    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
    LSM340VP01-T01
    I attached few pictures with board and panel

    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.
