So i was playing ps4 one day and randomly it stoped projecting on my tv i tried many different cables and nothing. But then i tried it on another tv and it worked. But the tv is not broken because my cable box works through hdmi. Can someone help me

Does you T.V. have more than one HDMI? If so try switching you PS4 and cable spots. If not then check your T.V. settings and PS4 as well.
