My iScan line doubler is not working so I connected the DVD player directly to the S-Video input on the back of the VPH-D50Q projector. The image shows but with huge scan lines. Im not sure if when I purchased the projector if I also purchased the exbds10 internal doubler. After intering the service mode I cannot find the IDTV option, but if I select one of the switcher #1-9 on the remote the scan lines almost disappear. Whenever I run the test patterns while in one of the switcher presets the images of all the test patterns are doubled. Can anyone help?
