the only time I've had this problem it was because I flashed an incompatible hboot... had to drop a PB31IMG.zip on sd card and shoot in the dark to install it. If you haven't done anything with the Hboot, then IDK. try dropping Hboot .92, 1.02, or 1.07 on sd card as PB31IMG.zip... when you boot, hold down vol - and power on. be patient, because you can't see....wait about 30 seconds and push vol+ to install the parsed hboot and then wait about 30 seconds more and push vol+ to reboot..hold down the vol- to hopefullly get into a visible bootloader. Other than that...maybe looking at a hardware problem...open up all the motherboard covers and see if anything is fried...Good luck! and be gentle with the ribbons if you tear it down!
