    Philips B line 342B1C

    Hi guys,
    I have a problem with this monitor. Initialy when it is turn on backlight is on but no image on screen. Opened the case and check T-con board 12V present from the mainboard and 1.8V on another auxiliary source .T-con board has 2 parts main one with power supply and chips and a second one ,connected with a flex cable, with few capacitors. I disconnected second board and I got half screen with picture.
    I suspected one chip from the ribon flex with issue.
    Any help ?
    Codes from broads 19Y_34FP_LH42MQXSR_V01_HF

    Thank you

      I forgot the mention , without second board connected I got on the main board all voltages 14,90V 7,5V and 1,8V .
      When sendary board is connected 14,90V and 7,5V are 0V.

          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...

          Problem

          This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

          Philips 70PUS7855/12 bad colors when applying the tape fix on teh T-con board
          by silikon77
          Hi!
          Got an 70 inch Philips tv model 70pus7855/12 from scraps and I decidet to give it a go. I'm an enthusiast but no porfessional in the electronics.
          Found some advices watching youtube nad came up with this:
          It came with no picture, after diagnosing it I found out that the right side of the T.con board was faulty.
          I taped down the clock signals and I got a picture but the left side of the panel has less pronounced colours. Only the right 3rd side of the panel has good colors.
          See attached picture.

          I tried a few combinations to block individual clock...
