x200s Post, Screen Buzzes, Then Screen Goes Blank
x200s Post, Screen Buzzes, Then Screen Goes Blank
I picked up a fault X200s for $20 with the hope of fixing it. The issue is when turned on, it posts for a few seconds, I hear a buzz and then the screen goes blank.
Checked with a external screen and it seems to be fine, so it looks to be screen related.
Wondering if it is likely to be the digital inverter or a blown fuse, which i read someone it could be.
Have done a some work on Thinkpads previously but never changed a screen or inverter.
Any help would be appreciated.

Is that a CCFL backlight?
It sounds more like a broken tube.

Thanks RealBlackStuff.
Sounds as if I need to investigate further.

Re: x200s Post, Screen Buzzes, Then Screen Goes Blank
Is there a way to determine that the CCFL backlight or if it has a broken tube and if so how difficult would it be to fix?
The screen flashes up for a bit but then it flashes off after hearing a hissing sound.

Put a flashlight to the display and see if an image appears, but dark. If so, probably the CCFL
