    Samsung LE32R88BDX no picture but sound.

    So as above, the back light comes on, T-con tested fine in another Tv yet I have no picture, everything works so it has sound, will select different sources, seems to react to the menu as the back light will brighten up yet I still have no picture, I do hear a slight funny noise which seems to be coming from the main board but after it's warmed up it goes, any ideas on what this issue is? thanks, Andy.

    Check AVDD&3.3V on T-con board - if they drop on this panel could be a bad panel. Also check if T-con is getting 12V at fuse. Have to say I have never seen a bad panel on these.

      Thankfully I have a spare panel so swapping over is no problem, I'll give the fuse a check later. I did read that the PSU could be at fault, I can't really see that being the case but is it a possibility?

        If PSU voltages are OK I would say that is not a problem.

            Thanks for that but have already found it, good info though. So the PSU voltages prove fine so I had a good look at the main board and found IC1108(on the underside very near the LVDS connector) had a nice big crater in the middle of it, quite obvious really so I shall be changing it over from a spare board, fingers crossed I do a good job and that it works, thanks.

                Hello, I have the same issue in my TV, could you tell me which is the IC1108?, because I can´t see in my burned IC.

                Thanks.

                  Lucky for you I have another bad board with this chip, the numbers I see are:

                  4435B
                  BG
                  L74A

                  When searching, the first five digits will give you instant results, I hope you get it working, Andy.

                    Thanks a lot,
                    I'll try to buy, and then I will change it.

                      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...

                      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...

                      by Dodgethis
                      Hello all,

                      This is my first post, but long term lurker on the form learning as much as possible about these TV's. I was given this TV as due to a power outage of constant On/off of power to TV. The TV originally would just click on and off (Typical Reboot Cycle). I opened the back of the TV, and troubleshooted by taking the 96 pin LVDS off one at a time to see if I had a picture on either side. I finally fixed the reboot cycle by finding the error on the left side of the screen off connector CN 1301, and the TV would stay on. Further troubleshooting led me to the driver boards where...
