                No Power!! I thought having a power supply and lights did not fit that description
                Do we not even get to look at the main board - I am sure at least one member had problems with those unusual connectors between all the green boards and the power supply. Wasnt with the same set and I cant find it now - it was months ago

                    From my post #3, I know it was the main board is the problem due to many missing signals, and the OP wants to find out how to test the power supply board which is now confirmed that it is bad main board as I suspected.

                                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...

                                Driving a Sharp TCON/panel with a universal main board
                                by advant
                                This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.

                                I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...

                                All left and right refers to looking from rear of TV (or looking from front with TV upside down)
                                • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
                                • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

                                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 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
