        Is there anywhere I can find a diagram for the tcon board?
        F1 is not busted. Will check U5 now.

        EDIT:
        I cannot check if I get sound output, since tv is unresponsive to buttons and remote.

            All seems fine as far as I can tell. 12 v over main fuse, the large regulator U5 regulates 3.3v to 1.2v.

            How would I go on about resetting sofrware? Sofar I have not been able to make it read update-files (this is when I noticed that it is alive enough to create files on a usb). Do i need to rename the firmware to something specific?

                maybe tom or someone with more experience in this kind of odd fault may have some input ive never really done much on the software side, its odd also the side buttons and remote stop working could one of the side buttons be stuck down causing the remote not to work? can you disconnect side buttons does the remote work then.

                    I doubt it, since I get a distinct "beep" for each press, but I will check!


                    EDIT:
                    Nope, exactly the same with the buttons disconnected.

                            LG 32LG3000 TV, three red light flashes, then the backlight turns on, but no picture
                            by ItepK
                            Hello everyone! I've found this television, and I began troubleshooting it.

                            First, the television kept rapidly power cycling. I've warmed up the capacitors with a hairdryer, and after 3 dimmed red blinks, the backlight turned on, then turned dim, and no picture was present on the screen.

                            I believed that this was caused by a bad power supply producing insufficent power (I've measured 3.5v on the 5.2v rail), so I've blindly recapped the board.

                            After the recapping, all the voltages stableized, however, the issue in the title still remains.

                            I could...

                            Sharp LC50LE752E no picture and backlight, indicator light is lit
                            by roy.zhero
                            I acquired a free 50” TV. IT is a Sharp LC50LE752E. It does not show a picture and has no backlight, although the indicator light turns blue meaning it has turned on.

                            When power is plugged in, the indicator light will turn on blue, the backlight stays off and nothing is visible, even with a flashlight. When pressing the touch buttons on the tv nothing happens. When pressing buttons on the remote control the indicator light will blink indicating the IRsignal was received, but nothing happens.

                            When I hold the force-on-combination it will turn on. It then shows a perfect...

                            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 ‘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 ‘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...
