Make sure you have your TV programed for the input coming from the cable box. Go into menu--input and select your input type,(rca,hdmi etc)

possibly bad batteries in the transmitter. could also be a blocked IR receiver at the TV(do you have something in front of the IR receiver in the TV?) last resort could be either IR receiver PCB or the MAIN PCB.

Hi Gertha
Switch Mode Power Supply.

Either a PCB or a Metal Box. Usually the first place the AC wires go to internally. They fail usually because of Bad Electrolytic Capacitors. Look at the Electrolytic "Tin Can" Caps and see if they Bulge from the top or are leaking on top or bottom,
Replacing these with similar or better values does the trick.
Otherwise replace the whole Power Supply PCB Unit.

Good Luck
