Hi @davemeran ,
Check what the voltages are on the power board and go on from there. Having no images on the screen whether there are backlights or not means the mainboard but if the power board isn’t supplying the correct voltages then it won’t work properly anyway.
There are several versions of your model using 2 different chassis so here’s a link to the [link|https://english.electronica-pt.com/electronica-search?find=42LB5610-TC|service manual] for the different models and chassis that they have.
I’ve checked both ''chassis'' models and they seem to have the same pinout/voltages for the power board.

-I think that the 12V is the voltage used to drive the inverter which supplies power to the backlights but not 100% sure on that, it may be the 24V
