How do I set up receiver

Hello, we have a problem
Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
Check for loose speaker connections at the speaker as another possible root cause forintermittent shutdown.

When I turn on the receiver it flashes the word
The most common problem found on FixYa for Audio Video Receiver's is:
My
receiver say's "Protect" or turns on then off. What's wrong? Seven
times out of ten it is a shorted speaker or speaker wire. To
determine your exact problem, the first step is to disconnect all
speaker wires "at your receiver" Next: Turn the receiver back on. If
your receiver still says "protect" or turns off, it needs to be
serviced. If your receiver stays on; reconnect your speakers one at a time and power back
up after each speaker. You may find that after reconnecting all speaker
wires it works! Most commonly the small braids of wire from the + to the
- have touched and have caused the problem. In some instances, you
noticed the problem only when turning the volume up. either way, make
sure the exposed wires to your receiver are no longer than 1/2" long and
are completely under the screw down terminal or slide in.
When you've found the wire or speaker with the problem, your receiver
will go back into "protect" At this point, disconnect the wire from the
speaker at the speaker that may be causing the problem then test again.*
Note* Make sure speaker wires do Not touch each other as this Will
cause a short! If you turn the receiver back on and it stays on, you now
know the problem is in your speaker itself. To test your speaker, you
will need a multimeter. Set it to ohms resistance and touch the speaker
terminals, if there is a short internally the meter will read "1......"
If it's an analog meter, it will peg to the right. There's your problem.
Now, within any speaker there are quite a few possibilities as to what
could be causing the problem. Most common is a blown coil and the
speaker needs to be replaced. Some speakers have
internal crossovers (usually floor standing speakers) and may have a
shorted or burnt board (usually very visible brown burn marks on the
board) and can possibly be repaired if your handy with a soldering iron.
Now, if you disconnect the speaker wire at the speaker and it still
says "protect" Check your wire for the obvious cut or nail thru
the wire if possible. If your system has wiring that runs
behind walls, you may need to use your meter again. Disconnect the wire
at both ends, keep the ends separated, put your meter on ohms resistance
and touch probes to the + and - wires at one side. If the meter pegs to
the right or reads "1...." the wire is shorted and needs to be replaced
or repaired at the short. Hope this helps.
Speaker output shorted no sound and hot
You should see the damage to the part (perhaps even smell it too) which will need to be replaced. I suspect it will be on the big heatsink and perhaps connected to the channel which was shorted out. Check the internal fuses too.
Sony STR-DB1070
Check all your speaker connections and make sure there are no shorts where any of the negative wires can come in contact with any of the positive wires.
Volume change, followed by slight static playback.
I believe you have dry joints in output drive it require a qualifier Technician the do this you need special soldering station with anti static you are dealing with surface mount components if you shorted some thing in output drive it could damage to the output they are expensive to replace, now is not too bad you should bring in to Sony or servicce center Sony to repair it
