Question about Sony TA-N9000ES 5-Channel Amplifier
My Sony TA-N9000ES 5 channel Power Amplifier is down, when turn on the amp, there is no click sound and the red light is flashing continuously. I've contacted Sony service and it indicated that the unit is no longer in warranty. To have it services, I have to ship out the unit to TX. If some one could point out for me a problem or help me to locate a service place in the northern CA.
Thank you so much..
An amp of this size generates alot of heat internally when in use as these use mosfet ICs and can get very hot.
your problem is most definately dry solder joints and possibly quite a few at that.
i've repaired quite a few sony surround receivers with similar problems and have all been down to dry solder joints.
hope this helps.

Register and download the manual for free audio.manualsonline.com
Set the BTL/Normal switch on the back to Normal. In fact, any switch or knob with BTL, set it to whatever choice is NOT BTL.
