White Screen on iMac A1224 - EMC2210
My wife's iMac 20" Core 2 Duo (A1224 - EMC2210) started to present a strange problem. She was working normally when the screen suddenly turned white. She tried turn off the iMac and could not. We took all his cables, turned off the power cord and waited for about 30 minutes. Then I reconnected everything and iMac turn on normally. It worked for about 15/20 minutes and then the white screen again. The iMac is fully locked, does not turn off, does not respond to any command, nothing ... That's when I decided to open it and see the LEDs indicators.
At first the iMac turn on normally and about 15/20 minutes of use... again white screen, but before that I realized that, the LEDs all went out and started to light in sequence (same as the boot, but the iMac was not restarting), the 3 first LEDs are on, and the last one off. And the screen went white.
So what can be ... the LCD ??? The Inveter ??? Or something worse ?!
