                    Probably means that the lcd screen is fucked and something on it is shorted try taking the bezel off and see if there are any obvious exploded parts on the tab section of the lcd. Also maybe you do have sound but not on the correct input.

                      OK got this tv apart again, put a mp4 film on a usb stick in usb slot, audio is now there, so I do have audio but I still have no picture, just the backlight
                      Connected via HDMI and Scart cables to a working tv no picture is displayed on the working TV, so I may be wrong but that is now telling me that there is no video output from the mainboard.

                          yes have replaced it twice, I have now got its original mainboard in the set that was in when I got the tv.
                          I am now sat listening to the sound from iron man film but no picture on the screen, and no video being sent out via scart or hdmi, I am stuck on this but am convinced it is a mainboard fault. \just a thought of mine maybe the mainboard in the set is not the correct mainboard, I do not know if it had been changed before I got this set, I have replaced the board with the same number as what is fitted now, however, looking on the web there are several different mainboards for sale for this model of tv with different part numbers. If that makes any sense to you

                            Does SCART\HDMI output work if you disconnect the panel?

                                maybe also if you havnt look for any burnt parts on the panel board there may even be a fuse on it i havnt really looked on these boards before.

                                            The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume. Something about putting it into Stereo mode is causing the volume to drop significantly and I can't figure it out.

                                            The player processes the audio signal using two different reference frequencies. The "R"...

                                            Hi,

                                            My barely 3 year old TV has stopped displaying video, although the video output comes for a few seconds after turning ON which displays the manufacturers logo then shows the home screen (all this with some blue flicker) then the video goes blank and the screen is dark blue with the backlight on. The audio output works perfectly and the TV also takes in voice commands(smart TV).

                                            The TCON board has the following Chips -
                                            Samsung VTU63A0
                                            RT6939 - 2nos.

                                            and all these chips are getting real hot within a minute, I dont know if this is normal....

                                            Hi all,

                                            Ok so I have this beautiful un55h8000 samsung tv with sound but no video nor backlight. When turning the set on the red light blinks 5 times.

                                            The screen shows no damage and backlight turns on when I disconnect the power supply from the main board. The tcon board only has 2 out of 3 leds on.
