A friend of mine in AU just asked me about

"Tektronix THS720 handheld digital oscilloscope. As you can see in the
attached photo, the LCD module is starting to go bad. Research indicates
that the problem is likely due to the polarizer films deteriorating, and
they can be replaced"

Anyone have any other suggestions? The image in the photo showed a clear
image, just fading on part of it. I suggested the inverter be checked,
but am no expert on these units.

Thanks!

Any way to post a pic John? I have that model and would be interested in seeing the issue.
