Power won't stay on my onkyo tx sr304

Onkyo tx-sr304 got slightly wet. I immediately turned the power off, unplugged it, disconnected all the wires, removed the top plate/encasement, dried it with a hair dryer and waited 1 hour. Following the instruction manual, plugged just the power cord in, turned it on and set the volume to max. It stayed on about 3 seconds then the protection/ standby kicked on. What next or is it even worth it?

SOURCE: Onkyo TX-SV434 "Protect" light

The protect mode is a built in safety message, indicating that theres a fault somewhere with-in the unit, and it wont let the unit come on fully or more damage will occour. This unit is a solid state device, and you should not attempt to use it or open it or try any self repair as it will cause more damage. If this unit is more then a few years old , it might just be the time to start looking around at all the back to school sales on electronics, as to have this unit serviced will cost an estimate fee as well as parts and labor. If you want to invest a few bucks into this machince , then go for it, but its most likly will cost 1/2 or more then the cost of the entire unit did when it was new to have it repaired. It is up to you. Good Luck

SOURCE: Onkyo TX-NR905 Protection Circuit Activated

The problem is not with the inputs. This unit is in protect because a problem has been detected in the output section. Try disconnecting the speaker wires and turning it on. If the unit remains on, there is a short in one of the speaker wires. If the unit still shuts down, there is an internal problem that will require repair. It sounds like this is a new piece. If so, it should be covered under warranty.

Keep us posted,
Dan

SOURCE: Onkyo TX-DS989 not staying on

This sounds like the action of some protection circuit that is monitoring some condition or voltage that isn't within its design limits. If it was mine, I'd look for an Onkyo forum to see if others have experienced the same problem.

My Onkyo TX-SR606 won't turn on


The reference to Zone 2 means that your Onkyo receiver is set to be remotely controlled from another location. Normally, this arrangement would be initiated at the time of set up but could be done later. You may have to repeat the initial set up routine to get things back to normal

My onkyo tx-sr605 7.1 a/v tuner will not switch from game/tv to cable/sat or any other mode. I can't even get into the setup moder It won't power on even if I press the power button manually.


You have this all backwards. So essentially it won't power on. THAT must happen before setup or anything else.

http://www.retrevo.com/support/Onkyo-TX-SR605-Receivers-manual/id/2526bh742/t/2/

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 'nekkid'. 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.

How to program remote control?


Your Onkyo TX-SR304 receivers remote (RC-645S) is not capable of controlling devices by other manufacturers. It controls only Onkyo devices.
Other Onkyo remotes do have universal remote functionality and you can download Onkyo remote codes here.

I hope that helps.

I have a onkyo tx sr304 and a onkyo 6 disc player dx-c390.When my cd gets to disc 4 and 5 it shuts the receiver down.Whats up with this?


The only possibility that comes to mind is that it may be causing a short somehow when the carousel gets to that position, maybe a broken solder joint. Another possibility is that there may be a foreign object stuck inside the player such as another disc that lost it's position.

Need codes for universal remote


Not sure if this helps, but I just called Onkyo with a request for codes for the SR304. They said the only codes they have are for THEIR remote. Maybe they will work with yours. Here they are:
0276 0476 0810 1187 1376.
I tried these in the Comcast remote (adding a 3 in front of the numbers) but that didn't work. Still trying to get my Comcast remote to program the Onkyo SR304 adequately, since their published codes only partially work.
