I have a very old portable tv and it only has, ant and av/in inputs am i able to hook cable up to it ? my cable box has both hdmi and coax. the tv model is HAIER KXT7020BK.. please do not laugh at me..
If your cable box has coax output (similar to the ANT on the TV), then a simple coax antennae cable will work. Tune your TV to channel 3 or 4 (check cable box manual).
