    without knowing even who made it you wont get any info.
    you can use a meter to read the voltdrop of each colour - thats a good start.

      Ive absolutely no idea what the model or the brand is, thats why im confused. So i decided to open a thread here so that maybe others might have an idea. I found something very similar in mouser and it matches my specifications but its common cathode, not anode.

        7 segment LED displays: Common cathode vs. common anode
        by japlytic
        With 7 segment LED displays, are common cathode units more common than common anode units?
        From what I see, common cathode units have simpler drive circuitry.

        nacon ps4 wired controller faulty LED and trigger pot
        by jetuaime81
        I have a nacon controller which has some fancy RGB ring (4 RGB LEDs). 3 of 4 leds are not good and I am looking for a replacement. The size I measured is 3mm x 2.5mm and it seems a 3528 led would fit fine, and it's in common anode. But I am not sure what wattage it is. I have attached photos of led and driver ic (ak63rq1 I think).

        Also one of the triggers is malfunctioning sometimes, I don't know what these pots are called. I measured across the 1st and last legs (in circuit) seems to be 1.1kohm pot. I found some xbox controllers have this but they are 10k. Any info?...

        Operating frequency for motherboard common mode inductor/filter
        by J_T
        I have a question - I have replaced the PSU on my own iMac Pro. However, when removing the motherboard I knocked of a 120 OHM 30% 0.3A small surface mount common mode inductor/filter (~0602 size) in the ethernet circuit near the female RJ45 port.

        The closest match I can find on Mouser is 120 OHM common mode inductor at 100MHz - my question is this frequency correct for a motherboard? The schematic for the motherboard only provides '120 OHM 30% 0.3A' and the TDK part number does not return anything in google.

        Sorry, I am not experienced hence a basic question.

        CMOS battery drains quickly
        by magistertc
        This problem is based on my experience with an ASUS Z390 Prime motherboard, but it appears to affect other motherboards
        as well Install a new CMOS battery, configure computer, turn off computer and disconnect from AC power or switch off SMPS.
        Return somewhat later and find that battery is drained, dead, or weak. Clock is wrong, other settings lost, etc.

        Examine the power 'sharing' circuit -- when the ATX 3V supply is on, the computer will function normally. The computer is also
        configured to support the RTC and some volatile RAM (when SMPS is on). What you may...

        HP ProBook 450-G2 LA-B181P - What is a common resistance?
        by Jane
        I have faulty HP ProBook 450-G2 LA-B181P - doesnot start. When connecting a charger, the LED on plug in connector blinks from yellow to blue. (I tried to search a short on mainboard.)
        What is a common resistance ( to ground ) I should measure on a coil that leads to VGA chip(RT8880CGQW) ? I measure only about 9.6 Ohms. Is it normal?
