My k850i wont power up.

what is the model of your tv?

Try different battery if it dosent works its defective and needs to be replaced, go to service provider or manufacturer

Perhaps the connection got clog up and mixed up. Try opening your front phone cover and wipe it.

take it to a phone repair shop is best advise i can give as it seems there is more wrong than just the lcd

something is wrong with the sceen, bring it to your provider and they would be sure to help

2 things, first bad battery, sometimes bad battery works for few minutes then your phone just dies on you, it says its fully charged but it aint. That red light flashing only means that your phone has LOW BATTERY. 2nd your phone software has problem. If you have another ericsson that uses the same battery you can check it the battery is ok, its the only way you can find out if the battery is good. If the battery is doing ok with another cellphone then your cellphone software has problem.

i fixed this on mine by using sony ericsson update service

you reprogram your phone

CPU faulty send it back to Sony Ericsson for repairs, this is a common problem on Siny Ericsson very bad.
