Denon AVR 1612 hissing speakers problem

[vcdentro]

Hi there,

I have a denon and when i turn it on it always sounds hissing on the speakers, then as time passes by it dissapears except on my left surround speaker. Do you know how to fix it or if this is a common problem?

Thanks.
Best,
Tyler

I hv a 1910 and it doesn't have this problem. If it isn't under warranty it is best to check with authorised service centres

expired warranty, any suggestions?

I had the same hissing problem, I think it is a problem with the hdmi board. What I did was to completely remove the boards and clean them using lcd monitor liquid cleaner and let it dry for a few minutes under sunlight. You can try isopropyle alcohol/petrol for cleaning the board. And, never buy a Denon AVR again!

And cleaning worked it out?
Do you have a guide or disassembling is easy?
By the way, i want to buy another amp, what do you recommend?

Cleaning does seem to resolve the issue in my case.

Removing the board is easy, remove the avr top cover, remove the data cables connected to the hdmi board, then remove all the screws of the hdmi board at the back of the avr. After this you can easily remove the board.

Before cleaning or removing the board, try removing the data cables connected to the hdmi board, then connect after a few minutes. This may clear the problem sometimes.

I don't know what avr options are available in your location, but Yamaha seems to be good.

would you prefer yamaha over onkyo?

cleaning all the amp didn't fix it, neither resetting.
I spent 3 hours disassembling, cleaning and drying for nothing!

?? ... you did learn how to disassemble and set it back!

 

[vcdentro]

Yeah, i did it carefully, finding out how to do it, that's why it took me a few hours.

May be your hdmi board is faulty. Better take it to a servicing center.
