    Vizio P759-G1, Tcon issue?
    by EazyBone
    Got this TV free. Guy said it tries to turn on and doesn't. I haven't seen this specific issue before but shown in video. Any way to test the screen to rule it out on these Vizio? Or anyone seen this issue before?

    Any help appreciated

    TCL 50S535 bad tcon or panel issue?
    by x_orange90_x
    Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

    Sony KD-55X9000F TCON Issue
    by thelankanguy
    The TV shows a black screen with no image.
    TCON ribbon connectors were disconnected individually for image and there was no half image even.
    Later both ribbons were disconnected and TCON voltages were tested.
    12V, 3.3V, 1.8V were seen present but VONE signal reads 0V.
    There is also a short to ground in this circled inductor.
    Is this a TCON issue or something else ?...

    VIZIO E70-E3 Half picture with half TCON
    by Fly_Among_Stars
    Hi,
    I have a VIZIO E70-E3.
    Symptoms: Black screen, no picture, but LED backlights are working.
    I probed the power board and voltages are as listed on the board.
    Main board appears fine, too.
    I believe the problem is either a bad T-CON board, or connection to LCD, or bad LCD.
    There are two separate ribbon cables feeding the LCD.
    If both are connected, the screen is black.

    If only the ribbon cable that feeds the right side of the screen (when viewed from the front) is disconnected, the left side of the screen shows picture and...

    BOE HV650QUB-F70 TCON issue - VGH AVDD HAVDD no voltage - caps seem ok
    by cagri
    I have an Arcelik TV with BOE HV650QUB-F70 TCON board, but I think there's an issue with/around PMIC.
    PMIC: iML8940

    There is backlight and sound, but no picture. I watched a YouTube video and turned it off, half an hour later it was dead.

    Input 12v, fuse ok
    DVDD1V2 = 1.2v
    DVDD1V8 = 1.8v
    DVDD3V3 = 3.3v
    VGL = -7v
    **VGH = -0.3v
    **VCOM0, AVDD, HAVDD = 0v
    SWBK1 = 3.3v
    SW1 = 12v

    VGH to GND resistance is 500kohm as expected

    Readings are same after I disconnected the two cables from TCON to panel...
