VESTEL LED BACKLIGHT - repair/replace options ?

[davewtv]

Ok, I have what is most probably the standard problem with these 'beasties'.. namely "Xmas tree wiring" - in other words their dire "one out all out" (series) arrangement !

I am looking at a couple of options to resolve the problem and would appreciate some input as I am sure this has been done before by others on here.....

First question is if I replace the faulty LED on its own (after I have removed the 'mushroom' diffuser) just what type/s of SMD LED would you recommend ? (I assume here it is a 12V LED being over-driven but have no idea of the rest of the spec.) Comments/advice appreciated therefore !

Second question is has anyone re-jigged their panel to some other kind of illumination (for instance 5050 led strips horizontally with a separate PSU or some such) ?

answer 1 : its 3528 Forward Current:400mA Forward Voltage:3.05-3.65V, take look here https://www.badcaps.net/forum/showpo...95&postcount=1

2- i don't tried this, because its unreality solution.

They will work but they are 1w which is too bright snd the light gain wont be even. Best to do the stacking method of repair if you have ever heard of that ?

Thanks RB123 - but I plan to glue the mushroom on top, too ! If 1W is too much what is the correct value ?

Yes, I noticed the "stacking" method, but again this means trashing a whole LED strip rather than just replacing a LED itself.....

It is always annoying, at least to me, when in this "modular" world we have to pay (say) 10 dollars to replace a 10 cent item that failed
(but that could easily be replaced individually)
