Question about Sony Ericsson K790a Cellular Phone

1 Answer

Cannot turn my k790a on...

My phone was working ok, i didn't drop it or something like that. I just turned it off for night. Then I am not able to turn it on. When I press the "power" button on the top of the phone InfraRed port is blinking with a red light and that's it. I thought I had ran out of battery power. When plugged the charger in, the same problem, InfraRed port was blinking with a red light. It cannot even recharge. I got another battery of the same type, but the same thing is happening. I tried to put another SIM and I also tried without any SIM card, but no help, same thing.
What could be the problem?

    I've had the same problem twice. What I've done and has solved it is:

    1. Take out the battery and connect the k790a to the AC.

    2. The screen will start blinking blank. Let it do that for a minute.

    3. Insert the battery WITHOUT disconnecting the charger from AC.

    4. The Sony Ericsson logo should appear in a few secs.
    Sometimes you have to try two or three times until you get the logo back. Hope this helps, Bye!
