Backlight LED Replacement tip

[london-freddie]

Not sure if this is in the correct forum but here goes. Changed 3 leds on a 40" Samsung yesterday. did same last week to 3 samsung tvs with no problems, however when all put back together and tv powered up on this set I had 3 distinct bright spots on the screen, these lined up with the areas that I had replaced the leds. Took tv and screen apart again to see what was wrong, fired the backlights up and all seemed ok with them, however when looking at the leds wearing two pairs of dark sunglasses it was obvious that the 3 leds I changed were brighter than all the others. Long story short I had not replaced the clear plastic led covers exacly centred on the leds. removed the led lenses and replaced them exactly in the centre of the led and problem solved.
Therefore when replacing leds make sure that lens cover is exactly in the centre of the led.
Maybe you all know this i I am the only one that has been caught out with this

Thanks for the tip about the sunglasses. Sounds like good practice to test the backlight before putting the screen back together with all the screws and covers.

Very rarely do I solder a new led onto the existing strip.
The stacking method is faster and eliminates the chance of bright spots.
