Led Christmas ornament not working.

Hi, I was wondering if someone could help me. I bought an led Christmas ornament the same as the one in my attachment and it didn't come with an adapter, so foolishly I used a 12v one to try it. All the lights came on and the water fountain worked, but the lights were dim and the water stream far too powerful. I then bought the right adapter which was rated 4.5v and although the water fountain still works, only one led bulb comes on. If I plug in the 12v all the lights work but dimly, so they have not blown. Could anyone tell me what I may have done and is it fixable?

Thank you, Kev

Not without more information.

Does it have a model number? Is the power jack labeled?
Hi Dennis. Thank you for your quick reply. It does not have a model number, but I have attached a picture of the box and the adapter info. It seems that if I plug in the 12v adapter, the led lights come on but dimly. When I use the proper 4.5 volt one, only one led comes on.

Kind regards, Kev

A blob chip looks like the black blob on the board below. It is an IC hidden under some encapsulating compound.
They are not replaceable.
