    VW42L FHDTV10A intermittenly works

    Hello.

    I inherited a Vizio VW42L FHDTV10A. 8 out of 10 times it will turn on and work perfectly. The other times, the amber light will turn to white, but no video or sound or backlight. Nothing. I read through all the threads and did not find any posts with this particular issue. I was wondering if anyone else has encountered this intermittent issue. It is probably on its way to permamently failing so I am hoping I can fix prior to that.

    Any advice/suggestions would be very much appreciated.
    Thanks..Joe

      Post good clear pictures of your board, especially around the connectors so we can see the labels, then we can give you the test point test.
      Also read about how to test the voltage regulators which there will be many of them on the main board.

          Dell ATX PSU won’t start, but forcing it works fine?
          by CapLeaker
          Got a case of something new weird at work. There is an old 2nd gen Intel i3 in an old “Pizza box” shell that has a small form factor power supply. Unfortunately I forgot to take pictures and model number off it.

          Anyway, I get to work and get to look at this computer. Standby LED on the PSU is on, but the computer won't start. Hmm o.k. take the battery out of the main board try again, nothing. O.k. then… unplug the power supply from the main board and put in a full size ATX PSU (yeeeesss! Exact that blown Powerman IP that I fixed a while back), plug it in and the old...

          MacBook Air A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)
          by rounin
          Hi everyone,

          I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

          🛠 Original Issue
          The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
          Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

          I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

          ⚠️ New Problem: One USB-C Port Only Works in One Orientation...

          Kenwood SW-505D no sound issue and pops from time to time when it works
          by ex250
          Hello mates,

          I bought this subwoofer a few days ago used and blind and it works erratically, as far as I could see, it has been tampered with, the speaker is not the original one and of 8 Ohm when it should be of 4, and there are some welds like reworked by the boards.

          It doesn't have much power (expected more from it) and it distorts if you increase the volume over the middle, maybe it's because of the high impedance of the speaker. The problem is that it has sound when it wants, the led panels all work correctly, you can hear the power relay on power on, but right now...

          a2141 820-01700 internal display not working / external works
          by eurowill
          Hey ya'll this is my first post on here. I recently aquired a used/broken 2019 mbp 16 a2141 with the 820-01700 board. Seller told me that the laptop needed a new lcd. However upon doing some troubleshooting i found out the lcd is fine.

          Laptop boots like a normal, plays chime, touchbar lights up however there is no image on the internal lcd. If i connect and external monitor while its already on, nothing happens and no image is displayed on external. However if i restart or boot the machine while its plugged in, the external then works and a backlight is now visible on the laptop....

          EIZO CX270 - No signal but Backlight and Panel works, logo works, admin menu works. OSD doesn't. What?!
          by vf fa
          Hi, so i guess I´ll have to make a new topic here, as i browsed through hundreds of other threads but couldn't find a solution to my problem yet.

          I got a EIZO CX270 from a friend. He said it doesn't work anymore and wont display any signal or take any OSD inputs. Well, as an aspiring photographer I couldn't say no, could I? Thought it was an easy game, replace a bad cap and have a working monitor. But nooope, it wasn't supposed to be this easy.

          So let me start with the problem description. I'll try my best not to skip anything so this might get rather long.
