    T-Con or Panel fault? Samsung LN46B530

    Panel sticker says LTF460HA06.

    There is a vertical about 2" wide white band on top of everything (menu and picture) but I can see through it. There is also 1 green vertical line in the middle of the screen. AND there are black horizontal lines appearing in a random fashion, appararently only after the set heats up a bit.

    Neither T-Con nor panel is not sensitive to bending heat or cold. VGMA voltages on t-con are increasing.

    Any suggestions? How can I be sure if it s a panel or t-con fault without buying a new t-con or opening the panel?

    Definitely panel IMHO. The panel is the only part that discriminates between parts of the picture like that -- the t-con processes the image as a whole.
    Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
    For service manual, schematic, boardview (board view), datasheet, cad - use our search.

      Thanks Tom, I was afraid of someone saying that. :-)

        LG 82UN8570AUD ~ TCON or PANEL?
        by kca
        Hello all ~

        Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.

        When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.

        I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped...

        Samsung QN75Q6FNA backlight no display, red LED blink 2x, fault in panel
        by howardc64
        • Prior owner tried a replacement main board. No difference.
        • Samsung 2x red blinking standby LED = panel fault
        • Jumpered FB_TRDY_1 (pin 1 CN1300 left. main tcon->left side buffer boards) and FB_TRDY_3 (pin 95 CN1301 right. main tcon->right side buffer boards) This allows testing individual T-Con (on main board) connection to panel on this Samsung. Found fault on left side (viewing from rear of TV)
        • Each side has 2 buffer boards, disconnected left side flex between 2 buffer boards. Fault is on the left most board.
        • Tape masking eventually isolated to CN1300 pin 15 (CKV4_GOA) Display

        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...

        TCL 43S423 TCON OR PANEL FAULTY???
        by netgearnetgear
        Good day, I have a TCL TV: Model 43s423. After turning ON the TV, the ROKU TV logo appears with fine lines over the whole screen, then after a while there are vertical bands in the middle of the screen top to bottom and the TV tries to update its firmware but I do not have the remote to connect it to my new network connection. Also the Power ON light blinks 2 times in quick succession. When I remove the ribbon on the right of the tcon board the left side of the screen shows but with fine lines. If I remove the left side ribbon and connect the right side ribbon the whole screen is blank with...
