My 45TX is losing its MCACC settings. I'm not sure when. I think a power interruptions may be causing it but I think that may not be it.


So anyway the MCACC setting are resetting once in a while back to default and it is annoying. I thought maybe their might be some type of cheap battery in it that is dead after 6 years but if so I can't find it.


I may order a service manual. Does anyone have a copy they can .pdf and I'll pay you some cash?


Anyway, any thoughts?


Its losing its brain and I've lost mine.


Thanks in advance for any input.

I think the 45TX knew I was going to buy an SC05 and decided to go on strike.

Is it completely losing the Auto-MCACC calculations (requiring you to re-run the calibration) or is it just turning the MCACC feature off requiring you to re-engage it? The 45TX is a great receiver, one of the last before the Elite line started tapering off amplifier/power-supply quality in favor of AV features... this is coming from a 43TX, 1014TX, and 82TXs owner. The new SC line is a great step back in the direction of top-notch amplification, and has all of the great AV features to boot.

Hi Stephen!


I think I remember seeing your posts many time. It is requiring me the re-run the auto calibration. However, now that you say it - I never checked the memory to see if it has the settings left to reload.


Any idea on what could cause this? And I totally agree with your assessment and I love the new SC05 and I'm really glad I waited past the 90 series.

I ended up with the 82TXs as a gift... actually received a Yamaha V1700 and exchanged for the Pioneer... and its amps weren't near the 43TX and probably only on-par with the 1014TX (no slouch, but I expected more from the 72/74, 82/84, and 92/94).


I'm unsure on what would cause it, but it sounds like either loss of some sort of battery backup or corruption of the internal memory. Either way it could be a cheap/easy fix, or could be unproportionally expensive. The next step in self-diagnosis may be to figure out when it's losing its memory and if it's related to a loss in power or random. You could test by unplugging for a few minutes or maybe a couple of hours and see if this causes it.


Either way, good luck!

thanks Stephen! I paid $1000 bucks for that 45TX in 02 and it has brought me many times that in pleasure.


I hope the new SC05 does that well the next 6 - 10 years.

I paid $550 for my 43TX in the summer of '03... it was a steal at the time. From there I "upgraded" to the 1014TX for Auto-MCCAC which was a lateral move, but I broke even selling the 43TX so it didn't bother me much. Like I said, the 82TXs was basically a gift, but its amplification was on-par with the 1014TX but a step down from the 43TX. The 82TXs was later hit by lightning and insurance money replaced it with an Onkyo SR805 that I'm pretty much thrilled with other than its poor component-to-HDMI up conversion, but that's only used on the Wii.
