple.com/kb/HT3007?viewlocale=en_US as it does indicate that the slot loading imac does have a hole for paperclip ejection. You could also try opening up disk utility and and clicking on the icon of your disk under the left hand column then go up to eject button and click eject. Hope this helps.

Chances are your logic board has failed, have seen it many times.

I'm thinking that your battery in the iMac is dead or very close to being dead. Or your power cord is no good anymore or your power supply is on the verge of being dead. Hope it helps.
