I have vertical lines showing up over the signal source from my home theater projector. I changed the lamp module but no luck. Gone through all adjustments, Bad card maybe? The unit is a Toshiba TDP-MT800

Does it look like interference? I had this little bar fridge that caused vertical lines on my projector and it took me forever to figure out what caused it. Then one day I had to unplug the fridge, and voilà, it was gone. Electrical interference will cause that.
