Hi Tevz, In many places this TV would have been scrapped. Thanks to your skill it will probably work for many years. You saved the owner a lot of $$$$! Well done.
Tavern
this is absolutely amazing work. am from Nigeria keep the good work dear tev technology.
Very impressive work this was really interesting.thank you. I am thinking about a conversion like this
Glad you liked it
Great repair, not seen that done before. Bravo my friend 👏👍🏴👏👍🏴
Very nice Job Sir! Thank you.
Thanks you tevz for your videos.
You are a genius!
that's great work ! thank you for that info Sir ! , ive learned something new today . keep up the good work Sir !😃
Watching again master
espectacular trabajo, saludos amigo.
Excellent video
Very nicely done.
Grande tecnico💯👍🏻
خیلی عالی خسته نباشی
Nice sharing sir
Hmmmmm yes I know there a way to convert the lcd back to led.
But didn't know how to make the module drive. Thanks Tevz.
For this. ❤️👍
No problem 👍
Have you got the circuit to build driver supply for led backlight
Very very good👍
thank you so for good tutorial sir..
You are most welcome
nice idea , very useful tq boss
Welcome
Great job! :)
wow ...very nice sir
Keep watching
Hi Tevz, on your led driver circuit, is there a way you can reduce the current since at 300mA the LED's run hot and they might not last long. I like to drive them at 220mA.
change the resitor at pin 3 to ground. example 1 ohm change it ti 2.2 ohms.
Tnq bro gud
I have a similar model TV and am also considering a possible conversion like this. I was wondering, have you noticed if the heat produced by the converted TV has decreased by much?
certainly
Yes , ccfl produces so much heat and now the polariser sheet also protected for long time
brilliant
Me too .and learning. 😊🤗😃👍
Great 👍
Thanks for information sir
Welcome
U r good ticher
...молодець )))
Thanks ....
My set seems identical is there a link to the inverter driver you made? Thank you

hebat master....ngk jual driver buat bakligh nya ya
Nice
Preciso do link de como fazer este conversor para leds?
Hi Tevz can you confirm the fault originally was set switching off after about 5 seconds like mine. Any thoughts about tgat inverter on ebay to purchase. please advise
Disable the BL error by connecting it to the ground.
@@tevzTVTevatronics Hi Tevz i have disabled 1st 2 pins connected to the inverter board and although it stops the blinks the lamps still turn off. Also disabling pin 3 is the BL error does the same. If i don't disable those pins the lamps go off and come on then off again. I keep checking the power supply but really not sure😑
@@walker55able Keep trying. Try also the BL error instead of connecting to the ground. Connect it to 5 volts.
Thanks,
Welcome
Very interesting Video Thank You.
I want to know what type of LED's you have fitted. what is their identification number. What are their voltage and current ratings? Where do you get them what brand are they. I assume they must produce a pure white output.
The LED is a concave lens, I fitted 15 pieces 3v equal to 45 volts. The ampere is about 300 milliamps. You can buy it online. Concave lens 3 volts factory cut LED pure white.
Just didn't understand how did you bypass the inverter protecion. Can you explain?
short the LB error to ground.
Peace, mercy and blessings of God be upon you, my respected professor. Is it possible to convert a plasma screen from a QDSM type to an LED screen, and if I installed LEDs and the coachboard, or is it not possible?
Plasma tv has no Back light. It is not possible
interesting. How do you control the brightness?
no brightness control.
@@tevzTVTevatronics Is there some way to add this feature and to be able to adjust the brightness at least by the screwdriver from the outside? Great work BTW 👏
Hi Tevz can you tell me please where o can commande these leds ,Best regards lee
LED driver
for how long the LED will last (hot LED)
👌
Hola Amigo, tus vídeos son fantásticos informativos y precisos, pero no comprendo bien el ingles y este vídeo no tiene subtitulos. puedes hacer un video en donde hagas un cambio de lamparas ccfl a led en un TV LCD, ya que las lamparas no se consiguen y el consumo leds es bastante inferior. gracias por leerme un abrazo Amigo.
Don’t those CCFLs have potentially mercury coated on them (not just gas)? Meaning dangerous to touch? Any symptoms of mercury poisoning since this video?
Its not causing poisoning until you break it.
@@tevzTVTevatronics “The literature reviews showed that not only does the fluorescent powder in CCFLs in LCD TVs contain mercury; in fact the entire CCFL, especially older and used CCFLs, have mercury amalgamated to the glass and the electrodes as well”
There was a study on this I cannot post links because CZcams will delete my comment then but if you google that quote it should come up.
hi sir
i want to convert a philips lcd tv to led like you 37 iopinion nches particularly how many leds must i use in your opinion
how can i avoid the bright spots from the leds ?
i ask because older i has convert a philips lcd tv and looks the leds like bright spots
can you tell me the link wich you buy your leds ?
28 is enough, 7 led in 4 raws. Use a concave lens type to avoid bright spots. www.lazada.com.ph/products/1003v-concave-lens-universal-lcd-tv-retrofit-led-lamp-beads-32-65-inch-backlight-lamp-strip-particles-i2752484170-s13217695674.html?exlaz=d_1:mm_150050845_51350205_2010350205::12:16442886951!!!!!c!!13217695674!545894062&gclid=Cj0KCQjwio6XBhCMARIsAC0u9aGG1apl6cKpoyS3MwOjASmXJteRjSY5xa7rHEmQH3W4abzP6dIUqX4aAjfdEALw_wcB

a similar product from aliexpress for example ?

