SOURCE: I HAVE AN ONKYO TX
The symptom you described can be caused by any number of things. I always start with the output power transistors which are the first things to blow with a speaker output overload condition. Unplug the power cord to your unit, remove the top cover and use an ohmmeter to check resistance from C to E on all 10 of the power transistors (Q6050 thru 54 and Q6060 thru 64) attached to the large heat sink. Blown transistors typically read <1 ohm, compared to good transistors that are >10k ohms. If you find a bad transistor it will need to be replaced.
SOURCE: The unit does not work
check the standby power supply first and then the main power supply.also check the output transistors and fuses your problem is in one of those points, normally the standby transformer goes bad, it is the small one right next to the big one.
good luck
SOURCE: humming noise through surround sound
This a problem of input grounding,the cable input is already loose or crack solder that why you hear a hum or distorted sound because not properly grounded it is a loose contact already thats why also is need to warm up and it will come.First change the cables with a new one with identical size and value then if problem still exist open the back cover ,when open look for the cable input connection parts joints reworks or resolder all soldered joints there .Then checks if it works then cover the unit.If you have no knowledge of electronics dont attempt to open to avoid electric shock.Find a electronics repairman or bring this to a authorized electronics repair shop maybe it cost you only $50.
Good luck;
Dont forget to rate...

SOURCE: can't get surround sound when watching tv
just dont put the jacks in from the tv plug satelite jacks in (use optic cable) dvd use orange digital cable and so on if u do it this way and have the same issues then i would 100% say its a reviever issue
(hope u kept the recipt)
