@kbala2017 okay we need to know what model your TV is and what was repaired. If it is your backlight that is out then it is most likely your power board. If it is vertical lines than it could be your T-con board. Post some pictures of what your screen shows with your question. Use this guide for that.

@kbala2017 looks like your bottom LED backlight strip is not fully lit. Could be an issue with the backlight strip. You also may need to check the voltage from the power board to the strips and see if it is consistent. For now I would leave it and wait. Or at least start checking it and try to get the right parts first. What model Onida is your TV?

Leo 50 fc I already repair it but I am worried it will be happened again. What solutions to prevention it or exchange my led tv. Or how many years it will be work once backlight repair done

@kbala2017 nobody can predict this. A good repair can last a very long time. I would suggest not to worry about it and just enjoy watching your TV:-)
