    I suspect a faulty LED backlight issue
    To check you will have to dismantle the LCD screen

      But disconnecting the led from the power supply it should be on with out the led connected. At least should be audio on the main board, with a flash light I try if there's something of video but theres none.....I think it might be main board problem..the power supply what I know is that if you have your standby voltage at 3.3v or 5v your power is good....and the problem is mainboard. Well that's what I know.....any opinions out there, am I right????

          The problem was the leds inside they were short-burn at the look they didn't seem like it,but what I did is to make a rail of 18 ligth led. Why I did this??? to test the power supply if it working good and for that reason to be sure was the led or not...in this set of tv it only has a one rail of led strip which consist of 18 led ligths. So what I did from other scrap sets I took the strips to add up to 18 leds. I used rails of leds of 4 leds on each and of 5led and try to make it fit. But basically that's your problem on this set..

            by pajdek
            Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok.

Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so 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....
