    Samsung le32r86bd - Artifacts on the TV screen

    Hi all.
    I have trouble with my old TV.
    Here is a link with video:
    https://www.youtube.com/watch?v=DcurGmfC-9E

    Description of the error:
    Artifacts on the TV screen
    Self-restart TV when it is on
    After 2 minutes errors will disappear and TV play OK.

    I tried replaced all electrolyth caps on power board: BN44-00155A,
    And then I removed all bad glue, but no changes.

    Parts RM801 and CM810 are OK.

    Clean and re-seat cables going to and leaving the T-CON Bd . Re-seat all other connectors on Main Bd and PSU. Clean using iso-propyl alcohol.

      I think there may be bad caps on the main board. Take the back off and heat up the main board with an hair dryer to like 40C. Turn the TV on. If it does turn on instantly, there are bad caps some where. Also check for caps underneath the shielding.

        Same old story, common problem on mainboard Bordeaux plus. Change all 4 electrolityc caps 1000uf on mainboard, 2 outside 2 under the shield.

          Bingo!
          I change only 2 electrolityc caps 1000uf on mainboard. Access to 2 electrolityc caps 1000uf under shield is complexity.
          Shield is soldering from bottom side PCB on 8 points. I was lucky and the problem solved.
          Thanks all for solutions.

            Don't sing victory, the caps under the shield must be changed, probably in the near future you will have to open it again. Need a powerful soldering iron minimum 40w, solder braid.
