Maintenance and Troubleshooting Runco VX-2ix Owner’s Operating Manual 49 5.3 Troubleshooting Tips Table 5-1 provides some general guidelines for troubleshooting problems you may encounter with the VX-2ix. If you encounter an issue not described here, please contact Runco Technical Support. Table 5-1. Troubleshooting Chart SymptomPossible Cause(s)Solution The projector does not turn on after initial installation. The power LED lights red after you press the power button. The VX-2ix is not plugged in or the AC outlet is not active. Ensure that the VX-2ix is plugged in and that the AC outlet is active. The projector is on, but there is no video image on-screen. Incorrect source selection. Source component is not turned on. Select the correct source. Turn on the source. A projected image from a DVD is split or otherwise scrambled. DVD player is set to progressive scan mode. Turn off progressive scan on the DVD player. Connect the DVD player to the HD/RGB 1 or HD/RGB 2 input. Image is too bright and/or lacks definition in the bright areas of the image. Contrast is set too high. Lower the contrast setting. Image appears “washed out” and/or dark areas appear too bright. Brightness is set too high. Lower the brightness setting. Colors in the image are swapped; for example, reds appear blue or vice versa. The Red/Pr, Green/Y or Blue/Pb outputs from the source are connected to the wrong inputs on the VX-2ix. Ensure that the source outputs are connected to the correct VX-2ix input. Image geometry is incorrect. Incorrect aspect ratio selection. Select the aspect ratio that best matches the source image and screen size (refer to Table 4-1). The projector will not turn back on after it was powered down, or the image disap - pears during operation. The projector will not turn on for two minutes after power-down, to protect the lamp. The lamp has failed. Wait two minutes until the LED at the front of the VX-2ix turns red.

Runco VX-2ix Owner’s Operating Manual 51 6.1 RS-232 Connection and Port Configuration To interface the VX-2ix with a home theater automation/control system or a PC running terminal emulation software, connect it to your control system or PC as shown in Figure 3-10. Configure the RS-232 controller or PC serial port as follows: no parity, 8 data bits, 1 stop bit and no flow control. Set the baud rate to 19200, to match that of the VX-2ix RS-232 port. 6.2 Serial Command Syntax Serial commands to the VX-2ix take the following form: Commands are not case-sensitive. For a single command that takes no parameters, type the command followed by a carriage return; for example, to set the aspect ratio to Letterbox, type LETTERBOX . For a single command that takes a parameter, type the command, a space or a comma and the desired value followed by a carriage return; for example, to set the brightness to -10, type BRIGHTNESS -10 or BRIGHTNESS,-10 . You can also send a string of multiple commands on a single line, separated by commas. For example, COMPOSITE,BRIGHTNESS 100,ANAMORPHIC switches to the Composite video input, sets the brightness to 100 and sets the aspect ratio to Anamorphic. Command strings can be up to 255 characters long. Table 6-1 lists the RS-232 command set. The “Parameter (min/max)” column shows the valid parameter ranges, or “NA” for commands that take no parameters. When you enter a valid command, the VX-2ix executes it and acknowledges it with a plus sign on the command line (+ >). When you enter an invalid command – one that is misspelled or followed by values outside the valid range for that command – the VX-2ix ignores it and returns a minus sign (- >). 6. Serial Communications Avoid combining the ON or POWER 1 commands with other commands on a single line. After sending ON or POWER 1, allow at least 15 seconds for the projector to power up. Once it does, it will accept and properly execute multiple serial commands. Table 6-1.

Specifications 58 Runco VX-2ix Owner’s Operating Manual Brightness and Contrast: Cinema Standards Measurement System (CSMS) Specifications - Brightness: 52.1 foot-Lamberts (fL) - Contrast Ratio: 271:1 These measurements are taken from the projector in a controlled, home theater environment. All measurements are made to ANSI/NAPM IT7.228-1997 specifications using the Photo Research PR-650 SpectraColorimeter and Minolta LS-100 Luminance Meter, Video Essentials test DVD and a 1.3 gain, 72-inch wide screen. The projector is calibrated to a color temperature of 6,500K and has a minimum of 150 hours of usage. The foot-Lambert (fL) is the unit of measurement used in commercial movie theaters to express image brightness at the screen surface. The Society of Motion Picture and Television Engineers (SMPTE) specifies 16 fL as the target image brightness for film-based projectors using an open gate (without film in the projector). More importantly, today SMPTE specifies 12 fL as the target image brightness in Digital Cinema theaters. The foot-Lambert measurement is dependent on screen size, screen gain and projector light output. Home Theater Calibration Specifications - Light Output: 1227 ANSI Lumens - Contrast Ratio: 271:1 These specifications are obtained by calibrating the projector as described above for CSMS measurements. Industry-Standard Specifications - Light Output: 2500 ANSI Lumens - Contrast Ratio: 3100:1 These are typical projector brightness and contrast specifications found in most companies’ sales literature. Runco includes these measurements in its literature to allow for direct comparison with other manufacturers’ projectors. These measurements are typically taken at 9,000K to 13,000K to get expected performance data when the projector is used in professional, commercial and industrial displays.
