The subject receiver 0252-3005-9404 has software 0x147d installed 1/26. It has a wired ethernet connection and connects through a Demon AVR 700. Generally in the mornings the tv (Sony XBR900F) may come on for a few minutes,then the screen goes black with the message "No Signal - change your input". The DTV receiver stays on while the tv is off. Restarting the receiver, sometimes twice, corrects the problem. Then normally all is perfect until about 5:30 pm when the exact situation happens and the receiver has to be reset. CSR has not been any help as communicating with a tech whose first language is most definitely not English is difficult. Thanks for your consideration.
