Hello! in the previous video we saw thecomplete procedure to install the New LED strips on an LG brand TV here is the link for those who do notThey have seen now i'm going to show you how to replace the LED strips on a 40 inch Samsung smart brand TV actually change the LEDs onmost televisions are very similar however in some modelsthere will always be details that may be relevant or some complications arise as in this case the LEDs burned and damaged the light diffusing acrylic sheet and the white reflector in the background I did not find the same parts, but I will show you how you can fix it this TV had already been changing the LEDs a year ago and used LED strips were installedfrom another television of the same model because in that time they couldn'tget new parts the good news is that now I already know where to buy them here in mexico and currently I have been able to findof various makes and models If you are from Mexico and need New LED strips for your repairs and you are interested in this information leave me a comment or request it to any of the emails appearing in the video description if you are not subscribed to the channel yet I invite you to do it and activate the notification bell so that you get the warning when I upload a new video ok let's start here I already have the new spare parts forthis TV model they came fast just a couple of days after ordering they look good but you have to try them for this I will use the universal testermade in a previous video the link is on a cardfor those who want to see it ok all are well To remove the back cover of the TV I must first remove this small cover and disconnect the sensor cables and the control buttons with this I will avoid causing any damage when removing it now I will disconnect the cables and removethe screws that hold the cards I disconnect the speakers and this flexible .

.

.

in this way now the other end, I just press on the sides and halo up I will proceed to remove the screws that's it .

.

now to remove the cardMain I must be careful and not pull hard since from the backhas a piece that helps dissipate heat and it normally adheres strongly to the sheet here you can see it I will remove the power card, withouttouch components to avoid shock speakers just pull out and out easily here it has a metallic armor .

.

but it doesn't have it, I'll just remove these screws that hold the T-CON card ok .

.

already onlyI disconnect the flexible so and I withdraw it these metal parts must be removedto access panel cards the supports of these cards arerigid, not rubber like other models and to avoid damaging these cards when handling the TV I'll just leave them a little out of place here you can see .

.

.

they are already free now i will turn the tv I remove the plastic frame and took out the cardsthus I will fasten them to the panel with double tapeface and now I can remove the panel .

.

.

I will do very carefully now the other plastic frame and thelight diffusing sheets I found some totally burned LEDS and they damaged the white reflector and also the acrylic sheet some holes were made .

.

.

the damage is irreparable and must be changed the other sheet was not damaged you can use the same here we can see more clearly the partsburned I'm going to remove all the LED strips andclean the area these are molds made of the same sheet that serve as a guide for the LED strips and these others are the ones that hold them to remove them we just lift a little and they go up the connectors.

.

they have brooches here you can see them .

.

and to be able to disconnect them you have to press both at the same time you can use the screwdriver or they can also do it manually to disconnect from the strip that isfixed on the foil it is done this way all the LED strips and theremove residues from the burned part with solvent I will only review the connectors of the fixed strip and proceed to install the New LEDS I already have the LED strips ready but .

.

I have to restore the sheets firstburned here we see it but .

.

I did not find onesame so i will try to restore it and I'll cut only the burned section this is the section to restore .

.

I will use one of another 32-inch television I will cut a section, I will trace the holes and then I will cut them with a razor that's it .

.

.

a bend is made so thatcouple with the other and ready now the acrylic.

as it is completely square without moldings can be cut I found another one of the same inches aslightly larger I will only trace the outline and then with a ruler and a razor I will proceed to scratch it and then with tweezers I just remove the leftover here are the LED strips and these metal tabs that hold the strips you can press a little bit .

.

.

straps are well fixed and the heat dissipates in the sheet I'm going to install a first strip this is the connector that goes to the strip that is fixed on the sheet and at the other end the connector that goes to the smallest LED strip the smallest LED strip only has this connector well.

.

connect it and insert it in the guides from top to bottom must be inserted well, until it fallsinstead and check that you make good contact I will proceed to do the same with the stripsmaller and with the rest of the LED strips on this last LED strip on the right side Below, there is a detail that I have detected in this model the support of the latter is further away than in the rest of the strips here you can see it .

.

.

and that makes it not fix well on the sheet what in turn will ithot envelope plus this latest LED so we will use a glue thatheat support .

.

here it is ready Another small detail is that the lenses ofnew LED strips have small edges just press the foilof the bottom in each one of them .

.

.

Very well, everyone is here and here you can see the graft we made, well coupled to the other Thats very good now we will place the pivots instead and we put the acrylic that was cut tomeasure now the other sheet.

.

this model only uses one I put the inner plastic frame .

.

and I can place the panel as always should be done with a lotwatch out It is done.

.

now we put the panel cards instead and the rest.

.

it's just about putting everything back together and testing ok let's try and we see that the lighting is uniform the restoration of the burned parts have been successful here we see that the user.

.

used the backlight to the maximum it only remains to recommend that you adjust thebacklight 60 to 80 percent well .

.

.

even if the LEDs are new thiswill help them work with less voltage and have more useful life ok folks that's it for this time if you have any questions about this video or if you require any additional information do not hesitate to contact me via facebook or email see you soon.
