My Toshiba Satellite Pro 4200 Series boot up and does nothing but display the picture of the half moon on the left and sun on the right, in between there is a blue bar, I believe this is the hibernation screen but no matter what I try it will always be the same everytime when I tried to switch on the laptop. Appreciate any of your advise. Thanks.

It sounds like the wrong display is active.
It may have been switched ot monitor or TV output.

I looked for the keys on Toshiba's site but right now the search feature for your notebook is down.

MANY notebooks use the same Fn+F4 or Alt+F4

If you have an owners manual, look up the correct key combination to restore the LCD output.

Had press Alt+F5 to toggle between ext monitor and even connected to ext monitor and it still display the same moon and sun when I switched on.

Well you're right the moon and sun is the sleep mode/wake up.

Here's some other info I found: " To cancel hibernation/suspend mode you need to press "backspace" a
few times(while booting the machine). It will cancel the hibernation/suspend
mode and give an error : Resume error. Press any key to continue. Press a
key and it will continue normally."

OR

Other tips included a second LITHIUM battery on the system board that brings the board in and out of sleep mode (I would doubt that one for this issue). or a faulty power supply.

I noticed there is a hibernation patch, I would try downloading the patch for your OS and seeing if you can run it from a command prompt.
