    Need schematic diagram of this Super-MITE 11, SM11-2/230A

    Anybody know where I can get a schematic diagram of this power supply? It is rated 12VDC@84A switching power supply. The unit is not working and have some dark marks on the pcb, a sign of overheating in that area.

    Thank you in advance.

      Can you upload some high resolution pictures of the board(s)?

          Attached photos as requested. Although may not be a high resolution but that's the best I can get.

              It is a LH Research power supply, Super-MITE 11, SM11-2/230A

              All I could find is manual and schematic for SM10 https://archive.org/details/bitsaver...lJul79_2048801 which might be similar.

              Unitrode NTC3023 IC DIP-24 I've never seen before

                      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                      by Tynan Dill
                      I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                      Upon bringing it home and plugging it up, it showed a standby light.

                      I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                      The screen seems to blackout and stay black, but with a flashlight I can see the display.

                      With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                      Assuming...

                      Arcam FMJ A29 Stero Amp - schematic diagram of power supply
                      by birchy7
                      Hi, I'm hoping someone on here can supply or point me in the right direction for a service sheet for the above amp.
                      Its on the bench, no power, all 3 fuses on main board are intact. no voltages are coming out of the mains tranformer, but it is recieving its input voltages ok, theres a relay in circuit with the transformer that might be my problem, either that or the transformer itself, would love to have the circuit diagram just to see how exactly this operates, many thanks in advance...cheers

                      EDIT, sorry made a typo, its the ARCAM FMJ-A29 i need, not A32, sorry all

                      Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
                      by sam_sam_sam
                      I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

                      One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

                      I need schematic and diagram for Asus X556U Rev2.0 mb
                      by Kirve
                      "Hello friends. My Asus X556U laptop is not charging, not turning on, etc. I wanted to repair the motherboard, partly for learning purposes. One of the capacitors is giving a 24V output, and one of the MOSFET pins is also giving a 24V output, and honestly, this surprises me. I think I need to replace the capacitor, but I don’t know the capacitance value. I tried searching for a motherboard schematic but couldn’t find anything. Can you help me find the schematic or diagram?"
