Question about Sony STR-DE675 Receiver

1 Answer

Amp making clicking noise at varied times

My receiver is 5 years old, it has just started to make clicking noises at different times and at different volume levels. It could be 10 minutes or 30 minutes etc, it is the same noise that is made when the amp is turned on. I have not lost any sound when this happens and sometimes I get a small power noise in my front speakers, i have checked all connections. I have been looking around for a new sony 5.1 receiver but the STR-DG510 is the only receiver in a 60 mile radius of my town and does not have all the connections the 675 has. Maybe because it is $200 cheaper then mine was. Thanks for and help with the clicking noise.

    I have the same problem with my Sony STR-DA555ES. It is a faulty power relay and needs to be replaced. Will advise after I get mine repaired.

Hello, headbanger here again. I have fixed the amp myself with 3 relays from an electronics company, the number on the relays can be seen by taking the cover off. The three speaker relays are at the back of the circuit board, there is a fourth relay for the power switch but it is at the front of the board. I did replace all three instead of the bad one as it was only $2.68 for each relay. The most important thing is the pin spacing on the relays, there are different relays that do the same purpose that have different pin postion, they will not fit into postion as the pins are only long enough to fit exact.I live in Canada and a company RAE Industrial Electronics Limited at Burnside Industrial Park in Dartmouth, Nova Scotia ... Their phone # (902) - 468 - 1238 ... Fax 902-468-5887 ordered them in. The part number on the receipt is ALA2F12 - RELAY,DPST, 3A 12VDC .. The sales order number on the receipt is 43771-2. Well that's about all the info i have, hope it might help with someone else. Paying $10 to fix my amp was well worth it, having a friend at work with electronics experience helps alot too. He did all the leg work for me to find them, bought him a dinner at work for his effort. My dishes at home are rattling again. OYEAH.

Car wont start

First clean all battery terminals ensure there is no corrotion, after cleaning them light coat with a dab of grease to protect from further corrosion.

Although the lights may work, the battery may not have enough power to kick the starter over.

Since you specified no noise, suggest you check the starter solenoid first. Ensure the battery is good and holding the charge.

Ensure your alternator is working properly. May not be charging the battery.

Loud humming noise as fridge is running

Sounds like the freezer fan is rubbing some wires or possible some foam insulation around the fan. I would look into the freezer compartment fan and go from there. The fan Will Shut off when you open the doors. Let me know how you make out and if you need anymore help.

Losing volume on channels

I am afraid not. That crackling is a component in one of the solid state amp circuits starting to fail. These are all soldered into the printed circuit board. This could be a difficult repair to find an intermittant component. Depending on how old the unit is and how much it cost will factor in on if you have it repaired or not. Rule of thumb is that if the unit is two to three years old and cost less the 200 to 300 bucks you should not invest more then 100 to 150 bucks into it. Good Luck
