    Re: LED TV doesn't want to turn on

    I have found a can of duster for about 5 EUR, so I will try with that. I just need a short tutorial on how to do it, since I never done this before.
    TV should be plugged out? From what I read in some of the first posts, I should spray it with a can upside down? For how many seconds I should spray? And lastly, should I keep spraying when I plug in TV (so it doesn't get warm), or it should be enough to just spray it before plugging in?

    Thanks.

            Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
            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 55EC930V OLED - swich on swich of no screen
            by maxim2511
            My Oled Tv is 55inch tv, 3 days ago I notice that middle of the screen is getting warmer and on picture I have ghosting, missing red color. Color red was still displaying, but it was not so strong as corners of the screen and watching some movies makes me angry.
            Then I get an idea to take it apart and clean boards from dust.
            In side of Tv was not so bad, I take compressed air in can, and gently blow up.

            Also I was thinking to styrofoam sponge to isolate power board from screen that the middle of the screen will not worm so much. Because Led on screen when gets higher...

            by m1ch43lzm
            Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
            Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

            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

            TV Model - LG OLED77G1PUA

            Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...

            Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
            by sam_sam_sam
            I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

            This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

            After all of...
