    Unrecognized component marked on the board as capacitor

    Hi All,
    I have 2 unknown (to me) components on the board - one designated as C1 the other as C160, suggesting that they are capacitors. See pictures. I have never seen capacitors like that. Both of them are shorted, none of them has any markings. The board comes from a commercial (heavy road planning equipment) GPS unit. If they are capacitors, they shouldn't be shorted, suggesting that they are faulty. Have no idea about their value. They both have something that appears as 2 blue bands. Any help will be enormously appreciated.

      They are feed-through emi filters they will check shorted from end to end, the capacitor is between the end and the center
      Maruwa CTH or TNH73 Series
      Best guess on part number TNH73R2A104S15A

              Thank you for your fast answer! Since I posted my question, I tested them further and discovered that indeed, they show as 2 capacitors with common ground in each package, both reading on the capacitor tester as 5 nF each end. I learned something new today .

                  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...

                  Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
                  Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                  Sony xbr-65x900c main board issues?
                  by jb_Bak
                  Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

                  Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
                  Power Board Connector that goes to Main board
                  CN6401
                  Pin 01 NC
                  Pin 02 NC
                  Pin 03 "BL_ON": 0V
                  Pin 04 "N/C"
                  Pin 05 "STBY 3.3V": 3.5V
                  Pin 06 "GND": N/C
                  Pin 07 "AC_OFF"...

                  Panasonic TC-P54VT25 No image. A or D board?
                  by canadaboy25
                  I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

                  The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

                  I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was...

                  Physically bending the T-Con board creates horizontal dotted lines on OLED55CXPUA
                  by fredtred
                  Hello!
                  I have been trying to solve this issue the past 12 months to no avail. I have been a lurker here during that time but finally decided to post my problem and see if anybody knows a solution.

                  Problem
                  My tv (OLED55CXPUA) has an issue where it displays horizonal lines of dotted artifacts.

                  (See Attachment 1)

                  Self Diagnosing
                  After a very long troubleshooting period I traced the issue to the T-Con board. If I gently flexed/bend the board I could make the display go from GOOD to BAD and vice versa. I have ruled out the connectors/wires...
