I have now got 2 x T28's with a similar problem. It is in the power regulation circuit. The phone shows a low battery (due to current drain) and an IC (the circuit diagram I have shows it as N400) gets very hot. I have been told that this problem is not uncommon. Has anyone fixed this type of fault? Is there an upto date circuit diagram that I can download (the one I have does not match the 2 boards I have). Please help if you can, It has now got to be a challenge, I don't want to admit defeat....... Bob.
