Onkyo TX-SV444 problem

Hi! I have an Onkyo TX-SV444 A/V Receiver. I have had this receiver for about 12 years.One day I noticed the receiver kept cutting off after about 3 or 4 seconds. After a couple attempts of turning the receiver on, it just quit working. After checking the speaker wires, I noticed 2 wires were touching, which probably lead to the stoppage.I have checked the fuse and it appears to be OK. Others I have talked to said it sounded like the protection circuit has gone bad. Do you know where I could get a new circuit?Thanks, Tim

Hello. If the wires have touched, your amplifier probably has what's known a DC Offset, meaning a damaged amplifier. You will need a qualified audio tech to repair this, as this type of forum is not designed for detailed step by step repair.

Sorry.

The shorted spkr wires probably fried the putput transistors in that channel.  Do you know how to use a Fluke  test meter on diode test

I have an onkyo tx-sr308 and I am receiving only static or very low music on my right speaker channel. Please help


Switch to the other set of speaker outputs (move from A to B). If it continues, you have a repair issue...assuming it happens with all inputs. If it only happens with DVD, or CD, or Tuner, or whatever, but works fine with other components, it's a connection issue - unplugging and replugging, or replacing cables may correct.

If I recall correctly, that unit doesn't have a standard twist knob style balance control. If it does, turn the unit off and rotate it through it's full range several times, then recenter it and try listening to it again.

How powerful loudspeakers can my Onkyo TX-SV444 tackle, maintaining good sound?


buy 6ohms or 8 ohms speakers. 4ohms consume too much power and sometimes causes short circuit. (safety first!)

Volume on my Onkyo Receiver


Yes it is. I have the 705. My room mate has the 605. Both AVR's will not have appreciable volume until 50 on the dial.
The dial in not linear. I don't know of anyone who has plotted the scaling of the volume control yet.
I have found much useful user info on avsforum.com. Owners post Q&A based on experiences.
Search the forum for "official onkyo TX-SR605" thread.
Some comparable info may also be found under the "official onkyo TX-SR705".

Onkyo TX-SR304


Onkyo offers access to manuals at their web site. HERE is a link to the receiver line.

Personally, I'd connect the speakers to main left/right. The subwoofer to subwoofer out. The Go VIdeo unit to VCR/Video 1, the cable box to Video 2 and the video output to the Sony TV composite input. No need to connect the TV audio out to the receiver since the audio feed comes from the cable box.

No Sound


Called Onkyo and here is the solution they gave me.

1. Turn on unit.

2. Press and hold VIDEO 1 button.

3. While pressing VIDEO 1, press Speaker A button.

4. You should see "CLEAR" on the display for a second and it will go on stand-by mode.
.
5. Turn on the unit and check if sound is back.

Hope this helps
