My handset ran out of charge and when i had recharged it and tried to power up my phone, it went to the flashing samsung logo and wont go past it. I tried taking the battery out for an hour, replaced it and powered on again and its still sticking at the samsung logo. Can it be fixed. help me sir.....

im not sure but could it be a comparability issue with the device and the wake up signal from the device to the tv? android systems use a Linux based file system, so the problem may be in the tv's input settings. hdmi input from the device to the tv. and then go to tv input mode and see if putting the device in another hdmi port doesn't work.
