Hi there, RikSound1. The problem is the C657 capacitor, located on the DSP PCB. It's a 0.047 farad capacitor, 5.5V. You can either replace it yourself, or just hand the info out at your local repair centre ! It will fix the problem for sure, i have fixed that problem already. Thanks, cheebster.

Wow, general problem here, but the most near your problem could be, power failure, or the Power adapter is bad, or a energy failure at home, time to buy a new adapter.

To avoid making the avr go into protect mode when you power up your Hafler 4000 that is connected in the avr's pre-out, you must power up the set up in the correct sequence.

1. Turn off your avr
2. Connect Hafler 4000 to the avr's pre-out it it is not yet connected
3. Turn on your Hafler 4000. The avr will not go into protect mode becasue of the transients from the Hafler because it is still not powered on.
4. Turn on you avr. There should be no more transients from the Hafler at this stage unless it is not functioning correctly, so the avr shouldno longer go into protect mode.

Hi and welcome to FixYa,

Appreciate the direct "Ask Me".

Initially, pls try cleaning the battery terminals. In some instances, it may be necessary to scrape them to remove corrosion. Still there are times they may have to be bent or stretched to ensure that they provide more pressure to the batteries. Alternately, pls try to confirm that the AC adapter is working by checking for the presence of voltage on the plug/connector with the use of a voltmeter.

Should the above not address your concern, then it is most likely that the problem is internal electronics and the unit is simply going into protective mode. You then have a choice of performing a DIY (do-it-yourself) or seeking the services of a qualified professional.

Good luck and Thank you for using FixYa. Happy Holidays.
