LCD monitor making crackling sounds and turning off

[Calum]

Hello all.
Recently the LCD monitor on the desktop PC has been having a few problems.
It started turning off for no reason, I discovered this was due to a loose power cord and just plugged it back in firmly.
Today, it happened again and I did the same.
However, it made a weird crackling sound and wouldn't stay on.
If I hold the cord in, it continues to make the noise and the power indicator LED goes on and off randomly.
It makes no difference if the monitor is on or off, it makes the noise if I move the cord.
I can guess this is electrical, but is there a way to know if the problem is with the cord or the monitor?
And is it fixable?
I don't fancy delivering the news that we need a new £100+ monitor.
The monitor is around 18 months old, AG Neovo F-17.
Thanks in advance for any help anyone can provide.
Calum.

Sounds to me like something inside (something electrical) is defective 

I don't think it's the cord as there is nothing in it to 'crackle'.  Connector, capacitor, resistor or something?  Bummer

So you reckon the monitor is bust?
*censored*.
Guess there's nothing I can do, monitors generally aren't user serviceable.
Thanks for your help.

Here's an update.
It was the F-417, not F-17.
And the monitor now works for no apparent reason.
I think I'll try and see what I can get from the warranty though, I don't want it to blow up or something.
