Are You Experiencing These Common Display Problems?

Today’s markets demand a variety of display and Point of Sale solutions that range from industrial to commercial terminals, and there are glitches with any product. Use this list to identify a problem description and get your hardware off the sidelines.

•Video defects are one of the most common and readily identifiable problems with display and POS terminals. Typically indicated by a white fuzzy screen, often with rolling lines, video problems can be deeper than simply a bad LCD.

Certain degrees of discoloration on the LCD panel will signify a backlight issue, and result in either the panel or backlights being replaced. Wavy video or no video at all are classic symptoms of video board failure that require replacement or component repair.

•Not powering up, or a black screen indicates an “Out of the Box Failure.” Troubleshoot the problem before returning the terminal, check the cords for cracks and connectivity. Many times a unit is returned faulty without establishing a proper power source.

If all connections are ok, and the terminal doesn’t power on, the Power Supply Board could be damaged and needs to be replaced. Other reasons for no power include a short fuse or bad capacitor on the Video or Mother Boards. Foreign objects found in the terminal, such as paperclips, can also create havoc for your hardware and cause multiple failures.

•No touch response can reduce the most interactive terminal into an ineffective paperweight. Non-responsive touch terminals need new glass, which is a substantial repair. Check the USB/Touch Interface Cord first to make sure that the cord and port are not damaged or loose. A loose port may need to be re-soldered, or the Touch Controller Board needs repair.

•The terminal is not connecting to the internet or system applications. For units that are hardwired to the internet, but still have connectivity issues, check the network jack connector pins for alignment and damage. Be sure to replace a damaged cord or identify the damaged port.

A short in the Main Board Network Chip may also be the problem. The Main Board Network Chip or “IC Chip,” can single-handedly ruin your terminals connectivity and component repair is needed to address this issue.

•Lagging terminals and software problems deliver a weak user experience and often signify neglect or misuse of a terminal. When a system is slow, freezes or is unresponsive, it’s mainly a Hard Drive issue, and the HDD will need to be replaced. Sometimes a Mother Board can be the cause of slow operation and require rework repair.

There could be a very problematic virus pillaging your company’s software and require immediate attention. It is best to note any persistent problems with software operations and sustain an adequate maintenance plan for your terminals.
