    Phillips 47pfl7403d lower half screen flicker

    Supposidly fixed this set or so I thought. Tv works flawless for roughly 2 hours then the lower half of the screen starts to flicker in and out. Picture is still there its just dimming in sections. How do I access service menu on this set? Tab bonding issue or should I look at the power supply?

    Samsung flicker - BN44-00932T board or else?
    by fixit007
    I picked up this TV that the prior owner said - just died.

    Tested the fuse - burnt. A dead capacitor is visible too on the hot side (CP801). Got the replacement power board (cheaply - used). Replaced the board - the TV turned ON!

    Now, about a month later (yesterday) I noticed the left side of the screen was flickering from time to time. That was already happening with the antenna input, not through HDMI.

    Also, some glitchiness with a Fire stick on HDMI3 - I hit an app with quick dark screen in stick, the TV goes - no input. Then I had to choose the stick...

    TD Systems K50DLG12US half black and half white screen
    by Raulnn
    good night! I have this screen that looks half black and half white. the tcon gives a low vgh value (5-6v). the rest seem fine. I first removed the flex from one half of the panel and then the other. Removing the left, vgh increases it to 25-26v. I think the problem is in that area, but there are not many elements on the integrated controller board. there are no shorted capacitors. could they be a cof? Some help?

    By the way, now the entire screen is black. Maybe some flex was not connected correctly... I have exchanged the flex and there are no variations, I don't think they are the...

    ACER BM320 Monitor - Horizonal Flickering Lines After a While
    by reessi
    Hello,

    The monitor started off showing flickering thin (1 pixel) lines horizontally every say 3mm..

    They are black on the right and gradually fade to nothing on the far left.
    They start either after 5 mins or up to 2 hours after so annoying for testing.
    They flicker continuously very fast! With a slight pause milli-second every second.

    Initially I cleaned the LVDS cable and connected to the T-Con and then it worked fine for 3 weeks but not sure if this was just co-incidence.

    I tested each half by removing the first the left flex from...

    Samsung UE46F6500SDXZT - Lower half of screen moving purple lines.
    by GobonTalBzar
    I have a Samsung UE46F6500 SDXZT with the bottom half of the screen showing purple lines and sort of a lower resolution. These lines appear and disappear in response to motion on any part of the screen. For example they will appear below any popups (no signal etc) and moves sideways to stay below the location of the popups. Screensh1.jpg and Screensh2.jpgshows the issue and Samsung_Problem.zip is a video of the issue as it happens.

    I've tried replacing the TCON board but nothing changed. Wiggling the connections doesn't seem to affect anything on screen.

    I've attached...

    UN65TU7000 strobing / flicker
    by howardc64
    Good picture but has ~200Hz+ faint flicker/strobing over entire screen. Also has a single green vertical line. Can mask out t-con signals (2pins) to stop flicker/strobing but 1/12 of screen will be all colorful vertical lines (single green vertical line is in this section)

    Since can mask t-con signal to disable part of the screen and stop flicker/strobing. Obviously not backlight.

    Panel has 4x driver boards each responsible for 1/4 of the screen. 3 tabs on each board. Each tab responsible for 1/12 of the screen. the 2 outer most tabs has additional horizontal gate control...
