If the suggested solutions fail to resolve the problem or if you encounter an issue not described here, please contact Runco Technical Support. 5. Maintenance and Troubleshooting Table 5-1. Troubleshooting Chart Symptom Possible Cause(s)Solution The system does not turn on. The V-50HD/V-63HD is not plugged in and switched on, or the AC outlet is not active. The DHD Controller is not plugged in and switched on, or the AC outlet is not active. batteries have run out. The HDMI connection from the DHD Controller to the V-50HD/V-63HD is incorrect. Ensure that the V-50HD/V-63HD is plugged in and switched on, and that the AC outlet is active. Ensure that the DHD Controller is plugged in and switched on, and that the AC outlet is active. Replace the batteries. Ensure that the DHD Controller is properly connected to the V-50HD/V-63HD (see Figure 3-2). The display and DHD Controller are both on, but there is no picture and on-screen menus do not appear. Faulty or incorrect video connection between the DHD Controller and the V-50HD/V-63HD. Ensure that the HDMI output from the DHD Controller is properly connected to the PRIMARY INPUT on the V-50HD/V-63HD (see Figure 3-2). The display is on and menus appear, but there is no picture. Incorrect source selection. Source component is not turned on. Source component is connected incorrectly or not at all. Select the correct source. Turn on the source component. Check connections from source component to DHD Controller. A projected image from a DVD is split or otherwise scrambled. DVD player is connected to the Component input and set to progressive scan mode. Turn off progressive scan on the DVD player. Or, connect the DVD player to the HD1 or HD2 input. Image geometry is incorrect. Incorrect aspect ratio selection. Select a different aspect ratio.
Maintenance and Troubleshooting 58 Vistage™ Series Flat-Panel Display Installation/Operation Manual PREL IMINARY The display is jittery or unstable. Poor-quality or improperly connected source. The horizontal or vertical scan frequency of the input signal may be out of range for the display. Ensure that the source is properly connected and of adequate quality for detection. Correct at the source. 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 DHD Controller. Ensure that the source outputs are connected to the correct DHD Controller input.

External Control Vistage™ Series Flat-Panel Display Installation/Operation Manual 59 PREL IMINARY In addition to using the DHD Controller remote control unit, there are three methods of controlling the V-50HD/V-63HD and DHD Controller externally: Using a serial (RS-232) link to send ASCII commands and receive responses to those commands. Using discrete infrared (IR) codes to program a third-party remote control unit. Using an HDMI connection to send Consumer Electronics Control (CEC) commands from a BD player or other source component that supports CEC. The following sections describe these methods. 6.1 Serial CommunicationsThe DHD Controller uses a simple text-based control protocol to take requests from control devices and to provide responses to such devices. This section describes how to send control messages over a serial link between the DHD Controller and an automation/control system or a PC running terminal emulation software. RS-232 Connection and Port Configuration Connect your control system or PC to the RS-232 input of the DHD Controller as shown in Figure 3-9. 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 DHD Controller RS-232 port. Serial Command Syntax Serial commands to the DHD Controller 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 50,16:9 switches to the Composite video input, sets the brightness to 50 and sets the aspect ratio to 16:9. Command strings can be up to 255 characters long. 6. External Control Avoid combining the ON or POWER 1 commands with other commands on a single line. After sending ON or POWER 1, allow at least five (5) seconds for the DHD Controller to power up. If you have enabled the ISF splash screen (refer to Splash Configure on page 46), allow 15 seconds for the DHD Controller to power up. Once it does, it will accept and properly execute multiple serial commands. Note
External Control 60 Vistage™ Series Flat-Panel Display Installation/Operation Manual PREL IMINARY 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 DHD Controller 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 DHD Controller ignores it and returns a minus sign (- >). Table 6-1.

External Control 64 Vistage™ Series Flat-Panel Display Installation/Operation Manual PREL IMINARY 6.2 Using Discrete IR CodesThe DHD Controller accepts commands in the form of IR signals that conform to the Phillips RC5 protocol. Each DHD Controller remote control button has an RC5 control code associated with it. You can use these codes to program a third-party, “universal” remote control unit to work with the DHD Controller. These third-party products usually come with a computer software application for this purpose. For more information, consult the documentation provided with the remote control unit. IR Command ProtocolThe IR control codes have the following characteristics: Each code consists of 14 bits: Two (2) start bits (always 1); toggle bit. This bit is inverted every time a key is released and pressed again. This allows the DHD Controller to distinguish between a button that remains down and one that is pressed repeatedly. Five (5) address bits. The default address is 17 (binary 10001). To change it, select Remote Code from the Miscellaneous menu (in the Service menu) and follow the steps given on page 53. Six (6) data bits. The carrier frequency is 36 kHz, with the modulated pulses having a 25% duty cycle. Commands are sent at a maximum rate of 9 Hz. The following serial commands are meant to emulate buttons on the remote control. Each button has its own serial command, so effectively it is as if you were using the IR remote only you’ll be doing so via serial commands. These commands provide active OSD responses just like the IR remote.
