    NEQ2 on SMD Transistor

    I'm new to SMD devices. I have recapped several boards with 100% success, but I'm new to the world of SMD.

    I was given, meaning I kept it from the trash can, a nice SONY SDM-HS75P 17" flat computer monitor.
    It looks like it would have been a top of the line model. It has 1 bad SMD transistor that is leaking and swollen.

    It has NEQ2 on the top.

    What can you tell me about it?

    Thanks

      I believe that's a reset ic ASM809SEVRF-T This mfgr uses different markings

        I finally found the schematic for the Sony monitor and ID'd the device. I found 4 online and they should be here after Christmas. I'll try to post part of the schematic ID.

          The 4 resets finally arrived in January from Taiwan. the only place I could find the exact chip.
          I replaced the swollen reset but the problem still exist. Following the trouble shooting guide from the factory, the reset is bad or if good, check the Crystal, if that's good replace the main control chip.
          I cannot change the main board chip, it's too big.
          But today the matching crystals arrived in the mail. After I replace the crystal and the problem still exist I done.
          I'll save the boards as spare parts.
          I'll post the results in a few days.

            Behringer Eurolive B205D repair - help identifying transistor
            by magneh
            Hello
            Got this speaker from a friend , defective. Power led comes on and off , in a loop.
            Disassembled, got the board out, and after a bit of measuring I found a low resistance on a 5v6 line. With a bit of current I found a transistor heating up on that line (labeled T1 and 113 as on pic).
            After removing this guy, I got a value of 0.7 in diode mode on that 5v6 line, which before had 0.02 or something like that.

            I tested powering it up without the IC, and the speaker turns on and stays on, and works fine

            Still, I need to replace this transistor....

            help to identify transistor msi ms-15ck1
            by elsomer
            hi people, i need some help to identify a transistor(q14) that is missing on the board, so the gpu has no voltage i think that q14 activate the phases for gpu, but i dont have schematic or boardview, but i think its the same transistor than q15 and q16, thanks...

            Help with blowing transistor NAD T752 receiver
            by rddube
            Hello everyone,

            I guess I need help from the masters to try and find what is frying a 2SC5669 transistor on the left channel of this front center Amp for a NAD T752.

            Was working perfectly and all of a sudden I heard a pop, and then a glow from the amp. Not only did the 2SC5669 burn a leg, but R520 which is a 220 ohm resistor partially burned - it now measures 110 ohms.

            I bought this amp second hand fairly cheap as it was not working, it went into protection mode. I finally traced it down to the same transistor Q510, the one that just popped. It was shorted...

            by amigo744
            hello there,

            xbox series x hdmi u82 transistor 5 pin,

            can anybody tell me voltages of this transistor in standby and power on mode ???

            on which pin of this transistor are the voltages ?

            regards
