WHY WONT MY CELL PHONE TURN ON


Sounds like you need to recharge or replace the battery. If the voltage is too low for the internal processor it will just turn right off again to save any remaining power.

Shutting off and on


That actually is a flaw in the Sansung phone itself, its something in the manufacturing. When getting large messages or multimedia messages the Samsung will power itself on and off. Had the same problem with Samsung.

Samsung washing machine won't complete cycle


If it is shutting off when its in the spin cycle than you either have a unbalanced load or a problem in the shocks that will trigger a false shut off in the spin cycle.Let me know what cycle it's shutting off in.Also if you can catch it right when it shuts off , then immediately try to turn it back on ,if it comes on without hesitation then you can rule out a failing motor .

Set shuts itself off


sounds like a solder issue on the main deflection board. Check for signs of cracked or dull solder on that board. Its the large board on the right looking in from the back
