After replacement drives are running, but still no boot.

Texte:

my initial problem was that the MBP wasn't booting. infact it wasn't doing much but flashing the white LED angrily then going black. I replaced the RAM, let it sit for long times, did magical boot incatations with my fingers, tried different power supplies, etc.

I ordered and replaced the MBP. Now at least I get the beginning of a normal boot sequence but still no chime. I can hear the drive being engaged and the CDROM ( which has a boot disk as well ) spinning up, and the white LED remains on.

the display is black. a working external display also does not show any image other than an "incompatible video mode" message.

I have tried different media but I do not get to the 'choose drive' option.

ideas?
