I have a weird setup. It consists of a screen-broken and water-damaged keyboard laptop hooked up to a Monitor and a external keyboard.
My problem started 2 days ago when i was playing a full screen game, the game froze and so i pressed ALT + ESC to get to the desktop but nothing was happening, i repeatedly pressed it and still nothing so i started spamming the CTRL + ALT + DEL key and then the ESC key. Still nothing until finally the screen instantly went from the fullscreen game, to the desktop, to the CTRL+ALT+DEL screen and finally back to the fullscreen game until the screen went fully blank.
(Blank = black screen, absolutely nothing on)
so, it was stuck on this screen until i powered of the laptop by holding the power key.

Anyway, now every single time i'm on it, the monitor screen instantly blanks out every like 7 seconds and i have to turn off only the monitor(Laptop excluded) and back on before it blanks out again X seconds later. The power button still stays green suggesting it is connected.
I've also noticed that the longer i turn of the Monitor, the longer it will stay on before turning of.
For example, when i turn it off when i go bed and wake up the next morning to turn it back on, it will take like 1 hour to black out and every single time i turn it off and on again X seconds seems to decrease until it blanks out every 7 seconds again.
I've also ruled out that the Laptop, VGA and power cord is causing this since it also happens when not connected to the Laptop. I've replaced the VGA cord and power cord aswell.
i suspect it could be a blown capacitor but i dont wanna open up my monitor and break it. I'm also only 15 so i doubt i could buy all the tools to replace the capacitor. Or maybe its something else.

I'm running a Windows 8-64bit Packard bell Easynote TE11HC.
V2.01 Bios
and a Intel(R) Celeron(R) CPU B830 @ ~1.80Ghz (2 CPUs)
It contains 6GB Ram and 500GB Hard drive
the display uses Intel(R) HD graphics.
and is integrated.

Do you supposed i save up money, buy a soldering iron and replace a capacitor IF blown since i haven't checked... or maybe its something else.
 
Solution
Hi, it's not worth buying a soldering iron if you do not know which component is faulty. Any component on the motherboard may be defective within your monitor for that kind of problem.
