    Toshiba 43L3763DG Has sound and backlight but no picture

    Hello, this TV has sound and backlight but there is no picture. I have 12v on the T-Con fuse but on the flex side there are no voltages. Can anyone help?

    Please provide good clear pictures of the whole back side of the TV showing all the boards and also straight shot of the whole T-CON board so we can see what we are dealing with, please use 'Go Advanced' to attach the pictures.

        when you say "no voltages on the flex side"... what does that mean? list which ones that you have checked. One other test, if you disconnect, one cable at a time, the cabling going from the tcon to the panel, what is the resulting display?

          I removed the right flex and the side of the screen which the flex was removed turned white. Put it back in and removed the left flex, the screen was all black though, not white like with the other flex.

            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...

            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...

            Toshiba 55lf621c21 Dim Picture / Backlight afterbypassing a Burnt LED
            by willis6732
            Hello,

            This TV came in for a backlight Repair. I bypassed the Burnt LED as shown in Picture. I thought it was fixed and returned to customer. So I dont have the TV anymore, but customer says its not really watchable.

            Now the TV Is much dimmer than before. It does a quick bright flash when it first turns on.

            The Driver board looked pretty toasty in the LED Driver Area.

            So I am wondering.. how can i Tell if this is a LED or Driver Board Issue?...

            Missing LCD Panel Voltages VGH, VGL, VCOM (TCL 55P6US Sound & Backlight but NO Picture)
            by maneatingmonkey
            I have a TCL 55P6US with sound and backlight but no picture. This model does not have a T-CON board, and the right (rear perspective) panel board is fed from the left panel board. I have not been able to induce any change by disconnecting the secondary panel board or the tape cut-off method on the primary board.

            There are a bunch of voltages missing on the panel boards. I can't find any shorted caps of the panel boards, and all of the missing voltage rails read in the kiloohms, which leads me to suspect the issue may lie on the circuit board, rather than a short in the panel.
