I have the 2.5 and the 2.7 mhz. They both were fried during power surges (IMO). I have taken them to get diagnostics but I dont think they know what they are talking about. They told me 1 was working and the other wasnt (they swapped parts) I just opened them up and swapped the power supply (from the one they said wasnt working)...what a joy! Still no go. I get the click that says its getting power but it wont turn on. Then sometimes it will turn on for my brother but I can never get it to. Aside from being schitzo and thinking it is just me, could it be the power button? Any ideas?
