    Samsung 40in LTJ400HV05-C LCD : No picture, just dark blue light

    Hi,

    Any idea how to debug this one? When I turn it on the screen goes blue. I've switched it to a HDMI source and there's sound but no picture, just a lit up screen.

    I've replaced the LVDS and two ribbon cables from it (they were both a little charred) but it's the same issue. There's an empty socket on the LVDS board but I can't match it up to anything else so I don't think it's that. Is something not connected? Any ideas?

    Pictures attached. Thank you.

    Samsung UN60F8000BFXZA ~ No Picture or Sound - 5 Res Light Blinks
    by kca
    Hello all ~

    I’m working on this Samsung 60” LED and purchased a new main board a couple of days ago that did not fix the 5 blink issue. The original main board’s HDMI ports (all 4 of them) failed to work and no amount of reflow remedied that.

    This 5 red light blink code on the front panel LED is followed (about 15-20 seconds afterward) by an automatic reboot, and results in 5 more red light blinks. Then the entire cycle repeats itself indefinitely.

    No picture. No sound.

    I tested all the voltages coming out of the power supply...

    Samsung TV`s UE32J5500AK and UE48H6400AK Red Standby Light - No Picture/Sound
    by slimsoul
    Hi, I'm new here and looking for some advice on how to diagnose an issue i have with 2 samsung TVs.

    I have a UE32J5500AK and a UE48H6400AK both with the same issue of red light but nothing happening on the screen, the red light responds to remote or button press by flashing once but stays red. I have searched forums but most turn up a blinking red light.

    I have tried replaceing the power board on the UE32J5500AK last year but this resulted in the same outcome.
    The UE48H6400AK recently developed some small bright areas on the screen, then last week would not power...

    by TR103
    Hi, I have a Samsung UE50TU with:
    - sound and backlight, but no picture
    - when it arrived, it had a picture for a few seconds
    - it keeps rebooting
    - without ribbon cable between the two panel boards, it does not reboot but I have no picture
    - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
    - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

    - without cable between mainboard and lcd panel and with a jumpered...

    SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
    by JJAAMM
    This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

    Problem
    TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...
