Hi,

Try to double check the power cable is well connected if so you have to know that some screens come from the factory with some problem and in this case you have the right to replace it from the seller.

Hi, unfortunately the only ways to get the signal to the tv is with either coaxial, the red white and yellow rca cords, or hdmi and also the " RGB " inputs, also called "component video input ". some dvd players have component video outs-that could free up an hdmi port for you-same goes with cable boxes-if you have hd programming then your cable box may have an hdmi connection-if no hdmi it may have a " DVI " port, this is short for digital video interface-you then connect that to flat screen directly or if tv has no dvi input-they have dvi cables for component video inputting ( there will be the retangular dvi jack on one end and red green and blue rca cable ends on the other.). So shy of opening up televion and resoldering the broken coaxial and composite video input ( the yellow cable connection) that's about it. Thanks, I hope was of some use-and good luck, Prodzilla
