Have you, or is it possible someone else who had access to this computer...
- dropped it, or dropped anything on it, or otherwise exposed it to a physical jolt ?
- spilled liquid on it, or sprayed it with liquid, or exposed it to liquid such as rain ?

Since the video last worked properly all the time, has there been a power failure event that happened while the AC adapter was plugged in ?

Those things are the most frequent reasons something inside the laptop has been damaged.

If you connect an external monitor to it, you will probably find there is never a problem with the display on that - usually there is nothing wrong with the video adapter or the specific software Windows is using for it. In that case the problem is probably caused by the display assembly having been damaged, or the wiring between it and the video adapter having been damaged. .

Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.

See response 1:

DO NOT plug in or unplug a monitor's video cable into / from a video port while the computer is running. Doing so can damage the monitor's circuits and/or the video adapter's circuits.

Some laptops will display on an external monitor without you having to do anything.

If you get no video on an external monitor, some laptops have a key combo that you must press to toggle the display to external video only / built in display video only / sometimes both - see the Owner's or User's manual for the model.
