Thanks for the vid my friend. I have a yahahaha RX-V381 that if theres a power outage or its unplugged it "Forgets " what it is..And I have to hit a series of buttons to remind it that its a RX-V381 from USA.. After that it works fine..I have a large set of DCM Timeframe 600 speakers that are rated at 6 ohms. If I crank up the volume to a pretty loud level it shuts off... Any idea what could be the problem? Im thinking maybe the emitter resistors are bad or have ring cracks, or maybe I need to recap my crossovers in my speakers..?
I'm not sure if the Yamahahaha units have a CMOS battery for settings like you mention. If yours seems to have one, it could probably need replacing. As for your issues with your speakers, I would check the impedance rating on the back of your unit. It could be that 6 Ohms is too much for your amplifier to handle. Or, if it is the case that your amplifier can handle that kind of load, I would start by checking the main positive and negative rails for the power amplifier section. If they are not in spec, your amplifier might not be operating at optimal performance.
If you still have it, is there any chance that you'd be willing to sell the digital board from that RX-A730? I just bought one and the guy who had owned it actually burned the PCB while trying to "cook" that bad IC.
