Powerdrop_in TMS320DM6437 ????

Hi,

I am using TMS320DM6437EVM (DaVinci Processor ) for my small project.

I purchased all related components with this board(USB Conn.,5V MODEL SW108 Power supply etc..) from TI.

The problem  am Experiencing is that I  checked the voltage output at the adaptor pin which is 5v but after connecting this adaptor,  I am getting the votage of 1.8 v which means that there is some votage drop(may be because of some short ckt.) .I can't check the shortckt locations because of the kit fabrication.

I am completely stuckeed in this problem.

How i can avoid or overcome this voltage drop related issue....?

Please let me know....

    what is exactly loading effect related to the kit...?

    As I connected multimeter and checked it was showing 1.7v ..

    So shall i replace the kit or any other way to overcome this problem......?

    Definitely it will take more time to get the newer kit .so there is any other solution rather than exchanging the kit...........

    ( I just connected power adapter (5v) and i didn't connect the other components....As the indicator led is blinking with very low intensity ,so i checked this voltage across the power connector pin on board but it was showing 1.7 v only .... I  DID NOT CONNECT OTHER CONNECTION EXCEPT THE POWER ADAPTER......)

    Please tell me the way to handle the problem....
