    Lg du-42px12x half screen with colored lines/internal leds

    Ok, so first off, this tv had the left (from viewing angle) side filled with colorful lines and the right had a big bar or two but was mainly black. If you lift up on the tv a little the lines disappear but you have like colorful static. And if you leave the tv on about 5 mins it shuts itself off.

    So was told that this would be a controller board issue and it fixed the lines on the right side...yay? (included picture)

    So bad controller board, or hoard of other problems? Oh, the Z sus board also is making a low whur sound right near the IPM.

    Voltages are good from the P/S.

    The main A/V board and controller board both have these internal LEDs. Could someone name there function, especially on the A/V board since some are red. I believe they can be both red or green considering there are 3 terminals per LED.

    Thanks.

    Vertical Lines on Half of LCD Display
    by rfxcasey
    I have an Siemens HMI with vertical lines on half of the screen. These lines aren't scrambled garbage but rather very regular in pattern and color. I have replaced the LCD with a new one and still the problem persists. I'm wondering if this isn't indicative of a bad video process chip or video memory? Any help would be appreciated. The cable appears to be OK but one pin on the header is unpopulated, though there isn't any loose wire to suggest one broke off or popped out of the connector. In the picture below where the connector is busted out of the side, I did that with my small screw driver...

    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

    Vizio M58Q7 colored horizontal lines
    by rapid911
    Hi guys, I have a Vizio M58Q7-J01 and now there are some colored horizontal lines on the screen. Could someone tell me if it's probably a panel issue or something related to other parts and can be fixed? Thank you in advance....

    LCD Tv starts to display black horizontal lines after half an hour of use
    by Gjackson
    Hi, I have a sort of old Grundig LCD Led TV that starts to display black horizontal lines after some use. After it's been turned off for a while and cold it does not display any artifacts however after some use it starts to display some faint horizontal lines at the top of the screen and a bunch in the middle of the screen. The longer the tv is on the worse they get until they become very clearly visible. I suspect that heat has something to do with this as when the lines start to appear i notice that the tv's metal case has gotten warm. Could the T-CON start to malfunction when it starts to get...

    LCD SAMSUNG LE40A656A1CXXE - Vertical Lines on Half of The Screen?
    by ItalianSat
    Hello Everybody,

    I have a 40 inch LCD SAMSUNG LE40A656A1CXXE. Its problem is that there are Vertical Lines on Right Half of The Screen.

    Interestingly enough, when I move my mouse (in the case if connected to a PC) or when I am watching the TV, lines also move. At first appearance, I had thought that the problem might arose from loose vertical ribbons (COF), but when I opened up the TV for further investigations, I realized that the problem cannot be solved by touching them.

    Moreover, I detached the T-CON board for a new round of investigation. I personally...
