I have no idea what this is. It has a screw thing on top. Any knowledge is appreciated.
It's the rounded blue part; the screw part is white and has “SO2” written on it.

\$\begingroup\$ Try focussing in on the object with more care. And, tell us what the component reference is printed on the PCB. \$\endgroup\$– Andy akaCommented Nov 5, 2022 at 12:20

\$\begingroup\$ Welcome! Can I ask what kind of device is it in? \$\endgroup\$– jonathanjoCommented Nov 5, 2022 at 12:22

\$\begingroup\$ @jonathanjo hi yes its from the PCB of a Eurolite TG-5 manualslib.com/manual/2254729/Eurolite-Tg-5.html#product-TG-5 \$\endgroup\$– lucas.ss.05Commented Nov 5, 2022 at 14:30

Looks like an out of focus broken trimmer pot.
Did it origionally look like this? The S02 is probably 502, a 5k ohm pot.

\$\begingroup\$ exactly! yes the PCB says 5K and its 502 i think yes. thanks a lot \$\endgroup\$ Commented Nov 5, 2022 at 14:30

\$\begingroup\$ question, whats broken about it? Im trying to fix this PCB, it might be this \$\endgroup\$ Commented Nov 5, 2022 at 14:35

\$\begingroup\$ @lucas.ss.05 In your photo it looks like the top part of it is missing. \$\endgroup\$– GodJihyoCommented Nov 5, 2022 at 14:38

\$\begingroup\$ I have it, just didnt take the picture. Is it possible to just solder on a 5K resistor there? \$\endgroup\$ Commented Nov 5, 2022 at 15:18

\$\begingroup\$ @lucas.ss.05 That top part isn't meant to be removable, so if it's not attached you'll need to replace the pot. No, you can't just put a 5 kΩ resistor there; a potentiometer is an adjustable resistor and in all likelihood this one was factory-adjusted to exactly the right value. The "5K" refers to the potentiometer's maximum value, and the value you'll measure between the two end terminals (the two that are on the same side, for this one). The third terminal is moved along the resistive track by the screw, so the resistance between that terminal and either end is adjustable. \$\endgroup\$– HearthCommented Nov 5, 2022 at 15:54
