Yamaha PSR 520 won't power up past a second, even with new batteries

I've installed new batteries and all of the sudden, it won't power on...it comes on for a brief moment, and then the LCD display goes black and the instrument quits? HELP!

Broken power connectors on PSR Keyboards
by: Yamaha Keyboardist

Hi all...

A common problem for 'pre-PSR1000/2000' series like my own PSR-740 - is the 12 volt power jack on the back panel...
What holds it in place is JUST THE SOLDER JOINT!...Generally, if you melt the solder (add a bit if necessary, but NOT ACID CORE...ONLY use 'electrical solder')...you can restore the power connector to operation.
But the mounting for all the jacks is the same...What I did was surround the square 'jack housing' with some clear silicone...basically, 'gluing' the connector assembly to the circuit board...BUT, make sure you fix any problems with the solder joints FIRST!!
good luck!

i found out that it was a bad solder joint on my board. i reheated the soldier where the plug for the power cord on the board is and it works just fine. just thought i should update this for anyone having the same issue.
