Anybody changed tv backlight leds with success?

The tv at at holiday home (LG, 10 years old) packed up (went dark, could
just make out the picture).

Ordered led strips from Ali. Strips arrived from China.

Took tv apart. Now in bits all over the garage.

Go to install new strips - wrong. Wrong size and don't line up, wrong
connectors etc.

Thought it worth a try as the strips cost 12€. Now returning them. It
looks like a proper set may cost 5 times that.

Question is: is it worth it? And yes, I'm assuming that as there are lots
of volts at the connector, it is the leds at fault.

My usual rule of thumb for this kind of thing is: is there a video on
Youtube? Does it look easy enough? Does the YT description list the
actual parts to buy?

The last bit is usually the decider!

This is what I bought:

0.0.4dc343e0NUpelG&gatewayAdapt=glo2esp

Looks like originals are about 70€.

Taking it apart was messy - but not difficult.

I'm as willing as the next fellow to DIY with electronics, but TVs,
to my mind, are pretty cheap, considering the quality you get nowadays.

I'd imagine trying to refit LEDs behind the screen will probably end up
with a bad picture and a waste of your time.

369 Euro including VAT for a nice 43 inch Samsung 4k TV at
https://www.mediamarkt.es

Has to be cheaper for a no-name HD resolution unit...

Deciding factor for me in such a situation is whether there's enough room in the bin.

Done that. We had guests due in, so couldn't mess around. Spent 350 at
Carrefour. Now I have a garage full of bits of 10 y/o tv.

And the guest tells me that in 8 nights, they didn't even switch the tv
on.

I'm tempted to bin it as a) it would only be a spare and b) being quite
old, anything could break next.

I strongly recommend just chucking it out. Not worth the space it
takes up and you probably don't need another project for that mythical
future day when you find yourself casting about for something to
while away the time.

It's hard for me to throw anything away that is potentially useful.
I've come to realize that, just like for a business, keeping inventory
around has a cost associated with it. For me, that cost is storage
space, I'm literally running out of places to put things.

Which gives me an idea, I'm now going out to the garage to fire up the
angle grinder, I may be some time. Maybe I will free up a spot to set
up the 3D printer I bought a few years ago but never assembled. Or, I
might get just as much enjoyment out of throwing the damned thing away!

You could 3D print a dustbin and put it in that.
Or print a new garage?

LOL!

> Or print a new garage?

I do have a 22 m^2 shed in the planning stages, the "2 car" garage
hasn't held two cars since the motorbike count reached 4... Lucky to
get one car in there in the winter, come summer, bikes and the bike
lift take priority.

At this point, I knew it was not going to go well.

Does no one think on the children/environment?

Don't throw anything away. Experience teaches us that having kept a
perfectly good gizmo in stock for 30yrs, the moment you bin it, you, your
neighbour/brother/mate is going to need one about a week later and ends up
having to buy one.
That moment when someone pops round to enquire if you happen to have a rare
mk1 arbilator in the shed. In the ensueing 3hr rummage, you can't find one
but you DO find that adapter you searched for in vain last week :-)
