Hi
i bought ta-e9000e from goodwill with no sound or picture . i just wondering if any one has an idea what is the fault.and i also try to download a software on it but ido not have the software version or a link to it my software is 1.1A .
THANK YOU IN ADVANCE.

Re:
I always look for back stk Ic's in these. not the outputs but in the output driver stage. copare voltages with the other stk's . Does one of them have higher voltages? Like instead of 1.3 volts it has 4 or 5volts? if so it's bad. you can find these Ic's on ebay , I did. also upc2581 driver ic's can do this.

Hi John. It can be fixed, and most probably relates to the power supply. There is a Sony repair doc that lists low or no display, but also associated with no audio.
Here is the information regarding the problem.
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 parallel 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.
If you still have sound, then there may well be a problem elsewhere. It is a great Preamp, and I recommend you get it fixed. A Sony Authorised service center would be the best place to take it. They supply good inside information about this most problems that occur on their gear. There is good info on your preamp controller here

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.
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.
