content: My Onkyo receiver works perfect at times and then it just stops producing sound. Any suggestios?Seems to me that it is an easy fix but I'm not too handy electronically.

content: Quote from: Eldo on February 28, 2025, 10:40:01 pmThere is zero chance of you fixing it if you can't give more info than that.Does it go completely dead with no signs of life such as no LEDs or display alive? Any hiss or hum from the speakers? No sound from any input?There are dangerous voltages inside. Are you competent to open it up?

content: It's an Onkyo HT-RC180 AVR. I took cover off and felt around for loose connections. Everything is all connected as far as I can see. All led's light up and all buttons are in working order. No I don't know anything about working on these. I probably shouldn't even be sticking my hands in there but I thought something might just be loose. I bought it on Ebay and was told its in excellent condition. Was working fine and no dents or scratches anywhere. I'm just hoping someone could possibly know what might be going on. When it works, it's perfect, otherwise there is no sound whatsoever.Any suggestions would be greatly appreciatedBill

content: CAUTION: Don't risk harm or additional damage if you are really clueless about electronic devices and circuits.One thing you can doif you are careful: poke around with anon-conductingrod (wood or plastic) and apply pressure to various parts and locations to see if you can locate a sensitive area. If you do, then remove power and carefully inspect to look for bad solder joints, loose connectors, sockets, cracked circuit boards and the like. Capacitors can store a charge, by the way. So even un-plugged, there could be energy lurking!CAUTION: Don't risk harm or additional damage if you are really clueless about electronic devices and circuits.

content: Ok thank you for the feedback.......much appreciated.I'm guessing something might have loosened during shipment from California to Florida. It was packed perfectly but you never know what could happen on the way.Thanks again,Bill

content: Bill, I just love my old Onkyo amp and Tuner.. those are very solidly built. I have repaired the amp several times, but only had to clean some switches..With mains unplugged, please make pictures of the interior from different angles, overview and detail..Maybe we can detect the flaw, with our combined electronics experience.Frank

content: If the sound just stops but it otherwise appears ok, it could be that the DSP is bad. This is a pretty common issue with Onkyo and other brand receivers. If it has the symbols for L C R on the display and they disappear when the fault occurs that will confirm it. You can try the 5.1 (6 channel) input if it has one as that doesn't normally need a working DSP to produce sound.

content: Wouldn't really know, but is there any sound from the headphone jack?

content: I didn't feel comfortable poking around the inside. I was hoping it might be something obvious. Yesterday I found a shop that does these type of repairs. To me it seems it'll be something minor but what do I know. As soon as I hear back from shop, I will follow up with results.I truly appreciate all your feedback.Bill

content: If it was in good operational state before shipment, it probably got a bad hit during shipment and some PCB trace or electronic component is now broken with unreliable connection. My father used to locate such errors tapping at PCBs and components like Grandchuck recommended above.Somebody with experience will then be required to fix the problem once you know what it is, soldering in some bodge wire or replacing a faulty component.Regards, Dieter

content: Got my Onkyo receiver back from shop yesterday and was told it was a "ball chip" whatever that is. I believe he said it was on the HDMI board. Anyway, it's all good now. Just want to thank you all for your feedback again.Bill
