Question about Sony STR-DE545 Receiver

Reduced audio output from right channel

My Sony STR-DE545 receiver's right channel, both front and back, A and B, started outputting audio @ less then half of what the left channel does. Does anyone have any idea on what could be causing this?

Re: Reduced audio output from right channel

Try lightly tapping on chassis to see if you can get audio to cut on or off with vibration if you can most likely cause is bad solder connections. This unit is well known for poor solder connections especially around poweramp driver IC's IC701, IC501. Also Electrolytic Capacitors in unit have fluid in them and heat Evaporates the fluid causing them to not operate properly over time . Caps that usually go bad are around parts that run hot like Power amp drivers
Just a couple likely suspects.
Try unplugging overnight to give unit a Good Reset also double check all setup settings.
If you need service manual I may be able to get you one

Str-gx800es sony receiver problem- right channel speaker sound is 'static', low and distorted. I have checked checked all speaker and output/input source cable connections with no luck. All left channel...

If you have checked the speakers and wiring, the right channel has a audio driver or output problem, which explains the low volume, static, and distortion. A service technician will be required to fix the receiver so it will balance the left side.

The receiver works ok until the vol is reduced and the right front channel drops out. Increasing the vol usually picks up the dead speaker but it drops out again when the vol is reduced. I've tried...

Make sure the audio level on the left and right channels are balanced. Check the menu for audio levels to adjust and make sure they are not maladjusted. If all levels are adjusted properly then the volume control or volume control circuity may be at fault.

Most likely it's due to bad solder for the Blue Relays.It can be fixed by re-soldering.

The Output Volume Is Extremely Low!

Sometimes the rear channels can be used as a 2nd zone. Does the unit have A&B speaker selection on front panel? Usually if it has a 2nd zone it will say in owerns manual or on back of unit or on front panel as well. That is when you have the option to adjust the volume in the menu on the 2nd zone. GURU JAY
