Fried this component,where to find replacement for Acer-G226HQL

[90Ninety]

I accidentally plugged in a POE PSU (48V) into a monitor (12V) Acer-G226HQL

What appears to be a regulator , popped and fried with characters ( I think) :AME8815 AEDS330 T330 ?

I cannot find this exact component and just wondered if there was a similar one for sale I could use to replace it ?

I have a feeling the diode on the left also needs replacing , looks like 540 on that . I am thinking the monitor is salvageable

I did initially try to find a replacement board , there were some archived but none currently for sale ( https://www.ebay.com/itm/Acer-G226HQ...p2047675.l2557)

Re: Fried this component , where to find replacement

that;s a nice hole in the 8pin chip on the left.
is that regulator shorted by any chance??

Re: Fried this component , where to find replacement

here is the pdf, I think the diode is a mbrs540t3g On the board you linked the diode is an "S54"

There's no blown ( with hole in ) 8 pin chip , unless I am mistaken?

The regulator has a hole in it , Its pretty irrelevant if shorted or not don't you think? Its pretty much fubar

Finding a replacement is the challenge here

Do you know where I can find a suitable replacement ?

The PDF shows many variants; I feel lost figuring which is needed

Re: Fried this component , where to find replacement

I think I am beginning to understand
AME8815 is the family of regulators
AEDS means :
A Pin config
E Operating Temp ( 40 -85 )
D Package 263
S Number of pins ( 2 )
The 330 in the part number is the output voltage 3.3 V

Based on that information , I ordered this (below)

oh come on, it looks like a bomb hit it!!

Yeah I was staring at it a bit and it looks like it got a crater in it too:

It sure looks like big hole on that 8-pin device U1 to me too. 48V into 12V will sure cause lots of damages.

That crater is big enough to eat cereal out of..

also, up and right of it.
3x 75ohm resistors - center one may be toast!
strange as i suspect they are load resistors for the RGB input to provide impedence matching.

You call that a crater? This is what I call a crater!
