    PN60F5300AF no picture with sound no cost fix.

    Samsung plasma PN60F5300AF, TV power on but no picture with sound.
    The big cap in the power supply voltage is 395v, the VS and VA was normal (208v and 55V) at time while turn on, but dropped to 0v after a while. This means the power supply is good.

    Took off the y-sustain board and checked the transistors but non seemed to be bad, no fuse for this board. Checked the upper and lower buffer boards no shorted.

    The Samsung plasma TV is infamous for bad caps in the x y board.

    The problem is the capacitor C5162 (value marked 106) in the y board (LJ92-01958B, LJ41-10331A), see photos. Replaced with a good one fixed. This is the common problem for this model (I fixed 2 in my memory).

    Hope this can help other repair guys.

    Howdy - for me it was C5802 1kv x 331k small blue resistor that was blown. Hard to see as it sits under heatsink. Hope this helps.

        This is not a resistor, but a 330pF 1kV (1000v) ceramic capacitor.

            Guess it's sitting under a heatsink, ceramic capacitor as seen in Lotas's post, if you don't see it, probably is 5082, maybe a typo.

              C5082 is under a heatsink. I have a pn60f5300 which was dead. put in 10uf 50V electrolytic for C5162 (106K). set now powers on but then cycles off and back on after couple minutes. assume I have to replace all the little blue 106K caps on the ysus board

                maybe heat with hairdryer, a couple caps at a time on y-sus, or you could heat more then try to narrow it down, see if the tv stays on longer, I would prolly start with the caps closest to the transformer like the one you switched out C5162 in that area. Usually the electrolytics wear out first but heat all types of caps, see what you get.

                  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...

                  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...

                  what i went through dealing with my mobo with dead onboard sound!
                  by ChaosLegionnaire
                  so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

                  i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...
