What is the voltage output for this Transformer they are 4 different variants 6v 9v 12v and 15v. Ive looked at the service manual on line and it only tells you the input voltage ..being 240v, not what comes after the transformer.

2.power transformer .
3.fuse (if have)
4.rectifier (dc cct)
5.input voltage to transformer.220v ac or 110v ac.
6.output voltage from transformer .(low ac value 12v 9v 7.5v....)
7.voltage in smoothing capacitor.according to transformer voltage 12v,7.5v etc....
power switch and switching power.
There should be a small white ceramic block on the firewall - this component cuts the battery voltage from 12 to 9 volts for the coil and ignition system. It has 4 wires and is called a ballast resistor. You may need a book with the wiring diagram to be able to test it. You should have battery voltage going in and something like 9 volts coming out. You can also run a wire with a fuse from the battery to the positive side of the coil to check the system. Disconnect the factory wire from the coil first.
Information from Sony: Audio Output Error (6X) There are three possible failures that can cause a 6X protection mode, and they are as follows. • Short Audio Amplifier Outputs • Lose of 15V Supply • Lose of 9V Supply The key to determining what to check first is if audio is heard before the TV shuts OFF. If audio is heard before the TV shuts OFF, then the next step is to check the 15V supply at CN7503/pin 1. If the voltage is missing replace the G1/G2-Board. If the voltage is present, first check the fuse PS7001 for a possible easy fix. If the fuse is OK replace the AU-Board. If no audio is heard before the TV shuts OFF check for 9V at CN9502/pin 1. If the 9V is missing replace the BU-Board. However, if the 9V is present check and confirm that the protection circuit output voltage is making it to the Main Microprocessor IC1001/pin 26. If 2.8V is present at IC1001/pin 26 then the Main Microprocessor is defective. Replace the BU-Board. If the voltage at IC1001/pin 26 is 0V then the audio output circuit has actually failed. In this case, replace the AU-Board. A shorted audio output or a DC voltage level measure across the audio output will cause a 6X protection mode indication. In either case the problem will exist in the audio circuitry on the AU-Board.
Look at the old adapter if you have it. Match up the voltage requirement. and meet or exceed the current (mA) rating. also make sure it is DC if required. Any adapter that has the right voltage and current output will work. Also you can go over the voltage but like 20% ie: 12V works for 9V, and 15V works for 12V and so on. But if you go under the voltage requirement, only do so by 10 percent. And increse the current requirement proportionally. Chances are you have an old adapter around that you are not using. If you need to change the connector, the wire with the white stipe on it is usually positive. So long as you match them up you should be ok.
method 1: buy a power adapter that has a switch controlled output voltage - they usually have 3V - 4.5V - 6V - 7.5V - 9V and 12V selectable output. Start with 6V and if its not working unplug, select 9 and try again etc. etc.
method 2: open the case and locate an electrolytic capacitor right near the power plug - the biggest one. Note the voltage (for example it may say: 1000uF/15V) and have in mind that your device MUST work at a LOWER level that this.
The trigger voltage of the 45CL-1 is about 12V, so it should be safe to connect directly to the hot shoe with an adaptor, or to the pc soclet, if the D90 has one. If the D90 is anything like my Canon 40D, which can stand about 30V on the hot shoe, then all the 45CL series will be ok, as they have trigger voltages between 9V and 12V. The 45CT-5 has a trigger voltage of 15V and works well on the 40D. I use 3 different Metz 45 models with my 40D and all work well on automatic, where the flash sensor itself controls the light output.
