    Viore LED42VF80 automatic turns itself off

    As soon as I power the tv on, it shows the Viore logo then it flicks off. The power light stays green.

      hey i know this thread is almost a year old. I know what's wrong with the tv 's if you look at the power supply where the panel plugs in, the one between 4 two wire plugs and the sound on the upper right. the one in the middle makes the led back panel brighter, if you unplug it you wont no more problem with it but it will be darker i have no bulged caps, if you plug it back in it will start to flicker again,then go out. so i know its either a bad cap but i can't figure out which one. Or the tranformer. I am a repair tech viore.

            Thanks, that site doesn't have Voire listed as even a manufacturer of T.V.'s.

              I tried unplugging that wire and the T.V. wouldn't turn on.

                That's part of my signature, and the reason Viore isn't listed on my site is because it is a re-badge name. The actual manufacturer will be some company in China, probably.

                  Re: Viore LED42VF80 automatic turns itself off

                  I bought the Power board and the main board, and still this TV turns off after awhile. It seems really weird because it will sometimes stay on for a good hour or two.. but eventually it goes off. I have moved it, just lifting it up and down a bit.. and it has gone off sooner.. Anyone have any idea's? They would be appreciated. -Namaste

                    I still have this LED 42 inch.. the Guy never came back to get it because I couldn't get it fixed. I bought both the video mainboard and the power board. The TV won't even turn on now. The light is on.. turns green even. But the back light never kicks on. Does anyone know where to see a service manual for this TV? LED42VF80

                      Re: Viore LED42VF80 automatic turns itself off

                      You are sure that those boards are OK which you have purchased?
                      I have just worked on a similar 32" one and I was ready to give up and I have just re-soldered the connector joints, transformers, I don't remember which IC but it was in the primary section, 16-20 pin IC?
                      To my surprise, the TV just turned on.
                      Did you try flexing the whole TV? I heard people doing this and the TV turns on.
                      This TV had image if I used a flashlight on the screen.
                      This TV, had the worst soldering that I have seen in my life. I think that were soldered on the boat by hand, while were shipped here.

                          This symptom sounds like a bad mainboard. But with this brand, could be a bad solder joint too.

                            Dead unit even with a new power supply, We have found that the problem is inside the LED panel, To be more specific the red B+ wire on the led strips is touching the aluminum ground plane on one or more LED strips, To verify without taking the panel apart just disconnect the 4 sockets and measure for a short across the pins, If shorted then the problem is inside the panel.
                            Reason of failure is the close manufacturing tolerances, The Plexiglas reflector is to big and the corners right on the top of the solder connections are pushing against the red B+ wire on the left and right strips thus creating a short.

                              The order of the four 2 wire pins in the upper left of the power board makes a difference for start up. If the first two are out of order it will not turn on the display.

                                    I have repaired this model tv in the past and it was bad solder joints around the transformer. I would start there. Hope this helps.

                                      MacBook Pro 14" M1 Pro Turns on functions then turns off when I plug in USB C cable to reset the computer. I disconnect the battery fully and then reconnect it and it won't turn back on. After letting it sit for a day I plug the battery back up, and the MagSafe 3 cable and it powers on and stays ons, once I plug in a USB C cable into the port closes to the MagSafe port it turns off and the Amber light turns off and won't turn on. No water damage, nothing, I want to do a DFU restore to wipe the computer since the customer stated they did an update and ever since it just decided to not work...

                                      LG L192WS-BN backlight turns off after 1 second
                                      by www
                                      I am testing an old LG L192WS-BN monitor I have that gives an image, but has a backlight issue. When you turn it on the backlight turns on 1 second and it turns off, turns on again, 1 second and it turns off and stays off. Using a flashlight I can see there's still an image.

                                      I replaced a bulged cap on the main board, but made no difference. I also got another exact same model monitor that has a broken ccfl (the connector got ripped from the panel and the main screen connector is also broken so I can't use this panel to test), tried using the main board from this one, same issue....

                                      Read more. When the power supply is connected, the front panel indicators light up briefly.
                                      When you press the power button, the button indicator lights up. The board works
                                      there is no image, there is no matrix initialization, there is no image on HDMI.
                                      When turned on, the fans do not spin, but when they warm up they start spinning.
                                      When you turn off the button, the fans spin up to full speed for a short...

                                      Samsung UE55F8000SZ Turns on and off immediately
                                      by Egidio85
                                      good morning, I have a samsung UE55F8000SZ tv that turns on, shows the logo and turns off after 1-2 seconds.
                                      This defect happens continuously, hearing the classic click of the relay every time.

                                      Power supply board BN44-00636B

                                      disconnecting the mains and lamps from the power board always causes the same problem.
                                      Is it normal that without anything connected this power supply turns on and off cyclically?
                                      any suggestions on what to check?

                                      thanks in advance

                                      I've had a friend discard a TH-65DX700Z Pansonic Viera Television and I've decided to have a go at repairing it. If possible could I please get some advice in terms of diagnosing the problem so I can purchase the appropriate parts for repair whether it be components, a repair kit or a replacement board. I am happy to post pictures if required.
