Is there anything that I could do to fix it myself

if you can read the schematic and replace smd parts, then sure, no problem. if not you'll have to determine exactly what is the problem first. i.e. is it U2 not generating 3.3v or is it some of the devices using 3.3v that have failed and are shorting out the 3.3v rail?
a good start is to measure the voltages I asked for as it'll go a long way towards answering oart of that and directing the next step.
on the other hand of you're not confident you can fix it, its probably better to wait for the replacement.
