Only stand by mode is on

power supply in the unit is most likely or it is in shutdown because of a short----a owner manual is unlikely to help.

I have bought an ONKYO HTS-6300 from the USA (120V) and tried using it in India (220V) using a step down voltage converter. The receiver shows the red light but unit does not get on. It keeps on making a...

You have to use a step down transformer with this set and not a converter. The AC household voltage in Inda is 220VAC. Your set is designed to work on 120VAC. Therefore a 220VAC==>120VAC step-down transformer is needed to feed it. The onkyo has transformer inside, and it should get 120VAC; atleast 5AMPS current capacity. AN inverter cannot synchronised with this set. You can either buy it from Inidan electronics spare part market, of can be winded by expereiced transformer winders. Never give any inverter to this set, as some Onkyo models will have Torroid transformer inside, and it will take a tremendous amount of current at start-up, and make either your Onkyo of your converter to get damaged. OK.

My Onkyo S7300 receiver doesn't work, it makes choppy sound why it turns on

this may be the HDMI heat issue i've found with these amps. the issued is caused by the heat produced by the 5V voltage regulator under the HDMI board. once the sound starts to get choppy and or cutting out sometimes with a loud boom. the only way to get around is by installing a fan. First try using a 12V 4Inch fan place it directly on top of the amp cover over the HDMI board use a good Power adapter so the fan runs fast. Now IF it works! I suggest you install a Internal fan I have attached the picture for you to follow. the fan will not be as loud because the supply will be only 6 Volts. NOW TO AVOID THIS ISSUE FROM HAPPENING AGAIN TURN OFF THE HDMI CONTROL UNDER THE HARDWARE OPTIONS. HDMI PASSTRU IS THE MAIN ISSUE HERE. the regulator sits there for hours cooking that board. it's why half of Onkyo HDMI capacitors and regulators die out.Be careful do this at your own risk. High Voltage inside this amp. good luck.mvianna_0.jpg

I do not see any inputs to connect a subwoofer to my Onkyo A-9555 integrated amp. I would like to know if it is possible to connect it and what kind of subwoofer should I buy for that wit the best...

You amp has no OUTputs for a sub, but if you really want to attach a sub you'll need to get one that is self-amplified and accepts >>>stereo<<< High Level or Speaker Level inputs.

Otherwise your amp's volume control won't also control the sub's volume.

You would feed it full-range audio from the speaker terminals on your amp and its internal amp would use that to develop its own power output for the sub.

Here's one example.

Using An Onkyo Remote to control Sky+

Code that I have for sky + is: 01175. There are several other codes for other versions of sky boxes if you think you may need them but that should be the one.

Samsung has a huge code list: 10017, 10037, 10047, 10054, 10056, 10060, 10090, 10092, 10093, 10154, 10156, 10178, 10226, 10702, 10766, 10814, 11060, 11235. Unfortunatly you'll just have to try them one at a time until you find one that works. Hope this helps.

Bose PS321 No Sound

The power supply is 29 volts raw voltage,the IRFI44N fet on the power board is used is a switcher.
It reduces the voltage to 17 volts which is required for the AV3-2-1 meda center.The higher voltage biases the sound to cut off and can blow the drivers,try changing the fet and see if plays........
