    Samsung 46" Lcd tv with whire screen

    Hey all? Long time viewer, first time poster. As normally I find the answers/solutions for my problem with searching the forum, however I can't seem to find and answer for my issue this go around....

    I have a 46" Samsung LCD tv model # la46b610a5r which developed a white screen issue when powered on. The screen starts out dark, then slowly goes to a all white screen. I chanced the tcon board but that didn't seem to fix the issue. Could it be the mainboard causing the issue? Prior to this? The colouring of the screen was starting to go a little off, more yellowy.

    Any help would be greatly appreciated!

    Thanks!

      Sounds like it could be the panel itself or a tab-bond issue....

          Yeah? It is getting old but was good to use in the spare room, was hoping it could be an easy fix, might just be time to part it out or toss it lol

              Can we see the screen shot and the pictures of the T-CON board?

                  Ill try to get that for you tonight (bored at work currently, Figured id post up my question didn't think id get a response right away), I was wondering if its a power issue, as I do know the power supply does make a buzzing sound, so curious if its not producing enough power to power up the tcon? I don't see any evidence of bad caps there either.

                      Samsung UE48JU7000 screen issue after backlight replacement
                      by ScHAmPi
                      Hi all,

                      Because of two bright spots and a couple of dark spots I decided to replace the backlights in my Samsung UE48JU7000. See attached photos:


                      I thought all went well, but after full assembly and testing it out it turns out not all is fine. The backlights are completely fine but I have some weird issues on the right half of the screen. Since I didn't really touch the T-CON board (apart from taking out the ribbons of the display and reconnecting them on assembly) it would be weird that the issue is with the T-CON board... But based on the behavior of the service...
                      The before

                      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...

                      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. ...

                      Dynabook Satellite Pro C50D-B-100 - BIOS Issue, Black Screen
                      by wizard13
                      Hello everyone,

                      I am experiencing a BIOS-related issue with my Dynabook Satellite Pro C50D-B-100. When I power on the laptop, the screen stays black, and there is no response from the system. I suspect a corrupted BIOS.

                      I have checked the forum and the available documentation but could not find a solution specific to my issue.

                      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...
