Fixing a Monitor; need some assistance

[Argelfraster]

I got this 24" monitor from a friend and am trying to fix it. It turns on and runs for about 10-15 seconds and then the screen goes out, but the status LED on the front says its getting a signal.
I opened up the monitor to examine the boards inside and found two things that looked out of the usual:

The first looks like a blown cap.
The second is probably nothing, but i may clean it up just to be safe.
Could the blown cap be the issue? or might the backlight be broken?
Thanks in advance

Blown caps are usually the issue in monitors that won't stay on. I just got a monitor and fixed it for $8 via cap replacement.

Upon further investigation I found that that component is not a capacitor but rather a posistor.
Does anyone know where I can get a Posistor? I can't seem to find them

Posistor is a brand, look for a PTC Thermistor (Positive Temperature Coefficient thermistor).

I'm not sure of the resistance of it, but this may be a starting point as to where to get one.
