LG 42LB585V - Backlight issue.

<< < (2/3) > >>

They are suppose to, but can be a pain to get out.
Also chekc all the plastic lens, theses type are quite prone to falling off, really poor glue they have used

I owul dalos bridge the connections as have had some where this causes the backlight to go out.
Works fine with tester but the resistance seems to be too high sometimes for the tv to run them..

Hi Sinclair,

There were just too many plastic bits to try bother as Leds can be replaced easily from the top with a snip of the sidecutters, a good clean up with solder wick and glass fibre brush to get down to the copper so re soldering is easier with a bit modified to solder both ends at once with LMP solder.

Hi Zomikula - Thought the larger lenses were easier to glue than the small old ones, but it's only my first attempt so won't reassemble for a day or two, see if they're well stuck. Not sure what you mean about bridging connections - Chris.

sinclairtv:
Yeah I'm doing them like that. Saves trying to get the strings out and possibly breaking them. I also make a note of the way the plastic focus lids go on otherwise you sometimes see a spot from the front if they're slightly off kilter.

zomikula:
They seem to be bit more of a pain
Easier to misalign
You have to make sure the black markins are centred on with the lens.
plays havoc with the back light bleed.
And for what ever reason someon these lens just seem to fall off if you just touch them on some panels.

Hi Zomikula,

See what you mean from the video, as chap seemed to have half a dozen lenses fall off giving white spots and bleed through. Tend to use existing holes, but guess the new Led has to be dead central
which isn't always so easy.

Did my first one with a water based adhesive as it doesn't seem to dry out, though I normally use super glue gel - Wonder what's best ? - Chris.
