    LG 42LN5300 doesnt turn on periodically

    Hello. I have a LG 42LN5300. It will work for days perfectly and then all of a sudden it will not turn on. This also includes no RED Led standby light.

    Has anyone else encountered this problem with this model?

    Thanks in advance...

    I don't know if this will help or not. But I had a Sanyo TV that did this for months until finally one day the picture was just all distorted then it stopped working at all. It turned out to be the main board.

      No, but if you upload good clear pictures of the whole back side of the TV that will be a good start. Do you have meter to check resistance and Voltages?

        I've got one of these on the bench right now. Check the solder joints in the PSU where the power cord plugs in. At first I thought I had a no standby issue due to no LED on the front but I wiggled the cord and it came on.

          MSI GF63 THIN 11UCX (MS-16R6) LAPTOP WON'T TURN ON AFTER RESTARTING
          by RdeveLabs
          To all the members here...

          Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.

          So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But...

          Acer Aspire 4520 won't turn on after reboot
          by robante15
          Hello, I have an Acer Aspire 4520 from a couple of decades ago and I want to repair it solely for nostalgia.

          It happens that when I turn it on after having been disconnected for a long time, it turns on without problems, it tells me that the BIOS has been reset and that it will load the factory settings, if I tell it to continue, the computer turns on and everything works fine.

          The moment I turn it off and want to turn it back on a second time, or restart it and try to start it again, it no longer gives an image, and it no longer responds.

          If I remove the...

          Dell latitude e7470 not turn on .power buton on off and Run Power problem
          by masoksian
          Hi everyone,

          I am dealing with the problem of turning on and off my Dell e7470 notebook.

          The battery charge light is solid white, I press the button, the power indicator and the light on the button are solid for 1-2 seconds and immediately turn off.

          The system does not turn on, there is no post.

          I removed the RAMs and changed them, changed the battery, RTC battery, AC adapter, removed them and waited, tried again, it does not turn on.
          The problem continues in the same way.
          I tried to turn on the Fn key, nothing came to the screen....
