Have a 40inch Soniq which is displaying an image with half the screen slightly darker (or maybe the other half is slightly lighter) an example of this is shown in the images. These units have a power supply, mainboard and an integrated tcon on the panel tab board.
Where I live these units were a very popular sale item and there are still loads of them around. I've now recently seen two of these with this fault (more to come). Instead of just binning it, I'd like to get to the bottom of what is happening.
It's something on the integrated TCON or the panel as swapping out the power supply and mainboard make no difference. Both sides show a perfect image, just slightly different shade. This particular model suffered greatly from failed LM1117 regulators on the mainboard.
Any clues or hints considered gratefully. I'd like to think it's a bad cap on the tcon, but hey, cannot all be lucky.
