I got a repair of SONY model KD-43X7500H, made in Malaysia, an Android smart LED Tv. The first time I worked on it, was that, it shows the logo SONY for a minute then the backlight turns off but still, you can see the panel's picture working as you can see it's silhoutte. I  managed to re-soldered the two ICs, which are 'square' type SMD ICs with I think, 10 pins on each sides (total of 40 pins) with label BD9424 0235 for each ICs. As I checked on it. there are two ICs to drive the LEDs in an in-line array arrangement), not the common types of backlights scattered all over at the back of the LED panel. I was successful then but just for a few weeks, the same trouble happened again. As I observed it, before the backlight turns off, there's a bit of a dimmer lighting at the right side of the panel screen. I resoldered it the second time and it worked. Now, the third time as a backjob, the panel screen will show the Sony and android letters logo with 'even' lighting behind the panel screen but then, after a few seconds, the backlight turns on with red light indicator blinking 6 times. I hope someone can show me the pin labels of the driver IC. BD9424 023, so I can study how to make some kind of modification, as I suspect, one of the ICs could possibly, already defective.In advance, thank you very much for those who could help. God bless us all.
