Hi, Eatoy boy, in need of help, you know that my LED TV turned off and does not turn on after connecting a USB cable with a shoe or tennis led. After that it didn't turn on anymore my question is if they could help me see how I recognize and test the part that is short or damaged to repair ... thanks

Excuse me, my innocence returned. To measure I must be able to use alternating or direct current and that scale ... sorry for being so annoying.

Thank you for your help but I still can't solve you know that I have a voltage of 60 vol coming out of the mainboard to the main board my doubt is if I am measuring badly ... I am putting the neutral on one side of the test and with the Another tip of the East I look at the exit of the plate marks me 60v all the outputs

badly, the mass or negative of the tester goes to the secondary of the chopper transformer, negative of the filters or electric capacitors of each voltage.If it had 60 volts towards the main it would have all blackened.
