Incoming Inspection

Unpacking the Touchscreen

Handle the touchscreen with care. Note the transducers in the corners are especially fragile. Note the location of the transducers and wiring. If any of these are accidentally broken during handling or installation, or if a wire is pulled loose, the touchscreen will not operate. Avoid excessive handling and stress on the touchscreen cable. Wear gloves to avoid getting fingerprints on the touchscreen. The touchscreens are pre-cleaned by Elo.

Testing the Monitor

The CRT display must be in good working order before beginning the installation of the touchscreen. Inspect the monitor for cosmetic flaws or damage. With a new display, it is suggested that you test the display by running it overnight. Check for acceptable color, linearity, brightness, contrast, distortion, and other QC tests.

Disassembling the Monitor

Disassemble the monitor on a large, well-lit work surface. Leave space to set aside major display components. Group screws and other hardware in small containers or in specific areas on the work surface as you remove them, in relation to the part of the display where you are working.

Most display manufacturers connect the major components with detachable cables that have labeled and keyed connectors; these cables are of lengths that will usually connect to only one place. Also, screws are identifiable by type and size, and usually will not fit in the wrong place. The most difficult problem with missing or wrong hardware or connections will be with ground cables that attach to obscure ground points on the metal chassis. When in doubt, make notes of the connection points.
