Section 5: Troubleshooting

5.6.12DISPLAY IS “NOISY”

1. Display adjustment at your input source may be required. Adjust pixel tracking, phase and filter.

Noise is particularly common on YPbPr signals from a DVD player.

2. The video input may not be terminated. Make sure the video input is terminated (75 S). If it is the

last connection in a loop-through chain, the video input should be terminated at the last source

input only.

3. The input signal and/or signal cables carrying the input signal may be of poor quality.

4. If the distance between the input source device and the projector is greater than 25 feet, signal

amplification/conditioning may be required.

5. If the source is a VCR or off-air broadcast, detail may be set too high.

5.6.13RANDOM STREAKS AT BOTTOM OF IMAGE

1. If a 24Hz or 25Hz HDSDI signal or a 50 Hz SDI digital PAL signal is used, make sure to use non-

cinema processing. Delete the checkmark from the Cinema checkbox in the TPC's Advanced

menu (password protected).

2. Or, if you do not have access to the TPC's Advanced menu and cannot adjust the processing path,

use your 3rd-party input source to crop off the streaks.
