Help identifying fried components

[Spray110]

Hi there!

I have a pcb for an HP 2311xx series monitor with fried components, do any of you electricians know what I could use to replace these with?

The pcb model is 492A00191200H, and unfortunately I cannot find a clear enough picture to identify them.

Thanks!

Here's some better pictures. Zoom in and you can make out the chip labeling.

Thanks! The smaller one is still quite hard to make out, but I'll try! Also, any idea of how to search for these? I don't know how to type the information in. The bigger one seems to be AX5630-33 1021A but nothing really shows up when I search for it.

*edit*
Rather, is there a way to see what values they have?

That's because it's an AX6630, 3.3V LDO.

The other one appears to be RT8253AH.

Thank you so much for the help!

One more question, is the model name important, or is it about the values? so as long as the values are correct, the replacement doesn't have to have the same exact writing on it?

Also, I just noticed I need to replace yet another fried component. It's got the exact shape and size as the AX6630 one, the writing says NIKOS P8008BD QNC6N0203 and I can only seem to find replacements from sites like aliexpress. Is there a way to read the values of it based on the writing? I cannot seem to find some information about this particular model.

What do you mean exactly? The replacement is pretty much guaranteed to not have "the same exact writing on it", because part of the marking is the datecode. However the part number should be the same otherwise, although for more "generic" components you can substitute one with equivalent specifications. I'll let others here elaborate on the finer points of that.

Thanks! I guess I'm just kind of lost searching for replacements. I've been searching for parts with the same values over at Mouser, but I cannot seem to find fitting replacements, the values just doesn't match up. Is it normal, having to search far and wide before finding such simple parts or am I just an obvious newbie?
