Barco G62-W9 — 9,000 lm projector

Check the selected port in Source > Input signal, then look at Status > Projector information > Signal. A display appearing on the laptop does not prove that the projector is receiving the selected format. Record the resolution, format, vertical frequency and color space shown there. If no signal information appears, record that too.

Source > HDMI has separate EDID settings for HDMI1 and HDMI2. Barco specifies 1.4 for HDMI1.4 devices and 2.0 for HDMI2.0 devices. Check the adapter and everything between source and projector as well; changing EDID without tracing the path can cause a different source to select another format.

1. Save the starting input and settings. Trace laptop → adapter → distribution or extension → HDMI1/HDMI2. Record the adapter model, operating-system version and actual output format, and check that the laptop is sending content to that display.
2. Outside the live program, connect a known working source directly to the selected input with a short compatible cable. Table A.4 lists progressive 1920×1080 at both 60 and 59.94 Hz for HDMI1/2. Choose a starting format and change only one variable per test. Note whether Status detects a signal and whether the picture appears.
3. If the direct connection works, restore the adapter, cabling and distribution one section at a time. The section that reintroduces the fault narrows the search; it does not yet prove which component has failed. If the direct connection also fails, compare another source and the other port, keeping the results of each test.
4. If Status shows a signal but the image is black, check Shutter (AV Mute) and the content being sent. To separate the source path from the projector, try an internal Test pattern such as White grid. A visible pattern leaves the HDMI path to investigate. Finish by setting Test pattern to Off and checking the event content.

Start with the lens part number, image size and lens-to-screen distance. Zoom changes image size, Lens Shift moves the projected area, and Focus adjusts sharpness. An unsuitable lens or insufficient distance must be addressed before saving a framing adjustment.

Barco identifies R9802300 as the G lens 0.65–0.75:1 for WUXGA. As an initial calculation, multiplying a 4 m projected-image width by that ratio gives 2.60–3.00 m. Use this to prepare a layout, then check the actual range, measurement reference and full projected image, including margins, before deciding the installation position.

The installation table lists R98017851 as UST 0.36:1, with no zoom range. It has its own installation procedure. Check the lens fitted to the actual projector before applying either specification.

1. Record the lens label, screen width and height, projected-image size, measured distance and areas where people will pass. Have the installation lead check the position and alignment to the screen; any relocation must remain within the approved installation plan.
2. Before showing test patterns, check the beam area and the Hazard Distance precautions for the lens and venue with the person responsible for the installation. Do not infer a safe distance from the projector name alone.
3. With a conventional lens and a clear mechanical travel path, use White grid and check Installation > Lens > Zoom, Lens Shift and Focus separately. If the motors do not respond, check Lens Lock, which disables lens functions. Establish why it is enabled before changing it.
4. For a UST lens fixed in its Lens Support, Barco warns against lens movements. Do not use the previous sequence or Lens Calibration in that condition. Follow the installation and adjustment procedure for that exact lens.
5. Check Installation > Scaling and the source aspect ratio if there are margins or stretched content. Compare the center and corners before and after adjustment. If the internal pattern is correct but the content is not, investigate the source format, scaling or correction. If the pattern is also wrong, retain the lens, position and settings details and continue at the projector.
6. Save a useful position after checking the result. Lens Memory stores up to five Lens Shift positions; do not assume it has also saved zoom and focus. Remove the pattern and check again with the actual slides or show content.
