    Samsung LCD LN40A550P3FXZA, no picture!

    Samsung sent a tech out to replace the motherboard and capacitors for free. It worked for 2 weeks and now is doing the same thing as before! It's soooooooo frustrating. I am looking for people who are experiencing the same issue as me. I find plenty of people who had their power board and/or capacitors replaced with it working fine, but not like my TV; it went out again and does the exact same thing. Symptoms are blinking stand by light, black screen until it comes on then vertical lines (unable to see any pic), makes a loud high pitch noise at times. I took the back of the TV off and the capacitors are fine, not bulging, etc. Any ideas? I would appreciate any feedback or assistance. Thank you for your time! Let me know if you need additional info and I will get it to you stat.

      Yes. Remember, it is Samsung's problem to fix. You should not have to fix this. Samsung screwed up, so Samsung must fix it.... and don't buy Samsung again!
      Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

        They should have a warranty for there work.
        I think is the mainboard the problem.
        I have one of these in my bedroom and it was only the capacitors that needed repolacing and it works great.

          Put the rear cabinet back on the TV and call Samsung back. They should stand behind their work, but when you get into the set behind them, they have every right to void the guarantee on their work.

            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...
