    LF501EM6F Emerson 50" tv

    I have an LF501EM6F Emerson 50" tv with a main board model number BA4GU5G0201 4. I found two shorted caps on the back of the main board. C3825 and C3828.
    I am wondering if anyone has a board they can measure these caps on and let me know what they are? It might help someone else with one of these chirpers too. I measured 5.6uf on one I removed but it would be nice to have a little verification.

      If you measured a shorted cap, then you wound't read anything good in value. C3824 and C3827 are parallel to the ones you took out. So measure these.

          Look like they are in parallel. If so they are probably same as other two
          I assume no responsibility for any stupid suggestions I might post.

              What is the resistance reading between the two pads on the board where the caps?
              It will not be showing 5.6uF if you have shorted cap, you can easily verify that by shorting you cap tester leads together to simulate shorted cap measurement.

                  No I pulled one of the others and then replaced it so it would not run away.

                      I traced the line pulling and replacing components in the circuit until found the ones that were shorted to ground.

                          So did you find the problem and which component was it?

                              I replaced C3825 and C3828 with 5uf caps. Tv is functional. You're mileage may vary.

                                  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.

                                  LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
                                  by Hakuu
                                  Hi There,

                                  This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

                                  After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

                                  More Details

                                  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:

                                  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...
