Here are some things you can try (at your own risk)
1. Remove the power adapter, battery and CMOS battery. Use a screwdriver to bridge the two small pins where the CMOS battery plugs into the motherboard. Replace everything and try to boot. If you get a 5 beep code then switch it off and reboot again.
2. Check all the LCD cables. You may have crimped one or not connected it properly when putting the machine back together.
