Thank you for checking.
Unfortunately, the issues you are experiencing are symptomatic of an internal hardware defect, meaning a faulty power supply or main/control board, though there are many possible failure points. This issue could be a manufacturing defect, but is also often caused by a power event (shock/surge, prolonged over/under voltage condition, etc).
This could also be the result of age related wear and tear; as a 2006 model, that type of failure wouldn’t be surprising; this amp is at twice its designed service life at this point.
There is one further step you can take here, both as a possible fix, as well as a diagnostic evaluation:
1) Unplug the power cord from the outlet
2) Wait at least 1 hour (60+ Minutes)
3) Press and hold the power button (on the set, not the remote) for 60 seconds
4) Keep holding power button while plugging back in, and for another 60 seconds after. When plugging back in, go directly to the wall outlet, bypassing any power strips or surge protectors.
If this reset process does not work, it would unfortunately confirm an internal hardware failure.
This is something that would require repairs to correct; however repairs for these units are generally not practical. There are no parts available for them any longer.
If you’re considering repair at a local shop, you’ll find a typical repair to be around $300-400 for diagnostics, parts, and labor.
For an amp of this age however, replacement will make more sense. You can get a brand new receiver with a fresh warranty and updated features (hdmi, networking, 3d, 4k, etc) for the same price or less than you'd spend on repairs.
Depending how you’d like to proceed here, I can help with finding a repair shop, or recommending replacement options. Just let me know.
