    Thank you for confirming this. I was searching online for a replacement board, but was not able to find any... so I think my options are either baking it or trying a mail in board repair service. Has anyone used one of these services or know a trusted one?

        One there, 72 bucks seems a little high to me? BUT they don't seem to be readily available so might be the best bet:https://www.tvpartstoday.com/EBT6139...bt61399411.htm

            Does not seem to be quite exact the one I have:

            EAX63969204(0) vs EAX63969205(0)
            EBR73358205 vs EBR74235304

                Guess that's a good question, I matched it up by part number LG EBT61399411.

                    What is your full panel number? it's on the metal chassis someplace.

                        Not sure which one is the correct number... but here is everything:

                                How did you figure out if it was a match or not? Just in case others show up I'll know how to check if they can be compatible even if having different numbers...

                                    Key is to match your service code on the back cover of the tv, it is 47LW6500-UA.AUSYLUR correct?

                                        Yes, the service code on the back cover is 47LW6500-UA.AUSYLUR as well as on a sticker on the main board that includes the different number EBR74235304.

                                            Yes, certain numbers can be different, usually your good to go when you match the service code.

                                                    Thank you all! Ordered it, hopefully it will work. Will keep you posted.

                                                        Hi Folks

                                                        I have an MSI PRO Z690-A DDR4 (MS-7525) which underwent LGA1700 replacement and had a missing resistor in the VRM section. The missing resistor RV170 (49,9Ω) has been resoldered, and I have also replaced a demaged LGA1700 socket.

                                                        Generally the board does boot to Windows, but not always in the first attempt, but after the second attemp to boot the board with Power Button. Also restarting the board from Windows ends up with stuck boot process, but restarting the board again (long push Power Button or switching off and on PSU). Under Windows etherything works                                                        ...

                                                        by Alain Renteria
                                                        Got it for free on marketplace because it stopped working after a storm.

                                                        When I began troubleshooting the power supply, I fried 2 fuses and a mosfet by shorting 2 pins on accident, but I've replaced those components.

                                                        The tv had a soundbar connected, which was also killed by the storm. On the tv side I found a transistor shorted on the hdmi 2 (arc) and a lot of capacitors shorted on the main board.

                                                        Disconnecting and reconnecting the psu to main board cable, while still being connected to 120 V AC, would wake things up, such as a red light from the optical...

                                                        Hi everyone!

                                                        First post on here so do tell me if i'm doing anything wrong. I have a laptop that came in with a broken hinge, but a healthy LCD. We replaced the LCD rear cover and now we do not get an image on the LCD anymore, though we get one via HDMI. There is sadly no schematic or boardview available for this motherboard (Bucks U42 DIS 17817-1) as far as i can tell, but I was able to identify which of the important pins on the LCD eDP connector (30 pin 2 lane) correspond to which pins on the motherboard display connector (which is 40pin, 30 for LCD and 10 for camera/face rec etc)...

                                                        I have a Vizio D32f-E1 LCD TV that does NOT have a TCON board.

                                                        This TV recently went through some 'death throes' and now won't boot. The first problem that began to manifest was while watching tv, the screen would 'freeze', and the image would dim over a few seconds until it was very dark. HOWEVER, the audio of the show would continue as normal. I could power off the TV for 5-20 seconds, power back on, and the video would be normal. This would occur 1-3 times when the TV was first started, and would not happen again after the TV was 'warmed up'. Not ideal, but this glitch was manageable....
