Hi Al, I've been using brush-on superglue to date - it dries quickly with a bit of downward pressure. Comes in a small plastic bottle - a bit like nail polish - and doesn't go off like those little tubes of it. I've purchased some UV glue pens but have yet to try them.

Thanks for the feedback.                            Bruce

Well, I got my chance to trial the UV glue on an LG where the LED covers fall off. It worked a treat - 5 seconds of UV and the glue hardens. It's ideal for LEDs because they're transparent and the UV light can reach the glue spots.

Only drawback is the light switch - it can be easily knocked to the on position and flatten the 2 button batteries inside. Of 4 pens I have, only 2 now work because of this. Now thinking of using a UV light unit from a robot vacuum cleaner, which is larger and can be powered external power source.                                 Bruce

Hi Bruce,

What do you use if you've changed a Led and get a screen halo ? Original holes don't work, so need glue lenses for minimum halo with a bit of the first layer plastic sheet to check.

Tend to use a water based glue, as it's flexible and doesn't contaminate the light path.

The other day got a 50 LG with the issue, but didn't notice that one side flexie was attached to the frame. On gentle lifting it tore off with it's chip - Merde. Seems on the set, all side flexies were attached with White tape, but five had fallen off.

Thought though to sort the Leds for the next time - Chris.

Hi Chris, I get your drift, but on this one it only had the LED caps dislodged. Even so, it seems to me that the caps have some kind of light bias which I haven't comprehended yet The large LG caps appear to have a flange on the top circumference, but the pattern eludes me.

The halo is an irritating problem and yes, best to check each one with the thick sheet in place. At least the cap can be prised loose again and reseated. Have encountered TVs where side tabs are taped down, but my worst one was where the entire bottom of the glass had been glued on.
Suffice to say the Stanley knife worked but I nicked the glass in one spot, and that was the end of that.                             Bruce

Hi Bruce,

Just had a 42 LG where all 32 Leds were duff, mostly S/C. Thinking about knocking up a small oven to the purpose using LMP Lead free paste as guess max 150C will do little harm.

Also had a 50 LG with just one tab taped down. Natch didn't notice 'till it tore off - Life's Good - Chris.
