Have you tried replacing the lcd?


cnbrkclk the lue light on your panel sounds like the backlight. Why did you replace all of them? Beside replacing all those boards, what else have you tried? what model is your TV? Post some images of how you put it all back together. Use this guide for that.


I've never seen and lcd replacement be cheaper then buying a new tv.


@willfixforfood definitely not on a 70" panel ;-)


Well replaced all becouse I want to try all :) I m not that professional electronic fixer :) and easier way for me to replace them with new parts so.. now for sure my all boards r working now .. only I never check the light strips but when I look them behind the frame I can see there is white lights coming.. I will share more detail with picture with you guys and give more information tonight .. iam at work now so .. but thanks for atantion
