Toshiba 65hm167 red lights

well ever since i got my cable installed,my tv 65hm167 has stopped working, you hear the tv click on but screen is black, then it shuts down on its own,then you hear as it is turning itself back on, then i noticed the fashing red light, so i call these people to come fix the problem,and they say it will be a while ( days ) so i get upset and tell them to come pic up their equipment and cancel my service and for them to repair my tv. so i get the run around and the sales guy comes to my home and checks connections, and he said one of the coax cables are bad / not working,so i asked him is that how they install ?? not checking connections before the tech leaves. so now i have to call the damage claims to get this resolved. tv was working fine before they installed the cable and the sales guy knows this because he programmed my tv before they brought out the box,and plus the install tech had to call someone twice from my wifes phone to ask questions on how to install the calbles. plus the antenna plug in the bback of the tv is bent , how ? i dont know. but is there any reset steps i can take to see if its anything, sometimes the tv turns on light is green,but no picture, cant switch sources,and when i had the cable direct into the tv,i heard sound but no picture,then it started to shut itself off then click back on or maybe it was just a clicking noise.let me know if any of you had this same problem, well as far as the tv issues not cable install issues
