help fixing netgear switching adapter

[pharaon]

the electricity went off suddenly and since then the router keep rebooting

the output volt now is : 13:90
current 5.2
i think it should be 1 A
any one have an idea how to fix

If you measured the current directly across the power supply then you were:

a) doing it wrong
b) risking damage to both your meter and the power supply.

Try finding another 12V 1A adapter and see if the router works with that.

i did and it work just fine although its 12v but 0.5 A

You can continue to use the 12V 0.5A PSU and your router will probably work just fine. If you really want to repair the original PSU, I suggest you start by measuring the blue 1000µF capacitor which corresponds to the burn marks on the other side of the PCB and R18. Does your multimeter measure capacitance?

This is a classic case of
"don't fix it, it ain't worth the time or money" .
Just get a new one ,it is dirt cheap,here

R18 = 1.7 K
