My onkyo ht-r590 goes on then shuts off right away.

The amp protection circuit has been activated. Remove the power cord from the wall outlet immediately. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect the power cord and reconnect an input and a pair of speaker wires onto the unit. If the receiver still does not turn on than you will have to bring it in for service. Turn up the volume and if the receiver doesn't shut down, power off the receiver and add another pair of speakers. Power up the unit again and turn up the volume. If it doesn't shut down, power off the unit again. Now connect all your input sources and turn on your receiver. If the unit shuts down again, your unit will need to be further serviced at an authorized Onkyo service center.

Red light is on in the back of my t300 tower speakers

That is the standby mode but if its not kicking out of standby mode it could be a fuse issue

The T300 uses a 2.5A fuse.

To replace the fuse:

1. Unplug the AC cord from the AC power source,

then remove the AC power cord from the speaker's

power connector.

2. Remove the fuse cap with a small, flat blade screwdriver

(see diagram 2).

3. Remove the fuse from the fuse cap

(see diagram 3).

4. Replace the fuse inside fuse cap with another metric

5X20mm size fuse

5. Replace the fuse inside the cap, replace the fuse

and cap in the power connector (see diagram 5).

6. Connect the AC power cord to the speaker and

raise it upright.
7. Connect the power cord to an AC power outlet

Page 42:

No sound. The system cord and/or speaker cord is not connected. Check the connection.

The audio cord is not connected to AUDIO IN (VCR)

and/or DIGITAL IN (DBS) correctly.

Connect the cord correctly. (A pg. 13)

An incorrect source has been selected. Select the correct source. (Apg. 17)

The decode mode is not set correctly. Select the proper decode mode. (A pg. 35)

Do you think the powered subwoofer itself might have a power problem? Check its cord.

MOst of the time it is the jack that the cable plugs into that has the problem. .
Also the jack is not broken but HAS broken the solder connection TO the jack.
If you know someone who can safely take it apart and solder, let them try.
