I injoy your videos. I have a 70 inch sharp tv model number LC 70LE660U. The tv turns on the back lights but won't turn them off. I have no picture just the blue screen from the back lights being on. I was wondering if you have ran across this problem.
Excellent work!! I hope you did not take my comment on the other video about using more flux, as bad. I meant no insult saying that, I was just trying to help improve solder flow and solder joint stability.
Hi Tevz, I like to use a 60W incandescent light bulb in series with the mains power to prevent fireworks. I actually have 3 bulbs which I switch on with individual switches to increase or decrease the line resistance. I can send you a photo of it if you are interested..
Hi friend.would you tell what is the watt of the large 120 ohm resistor that you use for to be sure there is a short component or not? And the second question is how do you know which ic belongs to which part of tv? Please guide me to learn it. Thanks a lot.
The main reason there is no output of the LED driver is VCC 16 volt in the PWM which is present, and the mosfet is ok, so I decided to first replace the PWM.
master Tevs hindi ba puputok agad ang pesa pag series resistor lang ng 220 ohm hindi ko pa kasi na try ! series bulb lang kasi gamit ko lagi paghindi ako sure
i ask sir what is the problem in the screen when watching t.v theirs a box blinking with red letters down the lefh side of the screen what is the wrong of this hope you make a video about this kind of trouble thank you. thd
Your show is very professional and your English is clear thank you

No display and can't turn it off. Seems it's a different issue. looks like the pane is the problem.
@@tevzTVTevatronics I enjoyed your videos. Have you ever repaired a main board for the shape 70 inch tv
check the panel.
Best work.
Nice one
Thanks 🔥

even no flux will do.

incandescent light bulb is ok. Also resistor is ok.
@@tevzTVTevatronics incandescent light bulb looks better instead of the resistor, because if you got the short circuit - you can see this. :)
Send me too
Thank you for sharing your knowledge 🥰
You are so welcome
Nice work. Thank you.

Hi friend.would you tell what is the watt of the large 120 ohm resistor that you use for to be sure there is a short component or not?
And the second question is how do you know which ic belongs to which part of tv?
Please guide me to learn it.
Thanks a lot.
It's 220 ohms 20 watts. you can google the part number, or see the circuit diagram if they are similar.
Fun to see but no info on how to solve problem on other TV...
nice explanation ,but how do you know pwm driver ic is faulty .please explain this
The main reason there is no output of the LED driver is VCC 16 volt in the PWM which is present, and the mosfet is ok, so I decided to first replace the PWM.
Thank you very much
Happy new year 20223
tevz how much do you think is that PWMIC and where i can buy it?
Bel lavoro
Thankyou!
At 4:32min how you judge that mos is ok & pwm ic are defect please
Mosfet 's are usually shorted only if is damaged Pwm ic and the mosfet is the only main ingredient of the LEd driver.
💕👍❤️
How use multimeter digital kin use
good afternoon sir please explain Sony led tv 32R 512C stand by led 5 time blinking
👏👌🙏

master Tevs hindi ba puputok agad ang pesa pag series resistor lang ng 220 ohm hindi ko pa kasi na try ! series bulb lang kasi gamit ko lagi paghindi ako sure
