Hey there, I thought I'd ask here before buying a new receiver, maybe I can salvage my current one.
A year or so ago I bought a Denon AVR-S930H
since I had just got a 4K TV (LG OLED C6.) I'm using my previous speakers which are Energy Take 5.1 Classic
(link to cutsheet PDF). I think they should be fine together given the wattage and ohm.
I noticed after a little while I was losing voices altogether. Surround from one side or both side also happened. It can be any channel really. It just stopped or the sound coming out from the affected speaker was really faint.
If I "jiggle" the cables (banana plugged) behind my receiver, I can usually get back all channels for a little while. Sometimes it'll be fine for weeks and then all of sudden it'll start acting up again, plaguing my experience for months.
I noticed the banana plugs aren't solidly held into place. I have room to jiggle them around. Not sure if that's normal.
Here's what I tried:
- Reset the AVR
- Reset the TV
- Calibrate speakers via the receiver (many, many times)
- Bought and installed banana plugs
- Changed wires completely (new roll)
- Disable/Enable HDMI ARC
- Tried 3 different HDMI cables (some older, some modern)
- Re-screwed the wires on the speakers and the AVR (many times)
- Cleaning all the dust I could possibly from plug holes
There's a sale going on and I'm thinking I might buy a new receiver hoping this will fix all my woes. I previously owned a Denon (refurbished too) that didn't support 4K and that one worked perfectly fine, I've now passed it on to a friend and it's still great. However, I think I might try a Onkyo or something like that for a change.
Anything I should try as a last resort? Warranty is definitely expired on this refurbished unit. I'm not very savvy in terms of electronics, I'm not sure looking into it would amount to anything unless there were obvious signs.
