Denon AVR-2310 – No Audio

The Denon AVR-2310 was $30. The symptoms were no audio, but all else works fine. I tried a CD and DVD, the display indicated the change in detected audio formats, but there was no sound. I would have tried the tuner but for some reason there doesn’t appear to be a way to change source to the tuner unless you have the remote. I removed the top cover and used an air compressor to blow all the dust out. I read online to pay particular attention to the headphone jack when there is no audio. Put it back together and it started with no issues. Watched a few movies and the sound was excellent. I do note it wasn’t very loud until I turned all the filters off like Dynamic volume, Dynamic EQ and Audyssey… Read More »Denon AVR-2310 – No Audio

Yamaha RX-A740 – Power issues

The Yamaha RX-A740 was my first real electrical challenge that wasn’t already published online. It took the longest to fix, and I ended up buying 2 additional Yamaha receivers for parts. Purchase price was $30. Technically: +$10 +$20 for the additional receivers but more on that later… This receiver was hit and miss – it could work for an unknown amount of time or not work at all. To diagnose it, I made sure it was off and drained of power, reconnect power cable, hold Tone Control and Info, then press power/main zone. This displayed “PS3 PRT:131 L”, then turned off. After consulting the service manual (very easy to find). Sometimes I’d get 5-10 minutes before it died. I ran heat test to see if it made it worse. It, infact did not, and when… Read More »Yamaha RX-A740 – Power issues

Pioneer SC-2022 – EU22 Error

The Pioneer SC-2022 receiver was the first of many audio receivers I’ve purchased broken and then fixed.The fault of this receiver was “intermittent audio”. When I picked up the amp, it was very clean with remote, manuals and setup microphone. It was also the most expensive at $50 AUD. The unit powered and ran fine for the first day, then was moved into the TV cabinet. It was this movement that triggered the instant stopping of all audio and displaying the error “EU22” Thankfully it’s a fairly common problem and I had researched the symptoms before I bought it. If you search the internet for Pioneer and EU22 you’ll find many posts and the solution most of the time is to go at the DTS chip with hot air gun. The hot air gun I… Read More »Pioneer SC-2022 – EU22 Error
