    2 Sec to black strange problem

    Hi guys,
    Just to preface this, I've read and followed the sticky guide on this.

    I've got a samsung Syncmaster 2443BW, and it had the 2 sec to black issue. I replaced most of the caps, and it worked fr about 2 and a half hours before reverting back to 2 sec to black.
    Anyone know why this happens, and if there is a fix for it?

    Thanks
    Stu

      Check the Inverter transformers,there may be variation between the resistance readings of primary windings of both Inverter transformers.

          I'm relatively new to this stuff, so how would I go about doing that?

          Heres a few pictures of the board.

              Onkyo TX-SR607 HDMI problem showing a black screen intermittently
              by redwire
              Onkyo TX-SR607 HDMI problem showing a black screen intermittently, audio was OK.
              It would usually cut out a few minutes after power on, for maybe 1 minute then work OK, then cut out and go to black again. Or fade out to sparkles and noisy video.

              Well known is these boards need recapping and there is a strange mix of parts on both sides of the board.

              The bottom of the board has 100uF 4V (5.3*5.3mm, qty 5) and 220uF 4V (6.6*6.6mm, qty 5).
              Per the service bulletin, an issue is the Toshiba LDO's want low ESR for stability so I went with 100uF 6.3V polymer...

              Problem with LG Plasma 60PM6700 - Random power downs
              by theone111
              I have an LG Plasma TV 60PM6700 for the past ~12 years.

              In the last ~3-4 months I have been having some issues.
              1. Problem: It started with random picture disappearing (sound still worked).
                Frequency: Happened about once a week.
                Solution: Had to turn off TV wait a few seconds before turning it on again.
              2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
                Frequency: Happened about once a week.
                Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
              3. Problem: TV shuts down

              Dell Inspiron 7520, LA-8241P mainboard problem, power on black screen
              by dudochnicht
              Hi, i have a Problem with my Dell Inspiron 7520 LA-8241P Mainboard.
              When i start it, all LED's turns on but the display is black.
              Shortly after starting I noticed a click on the mainboard but don't know where it came from.
              I have tested it with the i5 and after the click the laptop goes off but with the i7 the laptop stays on after the click .
              The Dell Inspiron 7520 supports the i7

              What I've already done:
              - start without RAM and it beeps 2 times
              - start without bios battery and it beeps 5 times
              - Press D on start,...
