Hi and good morning,

Are you saying it doesn't play in Dolby now or it isn't recording?

Also how old is your machine?

Thank you

No it's not decoding Dolby digital. It doesn't switch the signal either watching TV or movies. I'm afraid it's sort of stuck on Dolby pro logic 2.
Customer: replied 2 years ago.
It's a Denon av1911. I've had it for 2 or three years.
Expert:  Michael replied 2 years ago.

Thank you for that.

Have you tried a system reset?

Customer: replied 2 years ago.
I did the three button reset.
Expert:  Michael replied 2 years ago.


That should have set the system back to factory which is good.

But this problem if still present is in the Dolby sens circuit portion of the system.

This will requre some good electronics experience as well as the ability to read and understand electronic schematics to fix this. I have found the problem most times on this system to be a transistor NPN type switching that is no longer sending the correct command in response to the signal.This will require an experienced tech.

If you have this experience and the tools I can go further with you;-)

If not your best way to have this fixed is Sears home service or even a local sears as many of them will perform this repair, also Best Buy does these as well but they all send it out. Those two are reasonable and very good art this repair.

Also you can check around if you have a local home audio shop many of them will make repairs now a days.

Let me know what you would like to do, I'm here if you need me.

Please rate my service kindly before you go, it doesn't cost you anything and then you can contact me anytime until we are done.

Thank you!

How much does this repair average cost wise?
Customer: replied 2 years ago.
I didn't pay a whole lot for it so if it's cheaper to just replace the unit verses repair that would be good to know.
Expert:  Michael replied 2 years ago.

Hi well even though it didn't cost you much it is worth the repair in my opinion and I am usually one to say replace it. But the cost for repair will be about $100.00.

If that is ok, you should fix it because this is a nice unit.

But if you really don't want o be bothered with that and can afford, they newer systems are generally a bit less and have more features.

Its really up to you and this problem isn't very serious and easily traced and repaired;-)

Hope that helps somehow lol.
