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.
This is really good 👍 Nice Fix . Ive just aquired a 46 inch 1080p samsung tv for free, with the same backlight problem and thought, Can i just put leds in there ? 🤔 . . And found this video 👍
Good morning. Your interest in TV modification and make it work is very very Good to see. In this regard can I get suggestions and repairing tech solutions from your end. Regards Jebaraj.
Hi Tevz! I have sony 52" with ccfl backlight but it's not working now & I like to replace it with led. I watched your video, but my problem is my tv has two high voltage board and inverter both side. Can I use only one high voltage board & one inverter? I hope you can give an answer. Thank you so much.
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!!!
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
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?
@@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 TH-cam will delete my comment then but if you google that quote it should come up.
I got some commercial lg tv, shit take about 300w, its to much, but it got old CCFL, do you think converting to led give a lot smaller energy consumption? And what about brightness, orginal has about 500nits, but for me 350-400is enough.
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.
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?
@@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 👏
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.☺

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.
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.
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.
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?

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
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.

I have a sony klv-40bx400 flashing stanby light 6 times can i start the set with the inverter plugged out
this is absolutely amazing work. am from Nigeria keep the good work dear tev technology.
Yesterday my friend gave me this TV for free. It's amazing!! Better than my Samsung from 2018
Alot of the high end 1080p tvs from 2007 - 2010 are still Way better quality pictures than most Much newer LED tvs 👍
Very impressive work this was really interesting.thank you. I am thinking about a conversion like this
Glad you liked it
Keep it up master. You're great in modifications
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.

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.
