Bush WI-1810 Internet Radio

[Johnny.p]

I recently bought an internet radio Bush WI-1810, it came with a power supply that when plugged in promptly damaged the radio. I discovered too late that the radio was 6v and the supplied adaptor was 12v. The radio still powers on but the wifi is not working. I have attached a few pictures- Image 2 showing the board with damaged component top right labelled U8. There are several other similar components like U9 (image 3) that I'm wondering could be a replacement.
U9 has a code on it S5EJI- I have searched several smd code sites and the nearest I can find is for a mark of S5E -listing shows (sorted for size) Linear voltage regulator IC LDO 1.5v 150ma.
I'm not too familiar with these components or if a nearly match will do. Any help appreciated. Thanks.

those chips are totally different.

find out where the 3 pins go.
it looks like the center is ground.
the left pin may be the input voltage.
trace where the right goes to work out the voltage.

and look left to Q1 - is it cratered?

i found a couple of pictures online - the regulators are the same - it just didnt look like it because you didnt clean the mess off the tracks

Thank you for taking time to look- I'll clean it next time.

Finally, did you find out what was S5EJI for? I got an Internet radio with the same problem. This IC heats up very much. It is wrong...
