@oldturkey03 I have tried shining a flashlight in a darkroom in an angle where I could find the picture without backlight.. Thanks for the troubleshooting help. Could you please suggest me the fixing method and cost for the repair..

@navakumar that points to a bad backlight. You do want to go ahead and remove the back from your TV. Measure the voltages going from the power supply to the backlight LED’s (set your meter to ~250VDC). Let us know what that voltage is. It might also help if you post some good pictures of your boards and your interconnect wiring. That way we can see what you see iFixitでの質問に画像を追加する方法

@navakumar if I understand you correctly you could see the picture by doing the flashlight test. What make and model is your TV?

@oldturkey03 My TV model is 32pfl4479. I could see only black screen with audio.. but as you said when I tried showing flash light from downwards angle in a darkroom I could see the picture in a dimmed manner with no back light..
