    Samsung UN46C5000QF Backlight

    I have no picture. Started it with mainboard disconnected. Backlight should light but no backlight.

    I need a schematic and some tips for repairing the back light circuit.

          How about some good clear pictures of the boards so we can see what we are dealing with?

              Samsung QE82Q70RAT no backlight
              by sansanpartida
              Hi everyone!

              Hope you're all having a great day, and thank you very much for stopping by and taking the time to read this post to help me with my parents' Samsung TV.

              My issue: No backlight.

              Model: QE82Q70RAT
              Type No: QE82Q70RAT

              The TV was already serviced by Samsung once under warranty for the exact same issue, but six months after the fix, the backlight went out again. Now, Samsung is asking for nearly the same price as a brand new TV to fix this with the same 6-month guarantee.

              So hopefully, I can fix this cheaper.

              un60j620dafxza - Samsung No Display Problem
              by stylishconsultant
              Hi All,

              Need help.

              I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.

              So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
              problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
              might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard....

              Samsung UN55NU7300F Curved TV. Half side backlight out. Fixed by just removing the rear snap cover
              by howardc64
              TV was fixed just after removing Samsung's rear snap cover.

              This curved TV's construction is rather interesting. When the snapped on back is removed, rest of the TV will relax the curvature. Top of LCD panel is loose as it wants to straighten out against the slightly curved bezel. Snapped back provide most of the curvature shape. So just simple disassembly of rear cover will allow the rest of the TV frame to relax its curvature. Thats probably what fixed it but no idea which connection. 4x LEDs are edge lit.

              Maybe PSU->backlight connector didn't have a good contact?...

              Samsung TV HG46EB690QB No picture, only backlight when disconnected mainboard
              by Henke
              I came across a Samsung tv that does not seem to start up. When i plug it in nothing happens except that the red led turns on. But when i disconnect the mainboard, the backlight turns on and immediately turns back off when i connect the mb again.

              I have tried to disconnect one, none and both cable(s) from the Tcon to the screen but it makes no differens. The PSU seems to work, but when the mb is connected one of the 5V cycles high and low.

              Anyone with inputs?...
