It is a shame that the identifiers on the chip are so out of focus.

 

You can't buy them from HP.

 

I usually source  my replacement chips from eBay or a hobby electronics website.

They could be MosFets, buck converters or a number of other chips.

 

Without being able to see all of the identifying information on the chip, few people could  precisely identify the chips or provide a source for them.

 

I suggest using a magnifying glass or microscope to see the chip information. Once you have it, post it here in a reply.



I am a volunteer forum member. If my suggestion helped you solve your issue, help others by marking that post as the accepted solution. Say thanks by clicking on the Yes button next to the "was this reply helpful?"
