screen turn on and off when I touch the laptop lifebook s751

screen turning on and off when i touch the laptop mostly on the body, everything is working ok even when i touch the screen ,, so i dont think so its about screen.. i tried to open it up but all wires or sockets where in the right place.. so i wonder what it might be.. should i just change the main board?

what you think guys?

thanks

i checked everything, i disassembled down to the main board, everything looks very ok. ports are solid, but when i push some where around to the CPU fan area picture will gone, and i have to shout down and turn on again. i tested the main board alone to be sure nothing is shorting between sink and main board, but still same result..

any idea?

Thanks
