I have same problem, I bought this phone 6 month ago.

Hi, the motherboard could have been affected. Since you have ever replaced the power supply, its better you get a new motherboard.

Many applications dragging you smart phone power like cleaner app and social network app so please uninstall this type of application

go to your nearest samsung service center they were help you because your phone has in warranty period

the start menu should still work to get to your settings if not and you bought the phone new 7 months ago take it back to the store phones have a waranty for 1 year and they have to fix it.
If you can't/don't want to take it back to the store you can hard reset it yourself (this will delete everything!)
Power off mode, press VOLUME UP and POWER BUTTON at the same time. The follow on-screen instructions to set everything back up again.

the bottom hose came off,or broke thats where ur problem started, the engine over heated and only cracked head didnt seize the engine if u had stopped when the anti freeze or the temp light showed wouldnt have damaged engine, u wrote ran perfectly for month so enginge was good and in law installed correctly,problem was lower hose and not stopping vehicle before extensive damage was done

Ive just had the same thing happen to my highlander dvd/hdd 160g.
Mine lasted just over a year and I have lost the sound as well. It worked perfectly and No problems until sound suddenly disappeared

there are bad solder connections on the pictury tube drive module. have it fixed at a repair shop.. the tech will be mystified that you know what the problem was..lol..

mine did the same thing. take it to the store where you got it and they will give you a new one. apparently its happened before with the motorola rivals, something comes loose inside the phone. when you bring it to the store they should give you a new phone for free. but im pretty pissed off, because when i got my new one they transfer only the contacts. im pretty mad that all my pictures, videos,and ring tones/sounds are gone just because of motorola making me a crappy phone

Your cooling fan sounds to have went out,causing it to overheat and shut down.It also could be something in the fan stopping it from turning.Try cleaning it or blowing it out with it off.But it mostly sounds to have went out.

IF your printer is 2 months old then if not working you can contact Lexmark and get your printer replaced as its under warranty for free by the company ...


Good luck..
