No, they do not need to be returned in a whole state, as we would just break them down.
Having said that, if the stand or any other part has a use to a project, it can be kept too.
The 19 was the one I had the most hope for, as it would flash on, but then go dark...
The 17 has no picture, but it may just be a backlight, so maybe see if the 19's is the same size (I doubt it, but still)
If it is the backlight, give me a bulb make and model, I can try the online place I picked up on for my old 15 dell last year.
Thanks for taking the time to look at these, I hope we can find a couple of working ones out of the group.
