changing Direct-Lit LEDs take too long.

[capwizard]

When I change 20 Direct-Lit LEDs, took me almost two day to finish, is there any fast way to do it, the one nobody has parts (LED strips ), need to change one by one, sometime LED's PCB burnt out.....

Anybody has suggestion, my goal is about 20 minutes, I cant sit here all day just changing LEDs , I need my life.

Or this one
http://www.goldmine-elec-products.co...?number=G20736
Or this one is sold out
http://www.goldmine-elec-products.co...number=G21004e
Or this one

Yes, look this

There is another way to fix which I prefered. More green , more recycle, faster and less money.

Look at 24:34 Instead, I use 3M high temperature resistant, heat conducted, Double Sided tape.

Your link for aliexpress is not working says page not found?

Re: changing Direct-Lit LEDs take too long.

Thank you, I corrected

cant without it, when you change dLED.

reference only, 5mm -10mm will be better.

Re: changing Direct-Lit LEDs take too long.

Ok how did it take nearly a day or am I reading it wrong ? Takes me about 20 mins for a 32" lol just need to get used of it thats all.

Re: changing Direct-Lit LEDs take too long.

PCB has white paint so I can't see the copper traces too good, LED polarity keep change also confused me.
Fist I tested 10 LEDs no good, gave A low estimate, end up need to change all LED strips. I do have only need to change one or two LED and fix the tv, over here I mean the DOG.

Now is third day still sit on my bench, but I work over here and there about 10 different items.

in future, when posting ali-express links, remove the junk after "html"
it's your search history & other personal shit.

Re: changing Direct-Lit LEDs take too long.

Yes Sir.Thanks for your friendly reminder.

Re: changing Direct-Lit LEDs take too long.

Premade the dLED universal modules when you need it will be faster. Does anybody have better idea?

PS: the back of LED module has 3M double tape preinstalled.

Re: changing Direct-Lit LEDs take too long.

TV is working finally.......

Pic2 is the parts has been changed. TV is UN46FH6030FH

PS: You know what just right now, came in the similar one has the same problem UN46EH6300. Oh... my God!!!

Re: changing Direct-Lit LEDs take too long.

Can I use mini spot welder to save time of tedious wires jumping?

[sam_sam_sam]

Re: changing Direct-Lit LEDs take too long.

You could use a battery spot welder if you modified the amount of time or current to do the welding you would not need very much time or current

Or you could make one out of a microwave oven transformer and a time controller and a set of battery welding stud pins if you want to make one send pm message and I will try to help you make one it takes a little time to make one I made one but I have not made a case to house all the hardware

Here is what you would need

A modified microwave oven transformer or find broken microwave oven on the side of the road or dumper diving
A mil-second timer
A set of battery welding stud pins
And battery welding strapping very narrow very thin

All of these items can be bought on eBay

Thank you very much for your inspiration and Sorry for the holiday delayed response.

the problem is that too heavy for my project. So... my idea is hand hold device, use Weller solder gun (only has AC 1.2 v output),diode and caps(3300/16v), I called this " suicide bomber"(pic 5)........Can anyone help with this project? How many caps and Watt-seconds will be need? .....................

Thank you, I need A simple one and this one you gonna need gloves too...

PS: the Weller transformer act as A current limiter.

It is going to be trial and error
The first thing to do is the soldiering gun with out any caps at all then see what you get also take voltage reading so you what voltage caps you need I would start with .5 fards capacitors and see what results you get if it does not weld hot enough then jump to a one fard capacitor until you get the the results you are looking for

Also once you get the right results then you need a mil-second timer or use a SCR driver controller to give you fine adjustment control of your welder to weld
