    37 inch Philips LCD No picture

    Hello Everyone,
    All of the sudden the other day our TV screen just went blank. I have the service manual for this chassis but so far no joy. I have been able to get the power light to flash a code of some sort with the remote control. It just flashes a long blue light then off, it never changes or seems to finish. I had luck on my daughters plasma a Visio 42 inch when the power up board was clicking I replaced it and bingo. But with our LCD nothing so simple. I understand the standby and power up steps but am not sure how to reboot or get it out of a protection mode if that's what is wrong. In sort not sure what to do short of replacing a board at a time. There is a place to connect a tool to interface with a pc, but do not have the tool. If anyone has a similar problem and can point me in the right direction it would be very much appreciated. Philips model: 37PFL5332D/37. Chassis no. EJ3.OULA (i have that service manual). small board number: 3104 313 61734, power board PLCD300P1, part no. 3122 423 31812. Thanks.

      Note the links in my signature for information on the proper way to attach pictures.

      No not post them inline, it slows down the loading of threads; use 'Manage Attachments'.

      When referencing the model or chassis number, spell it correctly. It is EJ3.0U LA

      Unplug the power for several minutes to exit protection mode.

      There are several possibilities; bad power supply, bad main board, backlight failure. You don't give me the information to eliminate anything.

      A couple of tests: With the back removed, watch the back of the TV while you turn the TV on. Is there a flash of light from the backlights? Hook a known signal source to the TV - a DVD player, video game, etc. When you step through the inputs do you hear the sound from the source? Can you see a dim picture when you shine a flashlight on the screen?

      Measure the power supply output voltages after it's been turned on, but before it foes into protection.

      For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

      Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

          Hi,
          Thanks.
          I found the problem tonight. The LCD inverter board to the left of the power board had a burnt spot with arc to chassis, also the caps were bulging. Thank you though.

              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...
