samsung prisim sheet

<< < (2/2)

Turnip:
Had a Sammy where replaced duff strips with individual diodes on small boards.
Took ages, as all hard wired.
Could see every diode, so sorted a diffuser from a scrap screen, cut to size and
shuffled it to fit.
OK, but wouldn't do it again. Set needed an extra diffuser than provided to sort the
picture - Chris.

Alas for the MU, NU, KU, TU and JS series where the diffuser gets cooked. The diffuser is directional, allowing more light to reach the top and less at the bottom.
If you rotate the sheet (Do not flip the sheet over) so the burn marks are at the top, it will result in a picture that's OK at the bottom but gets gradually darker towards the top.

One solution I read about seems productive but not necessarily profitable. It involved using a dremmel to clean up the burn marks, but when fitting new LED strips, move them 1 to 1.5 cm sideways, so that each LED ends up between the burns. This requires some cutting off to the extreme end stop for the strip, as well as the recess for the LED connector.

The last one I did was without modification. Ended up with fair to middling result, so it was a take it of leave it situation.  Bruce

Wish Id read the last post before I rotated the sheet and discovered exactly the symptoms you described :03:
