    Re: 40" Philips 40pfl4706/f7 Mother board replacement

    Hi ion4449

    I'm curious to hear if you made any progress with your Philips TV. I have a Philips TV with the same problem, it cycles through the logo screen.

    I got it on Ebay and seller told me that it had been replaced under warranty by the retailer who never bothered to pick up the faulty TV. She said that it worked for about 3 weeks before the fault appeared. I am currently setting up a hobby workshop and I haven't looked at the TV yet.

    I wonder if you have made any progress with your TV?

    Regards


    Barry

        The main board is not turning on the backlight, so the main board is likely at fault. You may find connecting BL-ON directly to 12V using a 2.2k ohm resistor will fix your problem; the screen might flicker a little during boot up but if the TV is displaying video, it should be usable.


        can you show me what two connections you are talking about? I see BL-ON but what should I connect that to?

            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.

            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.

            Assuming...

            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...

            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...

            by boosti45
            i have a 2020 macbook pro 13" A2251 with 820-09149 logic board so i found an issue with chip labeled U6903 according to schem. boardview using flexBV software, so i removed it from the board and the issue im having is that the chip says "07A08FI ELC180​" on top of it but when searching for a replacement chip, i can find tons of identical looking chips that also have "ELC180" printed on them but the first set of digits is never the same so im trying to find out if i need this exact chip with these same numbers as mine and if not which ones are compatible as a replacement?...
