Well, it is the question of the million, as you know it has no audio if you do not have an image, put it in hdmi and you plug the antenna ... the test is with the oscilloscope measure if lvds signals, in the video you indicate the analysis, some screens if you disconnect the clock lvds make patterns of colors, you know what the clock, in the datasheet of the panel is indicated as pin 21 and 22 of the connector lvds, main or panel, hen or the egg ... with an oscilloscope you can know what does not go
may be the firmware ...

I ran out of characters, hahaha
in short, with a main from another tele or with an oscilloscope you can diagnose or with a tip to measure lvds, but these are complicated to diagnose the problem
