try to charge the device using the wallmounta adapter,. for 2-3 hours. then connect with pc and perform software repair using Xperia Companion

Actually nolramlb is right, red light means battery drained. You have to give it about 30 to 60 minutes to have the minimum charge to boot up but don't try to repair the device unless you are sure that the phone need it and if you plan to repair it at least wait that the battery is at 100%

just few days back my unit shows red light , vibrate once and shut off itself. i send for warranty check and Sony says it was some loose cable on the screen. they get it fixed within a day. i send in on friday and got it back on saturday noon.

Not too sure if yours are the same problem as mine , but if it's still under warranty , send it in asap.

I believe your motherboard has died or the bootsector has been corrupted. Did you try and flash it?
