Hi, can anyone help me with identyfication this two tiny objects that are marked in purple circles on this photo:

There is AHF inscryption on them.

I ask becouse one of them burned out and i hope that exchange for new one will help.

Sorry for my english, i hope you understand what i mean.
 

Each is 8 pin. The labels are not at a high enough resolution to read.

If you will post a close-up photo, someone here might be able to identify the IC's.

If your camera does not focus at that short a distance, then it will work for you to shoot through a magnifying glass. It may require several tries to get a sharp image.
 

Hi,

A friend who has a dragon had a look , he said -

Only markings I can see on the chips are a faint "AHP". No idea what they could be.

He has never seen a circuit diagram for the dragon board.

If 2 chips are physically blown its likely other parts may be damaged... might be easier to get a new board or a cheaper isp usb programmer.

Could try searching the web to see if its a common problem or if anyone offers a repair service, long-shot though....
