            In this thread the pictures are of the inverter board and the part is referenced as the power supply/inverter board. The eBay link is for the power supply board. Is the issue caused by the Inverter board (part number BA8AF0F01032) or the power supply board (Part number BA8AF0F01023-1). I have no burn marks on either board, but have the issue with the green light flashing when power is selected "ON", display flashes and then the TV shuts down and the red standby light is on. I can hear a slight buzz noise coming from the Inverter board when powering on.

                I have the same Model....the very slight buzz is usually a shorted zener diode
                or very possibly, more than one shorted! I replaced D644 43v 1watt on the power board, but now need some help identifying D635 zener diode. Marking looks like 20B, but not sure. It is glass, 1/2 watt..... Can anyone help ?

                        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.

                        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...

                        Philips 65PUS8518/12 distorted image after main board replacement
                        by tuner2000i
                        hello everyone,

                        I don't normally do tv repairs but this is a case with my personal TV which got fried together with many other electronics in my house after a thunderstorm.

                        The TV is a Philips 65PUS8518/12 which had no power. I measured and concluded that the main board was probably fried through ethernet or hdmi. I found a board with same number 715GD328-M0F-B00-005Y (I had G) but from a 55PUS8518. The TV starts but the image is doubled, distorted. I need to set the panel code which is 016 according to the sticker on the back but I can not seem to do it.

                        ...

                        TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
                        by howardc64
                        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

                        Activate power board Philips 40PFH40009/88 tv
                        by spantor
                        Hello partners.

                        Could someone tell me how to make this Philips TV source work without the mainboard being connected? The model of the board is EAX65423701 (2.1) and the model of the Philips TV is 40PFH40009/88.
                        The TV is dead, there is no standby light, however there is a voltage of 12v on the pins ( included 12v VAU ) and 3.2v on the PS-ON pin (see photo) when the power board is connected to the main board. If I disconnect both boards I only get 8 volts on 12v pins. I would like to rule out a fault in the main board by making it work, but so far no one has been able to tell...
