    Re: ELEFW605 finding an EEPROM

    I noticed on the frc board theres a 6 prong socket. And the cable for thr backlight fits perfectly to it.
    Look at the back of the frc board, you will see that plug is likely for programing or testing the frc board
    UART_TX, UART_RX, ETC.

      I found a UART_TX and UART_RX but they're on the same socket as the bl plug that fit perfectly.

      This board looks like it doesnt get any power if the main isnt plugged up. so how would i test it.

        I have no idea what you are trying to do.

          I'm trying to get the backlights on. This tv has been moved several times sents it went out, i plan on buying a kit with all the boards. but i wanted to double check the screen is still okay. It looks okay to me upon glancing at it but you never know right? I dont wanna mess with it if its a bad LED or something. I had a hard enough time taking the panel off a 42'. I dont even want to think about trying to get a 60' apart ><

            Could try this one, free shipping if you use ebay, they don't allow returns on these: https://www.ebay.com/itm/Element-ELE...wAAOSw3utY7RJy

              Disconnect the cable's Con3 and Con6 from the main board, plug in the power supply an check the voltages on con3 and con6 and mark them on the picture, that way we can tell the state of the power supply in standby, without the main connected. then we can tell if a pin needs to be taken high or low to change its state.
              You should only have the standby voltage in this state.

                    Yep thats the one im gonna buy. Soon as i know for sure the screen is fine i'll be ordering it.

                    I actually sent an email to them about not having my eeprom and they said their 'investigating the issue" So we'll see what they get back with.

                      Re: ELEFW605 finding an EEPROM

                      The first picture must be with the plugs connected. If you don't disconnect the main board you could damage it when forcing on the power supply. Also having the main connected could be preventing the blon and adj from changing state.
                      You need 3 resistors 1k~5k its not that important.
                      Connect the first resistor between stby 5 volts and PSON, that will turn on the power supply
                      Then connect another resistor between stby 5 volts and BLON and see if you get backlights, if not also connect a resistor between stby 5 volts and adjust pin

                          Sad end to this story. Your advice worked. it just needed a signal to BL ADJ to turn on. Sadly it appears the screen is cracked. My mom had taken it from her house to a tv repair guy then to my house and it must have hit a bump sometime then. Shes not great at being gentle which is why i wanted to verify the screen was ok before buying them. luckily i didnt order those parts yet. Thanks for all your help guys. This ones closed

                            Bummer, well at least you know how to test the next one.

                              Definitely learned how to do that. So it wasnt a total waste. Just wish i had done this first before wasting a week trying to figure out why it wouldnt turn on.

                              Aw well. You live and learn :/

                                Never liked the picture quality in those emersons, I'd look for a sony or panny maybe even an lg or sharp to fix up.

                                  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.

                                  Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

                                  Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:

                                  Panasonic TC-P54VT25 No image. A or D board?
                                  by canadaboy25
                                  I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

                                  The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

                                  I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not.

                                  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
