It might be that the battery is drained. If the battery is completely discharged, the phone needs to charge for a while before the battery status light lights up. Charge the battery for at least 30 minutes, and then turn on the phone. .....

i charged it for hours yesterday..and today full..bt its showing the red led...when i remove the charger and tried to turn on it blinks 3 times....i tried many chargers bt its not charging..

the worst problem is that..the phone is from another country..so no warranty..sony service centre guys said they cant do anything because its from another country..they didint even looked the phone to sort out the issue...

while on charge and the red light comes on , try t push the off button at the back of the phone . you find this button by taking out the back cover depress the yellow button with a pen or pencil preferably hair clip or paper clip hold for 8 secs and make sure the device vibrates 3 times connect to pc once this happens and hold volume down as you connect to pc lunch the sus be4 connection to pc

oh..i already done that...still no response....it wont even vibrate now....i cant sort out wat is the real problem...if its hardware problem..i cant service it from my country..service centre says thy wont repair my phone even if it is software issue...**bleep**...

i think i have to buy another phone

yellow button was working before..bt stucked at sony logo...now it is not charging,no response not turning on,bt red led lights when charger connected..and sometimes light turn off and shows sony logo..then turned off and charge....

if it related hardware issue otherthan battery or software i think i better buy a new phone....(hardwares cost almost as a phone)
