I just ease them off with screwdriver, keep them in same orientation and glue them back on keeping them pressed down for at least a minute. Works for me

If you mean the larger funnel shaped ones, there are three small protrusions on the underside of the lens cap. Apply glue and line the protrusions with the holes in the LED strip. Just twist slightly until you feel them mate and click into place with some downward pressure. Clockwise or anticlockwise doesn't seem to matter.

It's all about the birds and the bees.                            Bruce

Hi,

Guess you're assuming new Led placed in exactly the same position as the duff one. If it's a gnat's off, lens issues ensue.

Tend to run backlights with the screen off, and adjust lens using a bit of translucent plastic 'till the halos vanish - Chris.

My replacement 3v leds are all back to front. When I put them in a string it wouldn't light up. On checking, they light up OK but with meter probes reversed. Number on packet is hs23d009 bought from china

Hi,

Feel paiol2 has a good idea - Note Bruce suggested them a while ago. Also note some LG leds have the polarity reversed compared to originals, where they don't quite fit as the pads are reversed. Usable but then then lenses have to re-positioned to avoid screen halos.

Note that Ebay now offers something like the original with the newer smaller Led diode, helping prevent screen halos with original lenses. Otherwise use scrap LG lenses as not too particular about Led dimensions - Chris.

Just had a 60" LG in where about 30 of the LED lens caps had fallen off and a mere touch of the remaining ones caused them to fall away. Been reglueing all 160 caps - these were the chunky ones common in LG panels. All terribly exciting.                                       Bruce

Hi Shaun,

Not replacing the LEDs, just refitting the same lens covers over each LED. When one drops off, it causes a bright spot in front of the exposed LED. If ever you suspect this, just turn the TV on its side and you'll hear the rattle of the dislodged caps in the LED cavity.

Suspect it'd be all automated, Shaun. No jig that I know of.

Just scored a 55 inch Panasonic with the same problem - LED covers dropping off. Unfortunately one of the strips failed during the reglue. Had to lift the reflective white backing sheet. Was glued in place like it was meant to last for eternity, so as I peeled it away it got wrinkled, creased and torn. Made a pig's breakfast of it. Tried to glue it back in place but it was all corrugated and the display looked very patchy to say the least. Plan B next time, if I come up with a plan B.           B for Bruce

Hi Bruce,

We in the UK now have a plan 'C' but nobody knows what it is - Chris.
