"trying" will be a bit of a challenge unless you can solder a lot better than the soldering in the pictures of soldered jumpers shown earlier in this thread. To experiment safely you could use a 1K ohm small resistor, either 1/4 watt or 1/8 watt, for the connection between the two points. The benefit being that if it is a logic path it will not matter and if it is a power trace then there will not be enough current to do damage.Shuriken proposed this bridge ... will it work?View attachment 258166
Hopefully, these will help finding the way to do it as I am in the same boat
That's some kind of glue/loctite to prevent voltage regulation. I don't know if it from factory like that or the company I bought it from put it there. I was able to scrape it off the potentiometer and now it turns freely to adjust the voltageWhat is that blue stripe is an attempted modification?
Fingers crossed! Post a pic of your work if it works, pleaseunderstood...
I try the proposed link let's see what happens ...

I tried inserting a 1k resistor, it doesn't change anything !!!
If that's the case, disabling OVP could be done by desoldering a leg on the IC. But which one?OK, so guess #1 did not work out as well as I hoped. It was a guess, not a declaration.
I also see two white connectors along the top edge of the board, one marked "CN702", can't see the tag on the other one. Those might be for programming the supply, as it looks like it has at least one processor IC. If it is digitally programmed then it is another game altogether.
