This is how the screen was from the get go. In the right lighting, you could navigate the OS.

After replacing the two capacitors on the inverter board with some good used caps, I was able to get an image, but nothing that could be readable with a dark background or a lot of black displayed on the screen.

This is with a light background so I could see what I was doing.

Changing the background to something darker, or the default grey, resulted in a darkened image, and a lot of bright stripes from the corners of windows.

Even with the brighter background, anything black on the screen leaves a shadow line from top to bottom, which you can somewhat see in this picture.
