    UN55H6350 no picture after start-up logo, won't turn off

    I am working on Samsung UN55H6350 TV. I plug it in and the red stand-by LED comes on. I power up the TV (remote or buttons) backlights come on, I get the "smart TV" logo, it nicely fades away and then nothing. Backlights are still on, nothing is on screen and I can't do anything with the TV. I can't even power it off with remote or buttons, it has to be unplugged.

    It is a main board related issue, possibly with firmware. Samsung firmware update for this model requires me to go through the menu to do it, which I can't do. I tried accessing the service menu, but the TV does not seem to recognize the codes for it.

    Any tips or tricks to try out before I order replacement main board?

    Thanks

          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)...

          Lenovo Y700-17ISK turn on and off
          by pajdek
          Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok.

Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on. Removed power supply, waited...

          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...

          Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
          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...

          MSI GF63 THIN 11UCX (MS-16R6) LAPTOP WON'T TURN ON AFTER RESTARTING
          by RdeveLabs
          To all the members here...

          Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.

          So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But...
