      What do you mean inside layer?

      If the LCD is cracked its cracked.

      Difference with LED is just the backlighting

          The LED layer itself is the front layer its around 3-5mm in thickness. Behind that is just a plastic sheet that is used as a diffusion material for the led's to spread the light uniformly. There are then lots of acetate type layers behind that. It would be possible to transplant a working LED as I did using a set with a failed backlight but these are much harder to source than those with broken screens. I was lucky that I had a failed backlight, had it have been a broken screen the TV is near worthless.

            UN65TU700DF picture and sound but no backlight. BL tests ok but repl. PSU didnt fix!
            by triplefour
            this tv is throwing me for a loop. do samsung tvs no longer have the backlight self test feature built into the power supply?
            i tested the backlight with my LED tester and it lights up both strips. one of them reads 100v and the other reads 63.7v.
            unplugged mainboard from power supply but left backlight plugged in, and then plugged psu wall power in. expected to see backlights light up but see nothing.
            according to how ive diagnosed in the past, this would almost always be a bad power supply. replacement power supply was cheap like 20$ from ebay. but still i get not even...

            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...

            Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
            by Mgiffune
            I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started β€˜fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

            I ordered a supposedly β€˜new' Tcon board this time, and
            ...

            Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
            by Ierwin
            Hello everyone,
            Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
            The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
            He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
            I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
            Anyway I still fully expect that there has been something seriously damaged...

            Philips 50PUS7363/12 Backlight but no picture
            by groomit
            Hi,
            I'm having trouble with above mentioned TV. Bought it defect.
            Picture was heavily compressed around the horizontal axis. Fiddeled and tried different things (mask clock lines, swap T-Con). But no difference.
            Then I identified a heating capacitor on the left hand Signal-PCB (?) below the display. Replaced it by hand soldering. Checked for shorts afterwards. But now the screen stays black.

            I can see backlight, but screen stays black.
            What I've tried:
            - Disconnect right side cable from T-Con -> same (backlight but no pic)
            - Disconnect left side...