Sir san ka sa ilocos ?ippaayos ko sana Yun tv ko
I cannot thank you enough as I have followed your video carefully to reveal my LCD lamps ( my set is identical to yours). I have black marks sadly on the lamps. Can i clean them with sandpaper? I guess not but any advice would be great.☺
You should replace all insulators
@@tevzTVTevatronics Thanks. I notice the one
One lamp glows an orange colour which i guess is the issue. I just need a replacement Lamp which is easier said than done!
@@walker55able They break easily.
Hola maestro, no era más conveniente instalar los led y toda la conexión por debajo de la lamina blanca? Por estética y además para mayor disipación de calor de los led en contacto con la carcaza de chapa? Saludos!!!
Tevz you sound like a robot! How did you determine the number of LEDs to use?
I use a windows narrator so the voice sounds like a robot. I use 3 volts LED in series in this video equal to 45 volts, The inverter that I use is a constant current sensing. The voltage out is 18 volts to 120 volts 300mA. It can drive up to 40 LED in series.
Good boy
Muito bom, só não sei como fazer o indutor???????

Thank you. That was a surgery.
Hello, I have a 46" Sony television, how do I calculate how many LEDs I am going to put in and what type I should put in each row and how many rows it should have, and what driver I should put in it. I am from Venezuela and your answer is important.
40 pcs, 3 0r 6 volts, use concave lens for better results,.
ok 40 LED how is it distributed and at what distances between LEDs and what distance do I put from rows to rows, can I use the same driver that you put since for 40 3 volt LEDs it gives me a voltage of 120 volts what do I do in that case greetings from Venezuela following all his videos, techniques and teachings
Hey sir . I follow way of u, it good, led bright nomal, when one of leds broken, voltage down.....
When i add A 1015 into circuit, have big problem when led broken. Voltage very high. No down. Near 400V Please check again. Thanks sir
How to. Buy the converter 😊

Can you give me the LED driver diagram?
Hi again Tevz would you be able to sell me one of those made up inverter kits at all as I feel a convetsion like yours here is what is needed and i am struggling to find replacement tubes. Thank you
There are tons of inverters sold online.
@@tevzTVTevatronics Hi Tevz thanks I am particilar intetested in your backlight inverter as my set is almost if not identical and would be happy to purchase the kit from you. Hope that's okay.Thank you
@@walker55able where you from?
@@tevzTVTevatronics i am in the UK Tevz North Cumbria England0
@@walker55able Ok. about the inverter is not that I don't like to sell it to you but the how I can send it to your location.
Use ready-made backlights driver and led stripes for saving time and money
Sir using in transistor a1015 canection?
Sir ano po yung bl on na wire nya?
may naka sulat sa board
Sir please help me i changed like this but after white spot is coming
Use concave lens
Greetings, excellent video, I am interested in the diagram, could you pass it on to me?

Mayroon akong screen ng sony bravia para palitan ang mga ccfl asia led lamp. Ngunit kapag inilagay ko ang video, naka-off ang screen at ang power bulb na lang ang nananatiling naka-on
Disable mo yung bl protection. Nakikita yan sa mga wire pa punta sa dati niyang inveter, i connect mo yung bl protect sa ground.
you should have shown the brightness control
The tv is using PWM to adjust the brightness of the CCFL inverter. STRW6053 doesn't have a PWM function to adjust the voltage output level. So there is no brightness or adjust of the LED level.
Do you need LCD TV backlight belt?Our manufacturer can provide you with a large number of products.
How to avail?
Led strips must be on metal surface because they transfer heating
yes its true

Protect parin master
ano yung nag proprotect?
دوستا یادتون باشه در صورت گرما مداوم و شکنندگی پایه پلاستیکی نگهدارنده لامپ های فلورسنت،سعی کنید پایه های هر ردیف رو چپ و راست بیرون بیارید که در صورت شکستن خارها حداقل یه پایه چپ و یه پایه راست برای نگهداشتن لامپ های جدید باقی بمونه...😊
Paano po ginawa mo master para hindi mag protect? Diba po maselan ang sony?
Naka disabled na yung lamp fault.
@@tevzTVTevatronics newbie lang po kasi ako master, san banda po?
Sa main board po ba o sa power supply board master? Thanks po
