How to adjust the backlight of LCD?

Post by Carmelita »

I have a TFT LCD, but I think the brightness is not high enough, so I want to adjust the brightness myself.

If you alter the control, is there any change in brightness ? Is the control enabled ?

Is it lower than when it was new? Are you hunting a failure or do you just want it to be brighter. If it has n OSD, that means it is a digitally controlled DC to DC converter somewhere and without a schematic, modifying it may not be practical. If there is a failure making it too dim, then maybe you can find the bad component or maybe its the actual backlight lamp. Is the backlight the smaller flex cable at the bottom?

Can you point us to the right links
