SOURCE: Yamaha RX-V995 receiver turns on & then powers off 2 seconds late
I suggest you run self diag. press [FM/AM] key + [Input mode] key and press the [power/standby] switch.
ps prt = power supply problem
dc prt = shorted output or leakly cap in channel
tmp prt means to hot on heatsink
you'll likely have to measure the resistances of the output FETs to find a short,

Hey, yeah that can be frustrating.
When you turn it up do you hear the relay or a clicking sound, then you turn it on and it comes back below the +2db?
Try unplugging All the speaker wires from the unit. Turn on the unit and listen for the click.
after the click, turn it up past the 2+ db mark and see if you hear it click or shut down. If it did not click off, then suspect a shorted crossover on one of your speakers.
2nd test is to plug in One speaker, and test it at high volume, it will not harm it. If it shuts off disconnect that speaker and try another. Only one at a time.
If it works at high volume, you need to isolate one of your speakers and i bet it has a shorted crossover that has been cooked. P.S. If one is bad, suspect they will fail at a later date.
If they all fail, use a friends speaker and try it before sending it to a repair shop.
P.S. i found one on ebay i think you can get for under $100 bucks in the box.

Make sure you have an analog RCA audio cable from the source to the receiver. Digital coaxial or optical will not work for zone 2 or zone 3. By adding an analog cable it will not affect your main zone, it will always go to digital first. Hope this helps
