Re: Post The Led Backlights Your Fixing Here.

well flocko says
If they are the large LG lens Type they will not light with meter in diode mode? they run at 5.5-6.00 v

so if this was my set i would probs take a chance.

2 leds did glow with my fluke meter and then retested with 3 x AA cells and even the ones that glowed looked odd they seem to be dual led in 1 package as one lit on left hand side and the other on the right so i guess the 2 glowed as only one was working in each led package (if you get what i mean)

Re: Post The Led Backlights Your Fixing Here.

The good news is you have worked out how to test the LEDs. The not so good news is I am out of 32"strips only 42" +49" left in stock. but still have some LEDs in stack repair kits

At that price they are cheaper than led strips but harder too change i guess, but hey its worth just trying a couple and powering the set up and see what the colour/brightness match is like.

hi Vince i have ordered 50 theres only 2 out of the 18 leds that actualy half work theyre dual chip led's so i dont think matching will help much im aiming to replace all

Re: Post The Led Backlights Your Fixing Here.

dual chip? never heard of that in the diagram there two diodes in each of the leds that you have ordered so is there two leds in one sorry for questions as never heard of dual chip leds.

on the 2 leds i checked that half work one lights up on left side and the other led lights up on the right side and you can see its half of the led, yes as it seems there is 2 led chips in each led assuming this is how they get the 6v in one package ?

Re: Post The Led Backlights Your Fixing Here.

A lot of edge lite strips also have the two LEDs in one case,and also run at 5.5-6.00v but have an oblong case. and can be hard check as you need to just have a large enough voltage to turn them on without it blinding you

Re: Post The Led Backlights Your Fixing Here.

They make DUAL-LED in one package in many form factors with LEDs in series (6Vf rating due to two white LEDs is series), they also make DUAL-LED connected in parallel, Vf 3V.
See example PDF.
