just recieved my toshsiba 52hm84 and after hooking it up have mixed reviews, wanted to know if i am doing anything wrong. on delivery i hooked up the set to an existing hd cable box via a rg6 cable. picture quality in sd is fair at best, the hd channels are only slightly better which was a big disappointment. i then hooked it up to a dvd player which was great and what i had hoped for with the hd channels. the most annoying part is that each channel seems to have different colors, no 2 channels alike and i have to keep adjusting the settings to get a half way decent picture, the colors,contrast and brightness never seem quite right. is anyone else with this set having the same problems? in a few days my cable company will be installing a new hd cable box just for this set, what is the best hook-up from box to set? and will this improve pic quality? the funny part was they had installed a standard box by mistake which broke immediately after they left. when i called customer service they had me go through some re-boot steps to no avail and suggested that i just hook up there cable to my set for a temporary fix until they can replace the faulty box. this would give me just the sd channels but at least it was something.upon doing this i noticed a marked improvement in picture sharpness but the color- contrast quality remained the same. if anyone can help i would really appreciate it as i am uncertain about keeping this set. i bought the tosh after reading a bunch of rave reviews mostly at this forum so i am confused as to why i am having these problems.
