Fan full speed after booting and no video signal
After pushing the power button of my mac mini, the cooling fan goes to max speed and does not put out any video signal. The Power LED is on and white.
- I removed the power cord and cleaned the fan and the inner of the mac -> no change
- I tried to remove both RAM sticks and boot -> mac beeps once every couple seconds and the fan seems to be on normal speed. But still no video Signal.
- I tried to boot with only 1 RAM stick -> Still fan ramps up to the max and no video signal.
Does anyone have an idea what I could troubleshoot next?
I am thankful for any ideas and comments.
