    Samsung pn50b550t2f clicking and sound with no picture

    Hello,
    I have a samsung plasma pn50b550t2f and I was wondering if anyone else has has had these issues.
    With everything plugged in the tv will do the notorious relay click and turn off when trying to power on. After unplugging the x/ y mains and the main board(while jumping the ps) the same clicking occurs.
    With the logic board unplugged the tv will turn on with the samsung tone playing at the start and sound from my input also playing but no display.
    All volts to the main and logic boards are what they are supposed to be but volts to the x/y main boards do not appear to be correct( VA/VS).
    Can anybody advise on what my chances are of just needing to replace the logic board are? Or does this appear to be something wrong with the power supply and/or x/y main boards? None of the caps show any bulging
    Thanks!

            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...

            Samsung UE49KS7000SXXH - fast clicking sound in standby mode
            by B0r1s
            PSU - BN44-00878A

            Symptoms:

            The TV turned itself off, and I haven't been able to turn it back on. The standby voltage was unstable and lower than it should be.
            A weak clicking sound was coming from the transformer.

            Video with clicking sound:https://www.youtube.com/watch?v=lAduhjNtqCA

            Progress:

            After the transformer, I measured four Schottky diodes. DM862C and DM864C diodes readings were 003 in both directions. After detaching them from the circuit and measuring them, DM864C was the shorted one. These Schottky diodes are SB550.I...

            Samsung UN70NU6900F no picture and no sound
            by jchang
            Hi all

            I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.



            Symptom:
            No picture no sound.
            When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
            No sound at all.



            What I tried:
            1. I tried unplugging the left or right ribbon...
