Sound like TFT screen h/w related.... I got a laptop that does something
similar with an external monitor IF the screen cable gets kinked or is
not connected properly. Check all the cables and connectors and vertical
lines or a somewhat 'green' image cleans up. I'd take a look at the P3
connections and cables.

Hello all, I am trying to figure out why our P3 panadapter sometimes but not
always shows a group of vertical green stripes that cover about 1/6 of the
width of the screen. These stripes are not related to RF frequency because if
I switch bands they remain in the same location. If I remain on one band and
twirl the VFO knob, real radio signals move into the green stripes but the
stripes themselves are immobile.
Sometimes these are not there at all. Sometimes they are near the left of the
screen, more often toward the middle.
Wayne gave some instructions for investigating this on PX3,but this is P3.
Any ideas?
Am I correct that these cannot be related to real RF interference due to the
above facts? Wouldn't real RF be frequency-related? We do sometimes get RF
interference that shows as periodic narrow lines on the waterfall, but these
wide stripes are different.
THANKS!
