HKC P774A Troubleshooting

Device does not visually or audibly respond to power commands.

The device may simply require a charge. Connect the mini USB (supplied by HKC) to the charging port. If the device does not respond after it is connected to a functional Mini USB then the battery will most likely need to be replaced.

Dirt or grime may be locked into the power button housing. Cleaning the area may solve this problem. If this does not work, the power button may have lost physical connection to the mother board.

The device is functional but does not begin to charge once connected to a charger. A new charger will need to be purchased. The device requires a Mini USB.

If previous problems have been ruled out, the most likely cause of error is a faulty motherboard. With technical skill the motherboard may be repaired, but it is recommended that it be replaced.

The device shows signs of being turned on (sounds heard when booting up), but the screen remains black. This section also includes the device freezing.

The device may not be displaying anything, because it is simply not powered on. This problem may be addressed, by holding down on the power button until the device turns on.

The tablet may be frozen and the screen unresponsive to touch. To solve this, the restart button on the bottom left of the device should be pushed and held until the device restarts.

The LCD is connected to the motherboard via a wire on the inside of the device. The disconnection of this will result in the screen not displaying anything. This problem can only be fixed, by physically reconnecting the LCD display to the motherboard. The wire connecting the two may damaged, which will require replacement.

If all of the previously mentioned problems were addressed, the likely cause to a malfunctioning display is a faulty display. If this happens, the LCD screen need to be replaced.

Device will not establish a wireless internet connection.

It is possible in the settings of the device the WiFi is not turned on, so it would not be receiving a connection to the possible networks available. It is also a possibility that the device’s airplane mode is activated so it would not connect to any sort of internet. To fix this, slide your finger from the top of the display and select either the WiFi icon ore deselect the airplane mode icon.

If the WiFi is still not working and it is turned on and the airplane mode is off, it is possible that there is no exterior WiFi available to connect to and/or the router is turned off. It is also possible that the WiFi is secured and requires a password to be actively used. Another possibility is that the WiFi is simply not actively working, there is a connection error and the device cannot connect due to the WiFi being “down," a probable cause to this is the cables and cords at the router are not properly connected.

The screen may display information, however it is unresponsive to touch commands.

If the screen is unresponsive, but not visibly cracked the digitizer is most likely the cause of the unresponsiveness. The digitizer is the glass screen that is in front of the LCD. This must be replaced, as it can’t be repaired easily.

If the screen is cracked, the touch sensitivity on a device like this would be limited. This condition can't be rpaired, and the entire screen must be replaced.
