    B&K 1760 Tripple PS has one bad side

    Does anone have a Schematic? Tried to charge a battery and it screwed up one bank or side. The readout shows zero voltage and the constant current
    Par led stays lite up. The other adjustable and 5vdc are good.
    Schematic is greatly appreciated

      Opened unit and started checking simple things first. Found a shorted 1N5002 Diode.
      The bottom half is all rivited together. Not made to be serviuced. I was able to just reach it from the side. Put a 1n5008 and it works fine. Reassembled. Thanks Guys

              Magnum IA.100 Amplifier Switches on, No Output, Possible Input Side fault?
              by flibidy
              I have here a Magnum IA.100 which belongs to my parents.



              The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.


              Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.

              Lenovo E15 Nm-c421 usb-c work only in one side
              by bouny56
              ​Hello

              Laptop E15 I5 10gen
              Mb nm-c421

              I have a problem with the usb-c power dc.
              The motherboard start only in one side of the usb-c

              Replace the usb-c port 2 times same problem

              With the usb-c meter, one side 20v ok, other side the usb-c meter don't come on

              Try to test the pin with the Mechanic Tail insertion tester and every pin are ok ?

              Can the pd controler be the fault ? Or something else maybe ?

              Thx

              TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
              by howardc64
              All left and right refers to looking from rear of TV (or looking from front with TV upside down)
              • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
              • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

              A2442 MacBook Pro 14" Two Left SIDE USB C ports charge but no data
              by Stephen
              Right SIDE usb.c port charges and transfers data without issue, two left side uSB c ports charge but do not receive or see data. Was liquid damaged, and repaired significantly and thought we were in the clear but appears this is the last issue that is rearing its head. I am trying to locate the RETIMER chip that communicates the DATA TX/RX but I cannot seem to find it on the schematic or maybe I am just so tired my eyes wore out lol. Any help would be great.

              DELL Latitude 5520 - charging only on one side of usb-c
              by JarzabekPZ
              DELL Latitude 5520
              MB: South Peak 15 MB (DDR4)
              Charging only on one side of usb-c on both ports. I have replaced one of the ports but still the same. Checked for short, nothing is getting hot under thermovision. Usb meter is not coming on one side, on the other is coming on and showing 20V.
              Any sugesstions where to look for fault?
