When cleaning any monitor do not spray water or cleaner on the monitor; spray it on a clean cloth then wipe the monitor clean. Spraying directly on the monitor will cause damage which is not covered by the warranty, which the store store will have to cover the cost of replacement.
If only half the touch screen is not working, do the following:
- Do a monitor reset, press the menu button
- Locate miscellaneous under the file section
- Locate reset
- Select factory reset and reset the monitor
- Next power down the monitor
- Next power down the client
- Wait at least 2 minutes
- Power on the monitor
- Power on the client
- Factory reset the monitor again
- Calibrate the monitor
