    Samsung Plasma TV Model PN50A550S1FXZA

    I have a Samsung Plasma Model No. PN50A550S1FXZA, S/N B46V3CQS101329V. I heard a loud pop and now I have no picture. The sound appears to work, but no picture. I disconnected everything, and took off the back. I did not notice any capacitors which were blown or bulging. Also, I did not see any fuses blown. (all white fuses and appeared to be intact) When I power on the tv, I hear a one big click and hear the Samsung start up tones. Still no picture. I tried the menu on the remote and it will not show anything on the screen. All black. Can you help me diagnose the problem? Some of my internet research suggests the Y sustain board.

    I am a novice and would appreciate any help. Thanks!

      If you can, take some pictures and post it so that everyone can see how the TV looks inside

              Y Sustain is a good bet. Remove it from the set and check the fets under the heatsinks for shorts.

                  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...

                  Samsung QE55Q60RAT - no picture
                  by YellowJacket
                  Hi friends,

                  a friend of mine gave me this TV to fix, with common SAMSUNG TV issue - damaged panel. Turning on, sound is present, but no picture. So I went directly to standard process, connecting two pads together with a wire ( see in the picture ), and then removing flex cables. With right flex connected, there was half screen working, but still no picture ( disappearing colors and similar weird stuff ) + working sound. With left flex connected, TV is restarting + working sound. I supposed, left side is damaged, so I then blocked all 8 CLK pins ( going from 0R resistors on the second...
