If your table is working when plugged in but shuts off when unplugged, you have a dead battery and it needs to be replaced. For the iVIEW-754TPC the battery is replaceable, but it will take some work. To reach your battery, you will need the plastic opening tool to take off the back cover. A tip for taking off the back: start from the bottom, and work your way to the top clips; this will make removing the back easy. Then you can see the battery is attached inside, it will not just lift up. You will need a spudger to free the battery from the glue underneath. Slide the spudger under the battery (you might have to put some force into this) to release the battery from the glue. You will have to go around all sides of the battery to free it. The final step for removing the batter involves soldering. You should have noticed that the battery is connected to the logic board with two wires which are soldered on. You will need a soldering kit for this part to de-solder the wires. Now, you will be able to put a new...
This screen is fairly easy to replace. You will not need a heat gun, since the LCD display and digitizer are not fused together. However, you will need to remove all of the components on the inside to get to the digitizer. For this repair you will need the plastic opening tool, a screwdriver, tweezers and a spudger. First you will used the plastic opening tool to take the back case of the tablet off. Then use the spudger to free the battery from the glue that is holding it down (but be careful not to tear off the soldered wires connected to the logic board). To remove the logic board you will need to find the 5 screws and take them out. Then you will use the tweezers to gently remove the tape holding the wifi antenna down, and also to disconnect the digitizer. Now the logic board with the battery can be removed, and you can set that off to the side. For the last step, take the plastic opening tools to remove the LCD display from the clips which are keeping it connected to the digitizer. You will now be...
First, try using the micro USB port to charge the device, then try turning it on again. If your device still does not turn on, it is possible you have a problem with the display. Does anything show on the screen when you try to turn it on? There are two possible solutions: 1. If the display is not working, open the back of your device and check if the ribbon cable running from the display to the logic board is securely in place and not damaged. If it is not damaged, then you may have a faulty display and it will need to be replaced. The digitizer and LCD display are not fused together on this device, so this is a fairly easy fix. 2. If the display is working but the device wont boot up, then the logic board may be the problem since it passes and processes all information to the display and from the touchscreen. The logic board is slightly difficult to replace because it could involve soldering. If you look online you may be able to find someone selling the logic board with all the parts attached to it...
