Why no sound through Denon AVR-1508 with Sony BDP-S5100?

SOURCE: Denon AVR-3802 Problem

Check that your speaker cables are not touching each other at the amp end and also at the speakers as this will cause the amp to shut down.

hope this helps.

If your amp looks like it's going to work as normal (ie the front display lights up as it should etc), but then the amp goes into protection mode when the anti-thud circuit times out, then I know what's likely to be wrong.

It's one of the power amplifier channels which has gone faulty.

I just found this out after having this problem with my AVR-1906.

I took the amp apart and de-soldered the suspected channel power transistors (centre channel in my case).....and hey-presto! it fired up as normal (obviously the centre channel would be out of service).

I have ordered the replacement transistors from Farnell (UK) at a miserly cost of around £2-£3 each.

Just waiting for them to arrive.

An alternative is, if you don't use all your channels, take the transistors from a known working but not needed channel and swap them over with the duff ones.

Hope thats of use!

There is a setting under your speaker setup to turn the subwoofer on. If speakers are set to small it auto matically sets the subwoofer to ON. If the speakers are set to large it turns the subwoofer off but you can manually adjust.

Turn the unit off by main switch (not a standby button).
Press and hold "Speakers-A" and "Speakers-B" buttons and turn on main switch.
