Operating the display with access panels or the front screen removed can expose service or operating personnel to ultraviolet burns and high electrical voltages. Always wear ultraviolet- blocking eyewear with side guards when servicing the display.

For Standard Screens, removing the screen provides service access to other replaceable modules from the front of the display. Service access for units with Ultra-Thin Mullion Screens is from the rear only.

Lamp Replacement, Front, Standard Mullion Screens

CAUTION For the standard screens, with the wider mullion, the screen may be removed by hand from stand-alone displays without damaging the screen. Where screen edges are adjacent to each other in a video wall, removing the screen without a screen removal tool may damage the female part of the screen latch. In video wall configurations, use the SRT-100 Screen Removal Tool (see instructions below and Options on page 2) to prevent damage to the screen.

Follow these steps to remove the standard, wider mullion screen and replace the lamp, if the display unit is not built into a video wall. Read all the steps before starting.
