I use 5 second fix, It's UV reactive.

Re: reflectors have fallen in tv lg

Thank you for the useful information, Mr Liota
how do we clean the reflector with pure alcohol?
there is no risk of damaging the plastic;
In addition, this method is very good, but my product will run out of china to the best in a month.
While I can find the B7000 now, are you stuck with it except that I will wait for an hour or is it prohibitive?

Re: reflectors have fallen in tv lg

you can buy the 5 second glue on ebay or amazon etc b7000 wont work long term (i have tried it once) hence changed too the uv glue also makesure you refit the lenses on the exact marks they fell off (lenses i did had 3 mounting lugs so made it easy to re align them other wise you have bright spots on the screen if you fit them in the wrong position)

Re: reflectors have fallen in tv lg

perfect
If I only get this product https://www.ebay.co.uk/itm/5-Second-...RoCnfEQAvD_BwE
because I put the translation from Russian but to be sure the light on the back is enough to stick the reflector it just takes more time than using a regular uv lens;
and one last thing I reflected it to clean it from the old glue without damaging its plastic
what material can we use?

Re: reflectors have fallen in tv lg

On these LB/LF series strips, I just replace them all with new. All the lenses are likely loose and need to be aligned perfectly or will cause bright spots. The LEDs all have wear and may fail in the future. If you have the panel off, you don't want to go in there a second time when the LEDs start failing.

B7000 is good?

Should be good. It's not 5 sec, maybe 1hr.

Re: reflectors have fallen in tv lg

sorry and one last thing i forgot to ask
can i look at the solder when I glue and illuminate with the ultraviolet lens
there is a danger to my eyes and I have to wear sunglasses for example

Re: reflectors have fallen in tv lg

I use a scalpel to remove just a little of the old glue.
The UV LED points away from you.

Re: reflectors have fallen in tv lg

as diif suggests i just use a scalpel etc too remove the old glue if needed and yes uv points away from you so alls good it does say five seconds i always leave light on each mounting point a bit longer about 15 seconds just to make sure they bond.
