been using my 2308CI since I bought it in 2007. It's been moved three or four times in its life, but its been stable here since at least 3 years. When I mean use I mean power-use the $#$ out of it; I believe there is not that many inputs/outputs not currently plugged in - and most of the inputs are being hacked at in both analog & digital. (You know, trying to keep all your nostalgia consoles + the current ones, and Chromecast, and tvbox, and BD, etc.)
since the last year, I've been witnessing a drop of the right channels from time to time, no matter the input. (Well, can't say that I,ve witnessed it on all inputs, but deffo on the digital ones). Sometimes it drops only under a certain volume - but cranking it up again won't revive it.
Powering down & powering up the unit usually brings it back. This mornin though, Both channels were down. At first I thought my kids had messed with a param (like A/B, analog, Z2, etc.) but no... it really wasn't outputting anything (while pretending to be.)
Again, a power down & power up brought it back but... I fear for its life now. Sad thing is I have no desire for now to upgrade it, I'm fine with stereo (yeah, my surround years are behind me - was way too much into the useless pro logic when it started, worked my way up to 5.1 but now couldn.t care less. Maybe when the kids will be older, and we finish that basement... ) Its basically, for me, a stereo amp but with a kickass HDMI/opt/analog avr switch & upconverter.)
What do you guys think ?
I have no technical reasons to back it up, but my 'feeling' is the pre-amp is going away. Or I guess it could be the power amp.(lol) Being digital, I can't really play with the pre-amplified input volume.
I'm thinking some kind of 'relay switch' doesn.t activate anymore under a certain level of volume...if that makes any kinda of sense.
I obviously will try to mend it on my own, after a few suggestions from your side (electrical engineer here, but haven.t played inside an amp in ages, let alone a digital one.) I mean I can swap a few caps or two, but I won't characterize & overhaul the whole thing like I did on my good ole analog sansui. Anyhow, I assume that everything's mostly handled by a set of ic chips.
I'm only mentioning this for the sake of giving all the info && because I have seen someone mentioning something about PQ.
In the last months, the picture has become grainy as F*. I mean, like if the sharpness controls went to 200% and full backlit, no noise cancellation (a bit like a very robust 'game mode'). I always thought it was my TV that was going out (its 5-6 years old, plasma) - I had resetted it, played with all the controls, but to no avail.
Any solid surface shows signs of grains, as if it was snowing (well it is snowing currently, but outside
Anyways - ANY comments appreciated (even if making fun of me)
