    Samsung UE50J6150AS BL_TON OK Screen only little corner lighting up

    i got this TV today.. as you can see the screen LCD had only at the corner lighting up, the other round light spot are lens falling down on LED as i can hear it when i move the TV.

    i tell the truth i never seen this before.. LED BL yes are little blue but i don't thing it related to this issue as i suspect the T-CON, i saw before T-CON when it work the 2 blue LED on it will lit on.. here only one. even i tested the led and its fine.
    voltage on T-CON F1 from both side for me little high 12.55V ( could be indicated open / not complete operation on the T-CON.

    disconnect one ribbon at time no any white half screen only corner spot will disappear when i unplug the ribbon on its side. so it tell me this is from LCD the sport was not from BL

    disconnect the BL socket from PCB and turn on... it turn on only no BL
    disconnect the MB from PCB , BL come one at same level when they work at time

    i feed HDMI signal and hearing the sound and BL level change regards the video sync. no sigm on any picture on screen

    any one have this issue before or read on it.. please remember this tv had no Internet LAN or WLAN. and beside the blue of BL option to replace T-CON are out from the table.
    thanks.

      not sure, but a guess is being a samsung, could be most of the backlights are bad.

          You may have several problems. I would sort out the light problem first. Panel or diffuser
          I assume no responsibility for any stupid suggestions I might post.

              thanks for the response.. yes i agree. 3 fault i can tell
              1- blue LED BL easy
              2-T-CON toasted only VDD VCC read fine. VCOM wirh out ribbon connected 0V with ribbon -1.40 VGH less than 2V
              3- Panel shorted which toasted the T-CON.
              will keep it aside for the future if i my hand got on T-CON or to try the panel for different system.. lol.

                  Would be interesting to find out what is causing that bright spot in corner. All LEDs are lighting up?

                      yes all lighting, only one LED lost the lens and found it under the hard reflector

                      bright spot at corner are just view LCD cells turning on.

                              Samsung UE55JU6800K half screen dark
                              by Chrissygizmo
                              Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
                              I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...

                              Hello everyone,

                              I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...

                              samsung galaxy ao2s very temperamental after screen replaced
                              by Chrissygizmo
                              Hi , I've recently replaced the screen in my Samsung galaxy ao2s, at first it wouldn't even turn on, it had the charging symbol on the screen when plugged in but the green circle wasn't going around to show it charging....
                              Ive eventually managed to get it on and working but it's very temperamental...

                              The battery icon always reads as 50% , when the phone goes into lock screen mode i sometimes can't get the screen back on unless I plug the charger in to get it to light up, also it keeps putting the camera app on.. u think it could be something to do with the side buttons. ...

                              Samsung LH82QENELGC/EN Help needed - Static line on screen
                              by Kiberge
                              HI guys!

                              I've got a Samsung LH82QENELGC/EN with a problem and need some advice and I hope this is the forum to use?
                              I'm from Norway so I'd like to apology in advance if my description of the fault is kind of simple or the names on the components are way off. 😊

                              the TV is powering up, working as normally and picture is all good, except a 1.5-inch-wide vertical line of snow/static across the screen.


                              This TV is a Signage Display/Public Display version and it's been used at my work for 4-5 years showing commercials 24/7. The fault occurred when...

                              Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
                              by Ryan.man
                              Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

                              My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

                              This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...
