Black Display After CPU Fan Change

Customer changed fan himself on this laptop, screws are bent on the fan housing (assume he changed the blade part of the fan instead of the whole fan).

Powers up OK, apart from black screen.

- After removing the bottom housing, fan doesn't spin up at power up, only the LED on power button and keyboards light up. No indication of charging. After 20 secs fan spins at full load.

No bent pins on any of the sockets that could be causing a short circuit.

Have tried:

• Removing the battery and discharging any static
• Powering up with battery removed and only charger plugged in
• Removed RAM - No Sound from the speakers or and flashes indicating an error
• Unplugged ODD Board & Touchpad
• Changed RAM from bottom slot to top slot
