    Insignia NS-50DR620NA18 Diagnosing

    Hello everyone. I am trying to diagnose the issue with my Insignia TV. Out of the blue one day the TV started showing colored vertical lines on both sides of the panel. I have taken the back off and removed the ribbon cables one at a tome from the TCON board trying to diagnose which component is bad here. With each side plugged in independently the issue remains on that side and the other side is all black. Is this an issue with my main board? Bad LCD panel? I really don't wanna buy a main board only to find out my panel is bad. Pictures attached.

    Thanks in advance for all the help and suggestions - this forum seems like a great community for issues like this.

      Look hard at the tab bonds on the LCD. My guess is someone washed the TV and the liquid ran down.

          I actually see no liquid damage on any of the tab bonds.

          I got my meter out this afternoon and started probing around. Found about 10 caps shorted on the TCON board. Even with the led driver ribbon cables unplugged. I ordered a TCON. For $15 new it's worth a shot!

                  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.


                  What Ive done........

                  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?
