Delium Android Tablet Fixed
A friend showed me a cheap bought Android Tablet that was defect and asked me to see if it could be fixed. It was completely dead and the battery probably was completely discharged. Although I was not sure I could help him I took it home with me to have a closer look.
Opening these Tablets can be a bit tricky but to my surprise there were only 4 screws on the outside of the case. I removed those screws and continued by first opening the larger aluminium back cover with my Sanhooii tools. That was the hardest part because it was firmly clipped into the Lcd top panel. I then was able to also remove the smaller black plastic cover that was still attached with two other screws that was only visible after removing the larger grey aluminium cover.
The black cover housed the back side camera and the in- and output jacks. (in above photo on the left). And it looked like someone already had tried to open the device without being able to repair it. The battery indeed was completely drained (0V) and I noticed that the 5V DC input jack was blocked inside by what looked like the remains of a broken of plug. And the connector now was only loosely connected to the solder of its copper tracks. So even if I could plug in another fitting 5V adapter it still would make no difference because there was no DC input to the board.
I couldn’t connect my 5V adapter into the blocked input jack so I removed it for further inspection. Next photos show the still damaged input chassis jack before and after removal. The 5V jack had 4 solder connections. Two for +5V and ground and the other two to help holding it mechanically in place on the board when it’s plugged in.
Previous photo showed the remains of the removed parts that blocked the 5V input entry. Next photo shows the outside case that only has 4 screws. And following photos show my Sanhooii tools. And the tool that perfectly helped me to remove the Aluminium grey cover.
Previous photo shows the model of this Tablet on the Aluminium grey cover. Followed by a photo of the position on the board of the defect 5V DC input jack. After the input jack was soldered firmly
back onto the board the screen immediately showed the battery was charging fine again. Next photos show the result.
The battery charging animation presented itself followed by the Android boot symbol, the Android animation and the Delium opening screen.
And the Battery charging screens show that all is well!
Tablet’s 5V DC input jack now fully repaired!
I helped a friend which only took me some time. And I probably repeat myself by saying, it again didn’t cost me much to also fix his device. Only some solder and electricity. Of course not counting the money already spend on equipment, education and practical training. Success is all that counts and our everlasting goal!
