Hi i dont know if this is a help but i have the same tele & mine had the problem of when watching tele it would shut off & like yours it would have just a green light on but tv was as if in stand by. if i used remote hit stand by & red light would show. now again turned on about 5 - min same again...anyway . it sounds that yours has its constant on green but hey this remidy is worth a go... how i cured my tele problem from cutting off & just having green light is to remove the back & just litraly clean the dust out of it by blowing it off or get a can of compressed air.. since i have done this i havent had the problem as before but what i think it may be is that due to alot of dust in the tv back, it could be just shorting a terminal some where..
to take the back off..remove the stand & the screws around the edge of the back..also one by the areial input & the cover will just pull off. hope this helps you as it did me
