    Toshiba LED TV 40L1333b sound no picture

    Hey guys. This is my first post, so please be gentle! My Toshiba 40L1333b LED TV has sound but no picture. I used a flashlight in the dark and the picture is barely visible. It's about 1 year old.

    Can we get good clear and focused pictures of both sides of the power supply board?

        Please provide the focused straight shot of both sides of the board, I need to be able to trace the connection and clearly see the components and traces, thanks!

          Vestel design set, not made by Toshiba. What's the part # on the power board? (17PW... or 17IPS... usually)

                  So lads. I've never opened up a TV before so schematics and the like is pretty much double Dutch to me! In layman terms what's the problem and can it be fixed?

                    Do you have a digital multimeter available to do some tests?

                      Perhaps you need to do some reading? There are more and more threads re led
                      tvs with no back light - weak point seems to be the led strings either burnt out
                      or a wire trapped and eventually shorting however it may not be a quick fix.
                      Try and learn some of the names of components on the board.
                      Pictures really are not clear enough- for trouble shooting they need to be clear enough for us to read the board part numbers
                      Here is a recent post - not yet solved.

                                Common issue with these Panels is the little connector blocks that link the Led strings break down and fail so you need to bridge them over with solid wire and then test the Leds.

                                  Thanks

                                    Maybe follow the thread, and watch the video I linked. Common issue with that chassis is the connections between the Leds breaking down causing no backlight.

                                          - 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.

                                          Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture

                                          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

                                          Hi Everyone,

                                          I'm working on a Toshiba 37AV500A Regza TV.

                                          The issue:
                                          TV was working picture and sound went out. Green stand by light stayed on, It will respond to the power button being pressed (goes in and out of standby)
                                          The TV will very intermittently work for around 40 mins then stop. This doesn't seem to matter if its hot/cold unplugged for a while etc.


                                          I checked the PSU voltages and everything looked good.
                                          No bulging caps or signs of heat.

                                          24v aud = 24.41v
                                          12v = 11.98v
                                          5v = 5.062
                                          p_o/f = Goes high...

                                          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...
