Andre28 Posted March 6, 2018 Share Posted March 6, 2018 So have had this problem with my 740a for quite some time. Basically one channel often drops out, or does not play on start up. Turning the amp off and on again fixes the issue about 50% of the time, but often it will drop out again. Usually the right channel, sometimes the left. Very occasionally both. It is about as intermittent as a problem as you could imagine. Headphones connected to the amp works perfectly, so I do not think it is the DAC. I have tried different speakers and get the same problem. I know this range had its share of quality control issues, so hopefully someone might know where to look (an electronics place looked at it briefly but could not pinpoint the problem. Further investigation likely to get pricey. Link to comment Share on other sites More sharing options...
Mungbean66 Posted March 12, 2018 Share Posted March 12, 2018 Could be a few things. I would think it was the protection circuit but you really have to have a poke around to know. Do you get a error message? This may tell you exactly what the issue is. Link to comment Share on other sites More sharing options...
Andre28 Posted March 22, 2018 Author Share Posted March 22, 2018 Sorry completely missed this reply. No error message. Currently it is back at the repair store, so see what happens I guess. Link to comment Share on other sites More sharing options...
