What is the output voltage of my 230vac tranformer, the outputs from it go to a pcb and the output votage from that is 15v/1A/15w. i need to replace the transformer but need to calculate the voltage output from the tranformer to the pcb Ac inputs first, ps the old tranformer has no output as it has a short..thanks

You can't couple AC (from transformer) to DC (from a battery)..you will have lots of fireworks if you try

1. No transfer charging. A. The connector terminals of the high-voltage PCB make poor contact. Reinsert the connector. Also check for continuity within the connector cable. If none, remedy or replace the cable. B. Defective engine PCB. Replace the engine PCB and check for correct operation. C. Defective high-voltage PCB. Replace the high voltage PCB and check for correct operation. 2. No LSU laser is output. A. Defective laser scanner unit. Replace the laser scanner unit (see page 1-6-29). B. Defective main PCB. Replace the main PCB and check for correct operation. 3. No developing bias is output. A. The connector terminals of the high-voltage PCB make poor contact. Reinsert the connector. Also check for continuity within the connector cable. If none, remedy or replace the cable. B. Defective engine PCB. Replace the engine PCB and check for correct operation. C. Defective high-voltage PCB. Replace the high voltage PCB and check for correct operation.

Sorry Gregory, gave you the wrong number.
You could try something like this. Various voltages and currents with different adapter plugs. This is on Ebay UK but I would think there are others, don't know where you are.

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.

I know this is a little late, but the power supply that these speakers use appears to be 5mm across. The output specifications are 15V DC, 1000mAh (1A), with the center pin being negative.

The power supply is Logitech Model # GAD-SLU-240A8 P/N 190057-1000 OUTPUT IS 24V-----0.75A The output connector is positive center, negative outer ring.

use drop down tranformer makesure you have the CORRECT voltage output

ahhh the noise maker comes to life again .. Ok my friend this is a common problem with this set If your lucky?? If you know anything about trouble shooting tvs then this is what ya got.. Try first to measure the Horizontal output transistor. It will meaqsure a few ohms between the base and emmitter. But the base and collector should measure about 450 to 550 olms on the diode settings onm the metter.if it measures shorted you need to replace the flyback tranformer along with the Horz output transistor. Now if the HOT( thats horiz output transistor)is not shorted then theres a little coil in the horizontal drive thats causing problems as you need to take out the coil from the PCB and scrape off the ends and reinstalkl it. also the horizontal driver tranformer as well as the resistor that feeds the transformer could be bad and thast is a 3200 ohm at three watts. if ya dont have a clue what I just said the sets gonna cost ya ariynd 200 to 300 to fix .. Is it worth it to ya>?????lol Good luck
