I buy this for a second tv in a bedroom . I have a higher-end built-in surround sound system include a Yamaha receiver in my living room . that live room receiver have `` pass-through standby '' or standby pass-through , which be to say that , when the receiver be not on , the tv speaker still produce sound , e.g. , if you want to listen quietly at night . this unit , however , do not have that feature and to compound that issue , it also automatically shut itself off after 24 hour of no user input -lrb- e.g. , volume change or be turn on -rrb- . so when it shut off , there be no tv sound and the way I have it set up , no picture either . and I never want to turn this off - I want it always on standby -lrb- it do not get hot , so no reason I know of not to do this -rrb- , but that do not work . so now I have to manually turn this on and off when use the tv . it work , and the sound be fine , but not the setup I have envision . unless I miss it , I do not see any info . about this on the Amazon info or Yamaha supply info on the product info . page . at first , I think this be someone else turn it off in my house , or a defect , but eventually , I be tell by second-level support that it be work as design . -lrb- this info . be not mention in the product user manual , either . -rrb- so just be aware of this , if you be plan to use the unit like I be .
