Device will not turn on ¶
No matter what you do, you can't get your tablet to turn on.
Drained or bad battery ¶
If your tablet won't turn on, especially if it has not been used in a while, its battery simply may be drained. Plug the charger cord into the bottom of the tablet and allow it to sit for a few minutes. The tablet should recognize that the cord is connected and it is now powering up. If this is not the case, you may have to replace your battery.
Power button malfunction ¶
If your device does not respond to the power button being pressed, but responds to everything else, the power button assembly may have failed or become disconnected from the logic board. You may need to check the assembly has not detached from the logic board or replace the power button assembly.
Display malfunction ¶
If the battery is properly working but nothing appears on the screen, the LCD display may have failed or become disconnected from the logic board. First, check if the ribbon cable running from the display to the logic board is securely in place and not damaged. If it seems undamaged and properly secured, then you may have a faulty display and it will have to be replaced.
Logic board malfunction ¶
If the battery and display are both functioning properly then the logic board may be the culprit since it passes and processes all information to the display and from the touchscreen. In this case the logic board will need to be replaced.
Touch screen not responding ¶
Your tablet is not recognizing touch input on the front panel.
Loose connection to logic board ¶
If the touch screen is not working, you will need to check to make sure the connector running from the touch screen to the logic board is snugly in place, since a bad connection to the logic board will inhibit the ability of the device to detect input.
Damaged touch screen ¶
If the touch screen is fully connected and still not detecting touches then It is possible your touch screen is damaged or has malfunctioned. You may need to replace the iVIEW-754TPC Digitizer Replacement
Damaged logic board ¶
If replacing the touch screen does not restore touch input, then the logic board may have failed on the device since it handles input from the logic board, or the connector which attaches the touch screen to the logic board may have failed. In either case, you will need to replace the logic board on the device.
Audio not playing from speaker ¶
Your tablet turns on and functions normally but there's no audio output from the device speaker.
Broken internal speaker ¶
If you do not hear any sound from your device when no external headphones are plugged in, then you may have a broken internal speaker on your device. Try rebooting and resetting the device first to make sure it is not a software issue. If that does not work, then you will need to replace the internal speaker in your device.
Broken external headphones/speakers ¶
You may have faulty headphones or external speakers. Plug your device into any other pair of headphones or speakers you have and check if any audio plays. If no audio plays from the new headphones or speakers, read on.
Loose audio jack ¶
Your device may have a faulty audio-out jack. First reset your device to make sure that is no software issues causing the problem. If your device still fails to play audio, you will need to replace the speaker audio jack. If replacing the audio jack does not solve the problem, your logic board will need to be replaced.
Device not charging ¶
When you plug in your device it does not display as charging.
Damaged power cord ¶
You may simply have a faulty power cord; try using a different power cord and see if your device begins charging. If your device does not begin charging, read on.
Loose or faulty charging port ¶
If switching the power cord does not begin charging your device, then the power jack on the device may have failed. In this case you will have to either replace the DC-5V port at the bottom of the device where the charger plugs in or use the micro USB port for charging the device.
Device cannot connect to camera ¶
When opening the camera application no image is displayed on the screen.
Software issues ¶
You may have an application that failed to install correctly or another application may be taking control of the camera, restricting the application you are attempting to use from obtaining access. If this is case try re-installing the application, restarting the device and then opening the application back up. If you camera still does not work, read on.
Broken Camera ¶
If a blurry image or no image at all appears on your screen you will most likely have to replace the camera in your device.
