    Hello!

    Notebook model: Samsung NP-R523
    MB: MODEL: BREMEN-D REV:MP1.2

    When connected to 19VDC, the current is 15-20mA. When you press the button (RUN), the current is 1.4-1.5A. LED and FAN are working. All voltages on the MB are normal.
    There is no image. Connected matrix, external VGA monitor, external HDMI monitor.I have an MB scheme.

          I've done all this. The North Bridge (215-0752007) and the video chip (216-0774007) warmed up (for diagnostics). BIOS flashed. The situation has not changed.

              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...
