Electronic enthusiasts now use TFT LCD screen to transform a lot of small color TV, I also dozens of restructuring, now introduce some of the tips to electronic enthusiasts.

Sharp 5-inch is the same, the difference is the first 13th cable is not connected with the LCD drive cable seat, a separate ground can be. At first, found that the restructuring of small color TV shows very dark, how to debug will not work,
