First of all, this is a hardware problem. Second of all, the inverter is fine; it worked fine on the cracked LCD.

This is the situation: I replaced an LCD with the same exact model except the model number had a -L2 after it as opposed to -L1 on the original. The original and replacement were both Samsungs and I assume that the -L2 denoted that the replacement is the glossy version. Everything works fine except that it appears dark.

So I do the obvious and hit the "FN" + "brighness up" keys. This is what happens with every key stroke: the brightness goes up, then down, then up, then, even lower, then up. It seems that it is adjusting randomly between levels - none of which are bright enough. I did some googling and found that many people have had this type of problem after replacing LCDs; but i never found a solution.

Any ideas?

My theory is that the -L2 Samsung has a more powerful lammp to compensate for the darkening caused by the glossy coating and the inverter on the Dell can't handle the powerful lamp.

Your help is greatly appreciated.
