Question about Sony TA-E9000ES Amplifier

4 Answers

Sony TA-E9000ES Amplifier seems dead

This pre-amp was working just fine, then started making popping noises sporadically. Power off/on corrected that for a while. But now it seems dead except for orange light behind the - + mode button. Pressing the other buttons in the same row (auto-format, 2ch, audio split) will light up, but there are no other indications of power; no light on power switch, display or any other sign of life.

Does anyone know if this might be a repairable problem ?
Appreciate any suggestions...Thanks.

Two things:

1) Yes it should be repairable.
2) Please confirmn the model number.

With the model number, I can verify the circuitry and provide you with better guidance on the repair process.

Thanks,
Dan

Hi and welcome to FixYa,

Initially, your description of the original/start of the problem could possibly be capacitors discharging/charging or just dying out. The description of the current status leads to a probable power supply problem. Thoough the indication is the absence of some of the rquired voltages, it is also possible that the system is in protective mode hence the voltages are not allowed to go through. This is due to possible component faults that draws excessive current.

This would require that the unit be opened up for a looThis of course would require a fair familiarity of electroniccomponents/circuitry and safety procedures, use of a DVM and asoldering iron. It would be to your added advantage access to a servicemanual or at the very least a schematic diagram with voltage readings.Should you be uncomfortable performing a DIY (do-it-yourself), perhapsyour best bet would then be to seek the services of a qualifiedprofessional.k & see.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Hi guys. Having a problem with my NAD T163 Surround Sound Decoder. Popping in front left and right speakers when changing audio selection. Works well other than that. Please give me some suggestions w


Could be DC voltage on the speaker output line, but this will generally keep your receiver audio output turned off completely. Could be a bad muting transistor or microprocessor IC(computer within your NAD). If you are interested in having your NAD repaired, please visit my website at audioserviceclinic.com.You may contact me there. Thank you..

Power on but no led display


"Power board:
The power supply is the main culprit for most of the TA-E9000ES failures. Symptoms of this are no sound and a very dim or no display. Apparently the power board has several weaknesses which have caused Sony to supply a modified version in later production units. The circuit around transistors Q108 and Q109 are prone to oscillation, which will cause one or both transistors to break down, as well as resistor R124. This resistor is originally a surface mounted device capable of 1/10 watts of heat dissipation. The modification suggested by Sony is to replace this 4.7 k ohm resistor with a 1 watt rated version. Also, to prevent further oscillations a 100 pF capacitor is added in parallell with R153. (Some suggests that also transistor Q110 is a candidate for replacement.) The US issued service bulletin from Sony suggest that this fault may occur with units having a serial number in the range 800001 - 802746.
Serial numbers 80#### are for the US/Canadian version.
Serial numbers 50#### are for the european version."

Zone B of Sony amplifer seems to have stopped sending most of signal


Hi, please have a look at your supply. The voltage might have gone below 21V on your newer models and 42V on your older models. This you will find near the pre-amp. Look for 2 big Cap's and start from there.

TA-N9000ES Amp - Standby light constantly blinks - no sound


The flashing light is indicating that a fault has been detected, and it is staying in "protect mode". First disconnect all cables from the processor (except the power cord) and then power up the processor. This will eliminate the possibility of a shorted cable or a problem with any connected components. f the light still flashes, there is an internal problem and the processor will require profesional service.
