From CCFL to Led on Sony Vaio VGN N MBX 160 Foxconn MS70

Regards. I bought a batch of 10 15.4-inch CCFL lamps for Laptop last December in a Chinese online store (it took 40 days to arrive), but it turns out they had an error and sent me 2 Upgrade Kits to Led, they assumed it and they go to resend the original order, now I would like to try to install it but I make a mess with the cables, the laptop is an old Sony Vaio that I already have it tuned and performs well enough to be a team with more than 11 years (until it plays videos of YouTube in HD), here the specifications , the screen has only one lamp that is currently in its last days , as we see here . Is it possible to do it or is it better to wait for the lamps? If possible, could someone please help me with the correct installation of the cables, attached images of the kit and the connection on the Board and the Inverter. Image 1 Image 2 Image 3 Image 4 Image 5 Images of the lamp on and connections: Image 1 Image 2 Image 3 Result here. Many thanks to mac2esperando and his valuable collaboration.

Thanks Salvador for the answer, yes, it is really a mess to do that conversion with the adapter that comes with the Kit, most likely it will damage the computer, someone on that site suggests finding an inverter for LED that is compatible and that is what I'll try, if not, I'll wait for the lamps.
Although if there is someone who suggests something else I will be attentive.

Yes, you see 2 kits and your system only needs 1. The small plates that make inverter have cerigraphy the voltage, with a tester it measures if the voltages that the mother delivers are the ones that says there and in that order. If they are the same you shouldn't have a problem.

Thanks jochu73 for the answer, here: https://www.youtube.com/watch?v=nv_uQhyeBO0 someone tried it with the same Kit and ruined the laptop, now I'm focusing on getting a compatible inverter for led, I know that the laptop is practically obsolete but I give it a sentimental value and it still works very well.

Well, it is seen that he used the original power cord when one was supplied to replace it. So it is not known if I made a wrong connection or was not compatible. Better wait for the CCFL kit to arrive. I would have chosen to look for used parts in premises that are dedicated to laptop parts.

4-color connector has 1 and 2 inverter power, 3 enable and 4 brightness adjustment (PWM). from the other side to the lamps. The 6 conductors that you have on the board is because 5 and 6 are GND here it is not necessary to use the conductor 4. So the only thing you have to do is to anchor the plug of the four-color cable in connector 2 of the 6-connector jack From the board there you have already fed the LED inverter and now to connect the LED strip. Hard? Here you see why carelessness causes failures: This is on the motherboard so you must connect the plug of the Chinese inverter on pin 2 so you have on the next 3 the enable or enable signal and on pin 3 the brightness signal and by pin 4 gnd ground. The failure you comment was to match the chips and you would be sending the PWM modulation by pulse width to mass creating a short. The 19N10 is a mosfet N of 100volts for the configuration of the strip you need to raise from 9 -> 20volts to approximately 60 volts to turn them on I think it would work. The mistake was in keeping the original cable the kit is for full use, do not forget that it is an update. It is your decision we have cleared the doubt. Jochu I see that you are very good live greetings. This is the connection: https://www.youtube.com/watch?time_continue=3&v=c1Qr-VLeCCw

Thanks mac22waiting, the plug of the kit is bigger than the laptop, impossible to connect, would touch solder, I leave you an image with what I thought you understand, please can you explain what color goes with which color, I would lose control of brightness but it doesn't really matter.

No Sebastían, look at the mother's 6-pin socket as I am seeing it in your picture, do you see the "1" and the "6" in the silkscreen of the ends of the socket?

Responder

You have a strip of four wires that have been sent to you, yes?

Responder

Well the red cable receives from the mother the power that can vary but is close to the input of volts that your laptop has if they are 19 because that is 12 because it is in battery because that.

Then you see that there is no cable because the LEDs require less current therefore you skip a place and you see in position three the yellow cable that is the enablement

Responder

then follow the white wire in position 4 there you have the brightness (PWM) and then follow a blank space without cable but in sixth position you have the GND mass and it is perfect.

Now I ask you, don't you plug that cable into the mother's connector?

Thank you very much mac22 waiting, now if I understand it thanks to your diagram, it shows that I am not technical, I just 'cacharreo', with respect to the connector of the Led kit is larger and the wires are also thicker, I would have to weld them to the 'wire rods' 'that reach the inverter of the' laptop 'or try to pass the wires of the Kit to the' plug 'of Vaio. I have another question: 32V 1.6A is printed on the inverter and on the adapter of the Kit it says 9-25V, wouldn't it be a problem?
Tomorrow I do the 'operation' to see how it turns out, I will be commenting.

9-25volts is the operating range if you connect with the charger you will have 19.5volts constant but if you leave only the battery then from 15, 13, 12, up to 9 volts you can use the inverter circuit then immediately turn off due to lack of battery charge. While 32volts at 1.6 amp is what it provides, less power consumption than the ccll and certainly much longer, as the 60 LEDs are located on a thin strip, they are grouped into approximately five groups of twelve LEDs each group so that a 32volts output source can feed all the LEDs of one, each led should shine

Responder

with approximately 3 volts and the five groups should consume a maximum of 1.6 amps. Taking into account what the ccfl consumes, this conversion represents an economical solution.

Hi mac22 waiting, I am trying to make the connection with the kit cables on the board and the truth is impossible, the pins are very large for the original cable connector, if I use the original cables is it possible to do damage ?, because I think that the connection of the original cables in the small connector of the kit if possible, I attach a couple of photos.

You might want to keep the original cables that go to the original inverter ... no.
Maybe you are reversing the ends of the kit's new whip?

Responder

The only way I see him is with the original cables, but yes, following the instructions you gave me with the correct order of the cables. Could it hurt if I use those cables, even if they are in the correct configuration?

Responder

To avoid any damage you should clean the contacts of the original cable to leave only four conductors respecting colors to not match you.

Finally I had to use the kit cables, the original cable pins that go in the inverter are tiny and do not fit the kit, fortunately the pins of the small connector of the kit if they were attached to the original connector that is on the board, but Then at the other end the big ones followed, the best and only solution was to cut the wires of the 2 kits and then splice the ends, I leave you photos above the lit lamp and the connections, Now follow the assembly of the LEDs on the screen , when everything is ready I upload photos. Thank you very much mac22 waiting.

Those insulated joints with heat shrinkable spagetti otherwise you will sooner or later have a problem and tefelicito Mr. for the adaptation you made you will have somewhat less consumption for which the battery is grateful. A hug and I wait for the final photo!

It is very complicated to mount those LEDs on the screen but that's it, it was perfect, I had thought that the brightness control was lost but there it continues, only now it is inverse, when it increases low, and vice versa, oh and when it is only with the battery and the brightness varies (only when the brightness varies) the LEDs flash a little. I will assemble the laptop and in a while or tomorrow I upload a photo of the result, it seems new.
I want to thank you again for all the information you gave me, it is very pleasant to find people as kind as you, many, but thank you very much.

Toti, how are you? One question, could you solve the investment issue on the screen brightness control? I say this because I just passed an LCD screen from CCFL to LED and exactly the same thing happens to me. It is certainly not something to die, but I would like to leave it original. The truth is that the change from CCFL to LED is brutal !!!

Hi Avila2474, I never really looked for a solution and I think he does not have it, it is only getting used to it, if there is someone who can help you in this, it is mac waiting, he is very kind, and yes, the change is tremendous, my laptop seems new.
