Hercules ProphetView 720 Power Adaptor Polarity

I have lost my LCD screen power adaptor in a move and need to replace it with another one. I have a power adaptor from HP which has the same specs, 220V AC to 12V, but am not sure of the polarity.

Is the (+) on the outside of the connector and (-) on the inside or vice versa?
I have surf the web to find this info but did not managed.

Thanks for your support,

Theo.

    For anyone else's potential interest, I finally found the polarity of my Hercules ProphetView 720 Power Adaptor.



    The Inner pin of the connector that fits into the bottom of the LCD screen is the Positive ( + ).

    As such, the outer part of the connector has to be the negative ( - ).



    In case you have to buy a replacement power adaptor for such a ProphetView LCD screen from Hercules, now discontinued by the manufacturer, output has to be 12V and above polarity respected.

Yes the adapter must have an output of 12vdc AND rated for a least 4.0A output!

Power failure?

First check the power supply / adaptor to ensure this is working correctly. Measure the voltage using a multimeter - if this is correct move on ( if not replace power supply )

Does the keyboard work if you hold the plug in the socket or move it slightly ? If so this is a common problem as the power socket on the pcb fails at the solder joint and will need to be repaired / replaced.

If this appears to be solid then you may have done some internal damage by either plugging in a power adaptor with a too high voltage or wrong polarity. If this is the case you may have blown some circuitry inside which controls voltage regulation.

Please report more if you have more information.

I have a Yamaha PSRE413. on/off does not work with adaptor, but works with batteries


If you are using the correct adaptor then the most likely reason is that the socket where the adaptor plugs in has broken away from the circuit board and will need to replaced/resoldered.




if you need a socket Google : Yamaha PSR power socket ( KPA3 / PA130UK / EPA3 ) (LB30226R)


OR if you have used the wrong mains adaptor and the polarity was reversed you may have damaged the diodes / voltage regulator on the power input.

Power light comes on but nothing else works.


There is a possibility that your plug on the adapter is the wrong polarity. See if the polarity is marked on your mixer by the power adapter jack.

Missing power cord/adaptor


You just need to go to Radio shack, and get a DC9V Adapter at 500mA and the correct polarity of (-) on the outside and (+) in the center. Original was a AHEAD AC Adapter Model ADB-0900500

Good Luck

TV will not power up


The original power supply is no longer available but you can get a replacment at Geeks.com part # 60w-12. You will have to change the plug that goes into the tv. The original plug has 2 wires. White(+) and Black(-). Be sure to observe polarity.

Power problem


probably "+" you need to check the polarity of the speakers, there should be something like this near where you plug in the power adapter: http://www.accesscomms.com.au/images/reference/powerplug-positive.jpg the above symbol would mean "+".
