Q. Will replacing a cracked digitizer screen also fix dead pixels?
The digitizer is solely responsible for converting your touch inputs to a digital signal understood by your computer.
Typically, there are three layers involved with capacitive touch screen technology, the highest layer is normally a thin sheet of glass. This is often attached to the digitizer, which, for your machine, looks like this:
The final part is the LCD panel, which actually displays the image through the digitizer and glass.
As such, replacing the digitizer will have no effect on the LCD image.
Q. I was wondering if I replaced the digitizer, what the odds are the pixels might come back to life via 'massage' or one of those software programs out there.
A. Perhaps, but as your screen has taken physical damage, very unlikely.
There are software utilities that will cycle all pixels on the screen through full colour ranges, which can on occasion resolve the issue. There are also methods of trying to massage the screen to fix the stuck pixels. However, in your scenario where the screen has taken physical damage and an entire row is damaged, it's very unlikely this will be a temporary state with an easy fix. As such, a replacement of the LCD unit is likely your only resolution for this.
