Hi [USER="169795"]lotas[/USER] , thanks for the reply!
So if I change the software version or check for screen size on the service menu the backlight driver will change its values to push up from 68V to 150V ? No need to change anything by hardware ?lotasHi [USER="169795"]lotas[/USER] , thanks for the reply!

2 pictures are from my faulty board (65" led TV), and other picture is from the replacement board !
Has it reads on it's label (150-165V) on 65" faulty board. And it reads (87-99V) replacement 43-50" board.
I have been searching and one some they say that if the resolution is the same and part number and components structure is the same it will work!
But on others they mention the eventually of a different DC to DC structure!
The only difference I can spot by the picture is the on the inverter side of the board my bigger TV (150v...Last edited by Cvrado; 03-02-2024, 05:19 PM.Leave a comment:

Even the components are all identical and the structure and design are the same .
I only find a MOSFET that o presume it is a Jumper Junction Power MOSFET . Is the MOSFET responsible for a push up voltage? Or will the board manage for itself the necessary voltage to the backlight has the moment it is connected ?

Led TV Board Replacement, same part number and model, different size
Hello my friends!
I have a question that I think you can answer and help me with!
I have a faulty main board from an led TV. And I found the same part number board and design but is from a 43" TV and I want to use it on a 65". On its stickers , all are the same except the wattage for the LEDs backlight, both state different watts and LED Voltages!
So I presume that the backlight inverter section from the replacement board has lower wattage then the original one, am I right?
My concern is that the board won't draw enough voltage to the bac...
