    Have to turn C1 on and off multiple times for it to fully come on

    Have to run LG C1 on multiple times for it to fully work

    If I have it off for a while I have to turn the TV on and off and handful of times for it actually display what it's suppose. The times it doesn't nothing comes up like the input or dobly vision logo. Once it's on I can turn it off and back on fine and the picture looks perfect.

    Unhooked everything except antenna. Reset tv to factory settings. Let it sit and when I tried 2hrs later turned TV on and sound comes through but no picture....

    LG UH652T doesn't turn on and stands is blinking once a second
    by mar1in
    Hi everyone,

    I've got this LG TV here that wouldn't turn on and be stuck in a standby loop (blinking red once every other second).
    Did test the following:

    * LED's seem fine as they all light up using LED Tester
    * Power Supply supplied around 111V for each LED Strips (2x edge lid strips)
    * PWR_ON would be at around 3V but dropping every other second (just like the standby light)
    * DRV_ON is doing the same
    * power supply has a green LED onboard, but that doesn't seem to do anything (stays off the whole time).

    Samsung NP750QFG-KA3DE does not turn on , Blue LED flashes 3 times
    by Egidio85
    Hi everyone, I have a Samsung NP750QFG-KA3DE , MainBoard VESTA3-15 BA92-24515A

    the battery is charged. pressing the power button the blue LED flashes 3 times and then stays blue. then the sequence repeats.
    the fan does not start.

    I noticed that I have no power on the processor and it does not heat up. could it depend on the bios?​

    any advice on what to check?
