    Okey thanks for your time! I'll sell it as not working/for parts.

      Make sure to note the crack in the panel.

          One last question.
          If i disconnect display from bufferboards is it normal that VS, VE, VA drop (Or should they stay high)?

            It's normal, the control board detects a fault and shuts down the power supply.

            If your X-main is good, at least that is worth some money, as 1080p board is hard to get hold of.

              It seems to be okay because the radiators get warm if i turn tv on!

                If there are no shorts and TV worked before crack, probably OK.

                  Hi Gents need your help please i have the same problem when i remove the ribbon cable from logic board VS,VA and Vsc is perfect.I had the x main blow transisitors and changed them.I believe this is due to VE being 150v DC instead of 85v DC. Please correct me if i wrong i measure the VE from the Y main cable running to the x main at the x main connecting point just to check before i damage the x main again. Or does the x main bring the VE down when connected at testing point on that board.

                  PLease advise

                    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 UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
                    by JJAAMM
                    This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

                    Problem
                    TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

                    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 QN75Q6DRA, No Picture, Has BL, and Sound
                    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...
