New LCD Controller Board for Tv
Is the backlight powered?
Yes it is. I can see white lights coming out from the back of the display.
At this point it’s really hard to troubleshoot from the distance.
Of course it’s possible that either the board or the panel is broken. I suppose the menu isn’t displaying either?
Have you made sure you loaded the correct firmware onto the board? You should be able to try any firmware which fits your resolution plus 1-ch 8-bit (iirc, check yourself please).
