How to Identify Unknown Resistor Value With Only One Black Band Visible on 12V 10A PSU?

I'm attempting to repair a 12V 10A switching power supply. Although I have bought a new replacement but i think it's good to have such beefy supply handy.

During the initial stage of repair the board was having fuse and switching mosfet blown out, have replaced that.

But when connected to mains there's clicking (ticking) noise coming from the transformer. Then i googled it and found similar problems people having. According to those references i replaced all electrolytic capacitors and problem still persist.

I read on another forum that, this is because the board is getting its over current triggered and that is causing ticking. There it was advised to check for short on load side and then check shorted components on board. I found a resistor thats shorted and unfortunately the color code of that resistor is rubbed off and it's 8th of a watt resistor.

So how to find the unknown value of a resistor. Only black band is visible. And its the second band.

Datasheet for the ic is attached and the resistor is connected to pin1 and it is in series with 10nf cap which goes to ground.

Hi James-there is some chance that the resistor is not bad- it may just be a very low value.  Those resistors rarely fail to a short.  Instead they usually open.The ticking sound you mention may be something referred to as "hiccup start", where the power supply will continuously try to restart if it is heavily overloaded. Have you measured the resistance across the output leads with the power turned off?  You said you replaced the MOSFET.  If it was isolated from the heatsink, check to make sure the replacement is isolated.Is the new power supply identical?  Comparing things between them may be helpful.By the way- the datasheet is not attached to your original post.

James, I am wondering if this is maybe a zero-ohm resistor:- they only have one black band- as Rick says, resistors almost never fail to a short, they go open.- you don't say specifically, but sounds like it was not burned out?I wrote an article on resistors some time ago and mentioned these components:https://www.eetimes.com/author.asp?doc_id=1324089&page_number=4
If you post the datasheet we could see if there is supposed to be a zero ohm connection from that pin to somewhere....  oh and a photo would help!One other thing...if the replacement supply is of the same type, you can compare the boards and values.Cheers // David
