Sony LCD backlight failure. Convert to LED backlight.

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.

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.

[@MikeleKonstantyFiedorowiczIV]

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.

[@martinlutherkingjr.5582]

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]

Its not causing poisoning until you break it.

[@martinlutherkingjr.5582]

@@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 KZbin will delete my comment then but if you google that quote it should come up.

[@angelosanagnostou5550]

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.

[@tevzTVTevatronics]

change the resitor at pin 3 to ground. example 1 ohm change it ti 2.2 ohms.

[@Artemiskun]

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]

certainly

[@premkxk]

Yes , ccfl produces so much heat and now the polariser sheet also protected for long time

[@stevec5000]

Tevz you sound like a robot! How did you determine the number of LEDs to use?

[@tevzTVTevatronics]

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.

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.

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.
