T68i problems

Hi to all I have just bought a T68i that had beer spilt on it. When I got the phone it was working apart from the fact that once you turned it on the key pad would cease to function, no keys or joystick would work not even to turn the phone off. I followed chunkheads guide for water damaged phones (thanks for the great tutorials) and now the phone continiously powers on and off and on and off...... Could this be caused buy a softwear issue or is it more likely to be damaged hardwear. Any help would be much apreciated.

:-? :-? :-?

I have just found that the power amp is stuffed and I need a new one dose anyone know where I can get one in Australia and what the cost would be? or dose anyone have a broken t68 board with good PA for sale?
