Packard Bell EasyNote TJ71 Crashes when tilted

Hi, i have been given the above laptop to look at. Basically when the laptop boots if you pick it up and tile it the screen changes colour and displays a blue boxed effect and then the whole laptop crashes leaving the frozen image on the screen. You have to then hold the button in to hard re-boot it. If you try to reboot straight away it will power on but nothing will display, also no hdd activity. You have to leave for a few minutes and then try again.

I have stripped most of the laptop down to try to identify the problem. I have ruled out the switch and i think i have ruled out the screen. If i apply pressure to the right hand side hinge with a screwdriver the screen will change colour showing the blue boxes. I also noticed this if i apply a little pressure to where the connectors are for the screen on the motherboard. Before i carry on stripping it back does anyone have any ideas as to what is causing this?

    As for the screen changing colors I've seen this before as a result of a failing inverter or connection between the inverter and the motherboard. (Side note: Lenovo T410's are known for this.)
    And normally when a system is tilted (Or moved) and it shuts down, freezes, etc. that is due to a loose component such as the CPU, RAM, etc. You stated you've checked the RAM but how about the CPU? I'm assuming that everything else is normal where cooling is concerned (CPU fan, etc.).

    I haven't checked the CPU. I will look at this tonight and let you know. Thanks

    It was the CPU that needed reseating. Thanks for the help
