Hi just joined -- don't know how to create new post yet, any help would be appreciated.

Problem: Sony K800i will not power up correctly, bright white light come on for 4-5 secs then goes out then, continuues to flash at this 4-5 sec cycle.

I power down, remove the battery, remove and clean SIM card, reassemble and hold on/off sw for a longish time

Same result for three different batterys.

Can anyone point me in the right direction to fix this problem,

Thanx in advance
