Hello,
I have an Inspiron 1720 (17" screen). A while back, the display started to flicker occasionally, and from my experience with Dell laptops I suspected that the inverter was on the way out. Sure enough, eventually the display just went black, although some parts of the screen (mainly white or light-coloured ones) were still faintly visible. The laptop goes fine on an external monitor.
Suspecting the inverter, I purchased a replacement, and I installed it, only to find that the problem was persisting. I am baffled as to why this is the case as I was about 98% sure that the inverter was the the problem, from experiences with other dell laptops.
Of course, there is always the possibility that although the inverter I purchased was brand new, that it was faulty. I will try to find out if this is the case. In the meantime, however, are there any suggestions as to what might be the problem, and how I might go about fixing it?
Thanks in advance for any help.
