I have 2 questions will my SONY TA-E9000ES preamp work with my SONY STR-DG720 7.1 RECIVER and what SONY ES Amplifer was spefically made to work with the TA-E9000ES WHEN IT WAS ORIGANLY PRODUCED

Are these parts unique or are they connected with one channel?

If they are connected to one channel, look at one of the other channels for the same types.

Go to www.sony.com contact customer support and the technical department to see if they can help, also try www.ebay.com type make and model and go through the list if available.

Try the Sony consumer website or a place call mrremote (dot) com

also replace Q108 @ Q109 on power board. If that does not fix it then also replace PH101 & PH102. Also on Power board.

try to connect all your cables again but step by step and make sure you connect it in the right way and correct location of every cable.

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

Serial numbers 80#### are for the US/Canadian version.
Serial numbers 50#### are for the european version."

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.
