Please show me how to turn it back

if it is showing the power cycle...you need to reflash the OS

needs new motor and poss pcb assy ...needs testing.

My 3110c phone won't turn on anymore. Help!! I just turned it off one time and when I try to turn it back on, It won't turn on completely anymore. It will still show the nokia screen and then a white screen will flash 3 times and then the phone will turn off. Could anyone help me please?..

The flood switch at the base of the dishwasher (under the drawer) has triggered.

You will need to turn the power off (at mains) and extend the drawer as much out as possible. Use towels to dry the base and if possible use a hair dryer.

Turn power back on and try.
Possible causes are kink in drain hose (or crack), foaming detergent (use recommended powder).

Please rate this solution if satisfied otherwise post a comment.

All you have to do is this: While it's off(red light is on) hold down the ON button until it turns on then turns back off. Now just turn it back on normally and it should greet you with display settings. Hope this works!

When the TV is on, need to check the back light is on(go back side & look into through)

If the back light is on -- need to exchange the Main Board
no back light -- exchange the Power Board --- 95%
exchange the LCD panel --- 5%(inverter)
