Does your monitor display anything when it is on, but no signal is
coming? Most do show something (e.g. VGA1:No Input).
Disconnect the laptop and see.

There might be bad connection, most probably on your laptop VGA
connector. Try moving  the cable at the laptop side and see if it
connects/disconnects.

Most VGA connectors these days are soldered directly on motherboard
(cheaper) than properly fixed to the chassis and connected with
flexible cables to the motherboard and with some stress they become
unsoldered and even break the motherboard by lifting the solder pads.

If this is your problem and you have warranty - they'll fix it. If you
don't have warranty, you may try it yourself with appropriate
soldering tools&skillz.
