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.
.......

No video for a laptop is a COMMON problem and doesn't necessarily indicate the moard is not working.

Try connecting an external monitor to it.

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.

Actually, the original problem used to be the green power led light could continuously blink when the laptop is shutdown with battery plugged in, it could not start until after about 24 hours or even days, I took it to a technician to check it out.

I realized the motherboard was wet and the technician has used Petrol on it. Could this be the issue? Sometimes it displays colors of white, red, greem...e.t.c continuously.

The use of petrol or any other flammable liquid on electrical equipment is extremely hazardous. You should have smelt the odor of petrol.

A competent legitimate technician would NOT use anything that would leave a residue of anything on the mboard.

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

Have you tried connecting an external monitor to it ?
