Does the unit light up...standby light...anything?? If the unit is completely dead then you have a bad stand-by power circuit...98% of the time the stand-by transformer is bad. It is a tiny transformer usually near the back of the unit and MOST of the time right where the ac line goes through the back panel. To test this part you need an volt-ohm-meter or digital multi-meter. The input side of this transformer (side where ac goes into) must have continuity (current will pass through it). It most likely will read "open" on the meter. This part is available from tritronicsinc.com. Good luck!

My HTR 5460 won't stay on


try pressing power while holding the 'fm/am' and 'input mode' buttons. This will tell you what part of the circuit is making it shut down. It should show something like I PROTECT, PS PROTECT, etc.

Hmdi input has lost audio


several things could cause that:
1. hdmi cable is no good.
2. receiver and TV are not fully compatible. I noticed few times that philips tvs had problems with denon receivers. Some times you need o unplug hdmi cable and plug it in back to get sound.
3. firmware issue. depends on model of your receiver there could be a software upgrade to resolve the problem.
4. somebody (kids) accidentally pressed some buttons and reassigned video input for that video source (video select button on a remote control), etc. Resetting the receiver usually helps.
5 Receiver (hdmi board is no good) or TV is no good.
so next time when it happens check video source, video input assign then try to swap hdmi cable and TV

My remote will not cut on my Bose Cinemate system. I have changed the batteries in my remote and the red light on the receiver is illuminated, so I know the system is operational, . I've also unplugged...


It seems to be a common misconception that the remote is necessary to turn a device on. All devices have hard-wired power controls. Does THAT work? It is unclear which device (remote or the Cinemate) is malfunctioning. If the Cinemate won't turn on by its own power switch the remote won't magically bypass whatever the problem is.

The Cinemate Manual offers some steps to take if it won't turn on, as well as other guidance.
