Question about Computers & Internet
It does sound like a back light issue. Not under warranty?
The fact that it does light up suggests it may be a heat induced fault? May be just a simple dry solder joint. Although you cannot rule out the CCFL (Cold Cathode fluorescent lamps) being faulty either. A quick check with a meter may tell you if it is the light source or the driver cct that is at fault.
If its the lamps, salvaging some from another LCD may be a good cheap altenative.
Usually there is a simple fault (failed FET/Transistor) causing these problems so if you are good with a soldering iron and can work thru the cct to locate the offending FET/transistor it will be a relatively cheap and easy fix.
