    L22HD31 resolved

    I don't know if it makes sense to post this here. Maybe if somebody has the same problem it could help them.

    I got this TV set and the picture looked completely scrambled. When putting black tape on the IR receiver the picture gets better (not perfect though.

    The problem was a 680uF/25V on the power supply board. It had only 2.2uF.

    Replaced it, the thing works perfectly well. Nice and easy saturday job.

    T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
    by Tr0ll
    Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

    The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

    Original T-con:
    Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

    First replacement T-con:

    I thought it might be t-con and ordered new t-con from china(supposedly tested)...

    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...

    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 QE55Q7CAM scrambled picture / squares
    by Bloopeta
    Quick question please, not much info or pics to go on unfortunately as its not my TV, and I dont have it infront of me, but was wondering if anyone has come across this before, and what the problem possibly could be?

    Samsung QE55Q7CAM

    Owner states after the tv has been on standby for a long period of time, when switched on, it displays scrambled/blocked image as pictured.

    If one connect cable is disconnected and reconnected or power turned off at the main socket it will work fine with no problems until its been left on standby again for a long time.

    Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
    by Mgiffune
    I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

    I ordered a supposedly ‘new' Tcon board this time, and
