Re: Samsung UN48H6350 - Going Crazy

Im not familiar with the power button and Ir set up on this tv, but if they are separate, unplug the button setup and use the remote control. This was a common problem on older LCD Samsungs.

Re: Samsung un50nu7100f dark screen right most side.

One thing you can check is if the leds are all lit, (there are 2 sections on each strip), make sure the thick clear panel is reinstalled exactly as it came out. Flipping it or reversing it will cause...

Re: Samsung UN50KU6300 Leds wont stay on

Re: Samsung UN60H6300AF no backlight, brief flash at power up

Re: Sharp LC-50LB261U

Neilc6 is right. Replace all strips with new ones. I have done this series tv so many times and found out the leds have limited life. If you just replace the bad ones, you'll be back doing it again,...

Re: Sharp LC-50LB261U

Yes, your backlight(s) are bad. Replace all of them and be careful removing the screen. It may be glued down. I just did one last week but really dont remember if this one was glued.

Dont use heat. Certain tvs use adhesive to glue it down. I use a .25mm feeler gauge. Its strong enough to slice through the glue and flexible enough to bend over the humps in the frame. Just take...
