The red line on the board is on, after you start? Do not stay open too much machine as cover open you may burned out CPU (i had once).
If you need open cover workout you need put a 12 inch fan above cooler that emits air and put out (while only cover is open it works out when close you need fan opposite) if you look all things and found no error... check the cpu... i just got the same... cooling paste became aged and or other stuff. screw out cooler... and look white stribes arround cores. if any brownish or dark means burned out cpu... Other thing you may look... cables... and battery... you must look out cables... take off battery and wait 10 min and put back and PRAM reset... one stick ram... one hd. and no cd/dvd cabled. if those not work... look brownish white stribe arround core... if all things are good. it is nearly certain POWER.
