Power seems very intermittent. Sometimes when powering on the device, the bottom buttons light up and there is even a burst of music. Other times nothing. Occasionally areas of the display seem to flash a lighter colour, but there is no consistent image output.

I've taken the back off. There is some scratching to the black flat cable from the charging port to the centre of the board. Otherwise nothing obviously damaged or loose.

Any suggestions on how to further diagnose or fix the fault please? Thanks.

However, whilst I was doing the repair, I also disconnected the LCD ribbon cable in an effort to make sure that it was seated correctly in both ribbon connectors as I had seen that sometimes the bottom connector (under the tape) snaps up after tablet has been knocked (which mine has)which causes other issues.

I found it quite difficult to get the LCD ribbon back into the holders and had to flex and bend it quite a bit in the process. Now when I switch on the device it knows what it is (as Samsung Galaxy Note Pro 12.2 appears on the screen) then it goes to the Samsung logo but won’t boot up past this point. I can also display the odin(?) screen when I press the on and sound buttons together. I can also cancel the odin screen with the sound button.

Any ideas what I should do next? Or should I just end my foolish endeavours and take it to someone who knows what they are doing with these devices. Am hoping I haven’t totalled it with my fiddling!

Any helpful suggestions gratefully received.

Many thanks’

My wifi seems a bit slow and I wanted to check the antenna connection. I've opened the back of the tablet and looked under all parts but can't seem to find the antenna. Can any tell me where it is?

Here's a picture of the tablets, can anyone point out where the antenna is?
