Hello Bruce (Downunder) and SinclairTv , thank you very much for your comment and suggestions, they are helpful in attempting to resolve this issue.
The backlight went off again after 5 days, but, this time, STEP 1, I unplugged the Backlight cable from the power board and plugged it back again to see if it works, it didn't.
However, STEP 2, when I unplugged the same Backlight cable from the power board and then tried to power the backlight using an LED tester the backlight lit-up, after this I simply re-attached the backlight cable into the power board and to my surprise the backlight and TV started to work again.
Here, I am bit confused, I am not sure, if it is the backlight or power board itself which is faulty? Because, all I did in 2nd step was feed some electricity into the backlight through and LED-tester for few seconds and then it attached it back to the power board and the backlight worked, so, I am not sure, if somehow the backlight is failing or it is getting a signal after running for few hours to turn-off?
I would really appreciate your help! thank you.
