Troubleshooting Tips
The VideoWall/CineWall provides several features for identifying and resolving product
performance issues. If the solutions suggested here fail to resolve your issue or if you
encounter an issue not described, please contact Runco Technical Support.
On-Screen CodesThe On-Screen code is a sequence of red and amber lights that flash on the screen to
indicate what is wrong. These flashing lights are particularly helpful when the lamp won’t
turn on.
Turning on the On-Screen Codes: To view the On-Screen codes, do one of the
following:
• Select Unit Status from the Diagnostics menu.
• On the remote control, press and hold the ISF NIGHT button while simultaneouly
pressing the MENU button. (Use this method if the lamp won’t turn on.)
You should see the red or amber lights flashing on the screen. You should also see the
Unit Status menu, unless of course the lamp is off.
If the picture is bright, it may be difficult to see these lights. They are soft, out of focus
lights. Move around to see them. Or, send the RS-232 command CURTAIN
to make the
screen black so they will be easier to see. (For more information on RS-232 commands,
refer to
Serial Communications on page 57.)
If you see a steady, unblinking, amber light, it means the lamp is on and there are no alarm
conditions. If the screen is black at this time, it could be for any of the following reasons:
• The curtain is on and black.
• The source itself is a black picture.
• There is no source, which turns the screen black.
• There is some foreign object blocking the light path.
Automatic On-Screen code display: If Auto Codes is checked in the Miscellaneous
Options menu, the code appears whenever there is a fault event that forces the lamp off.
