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.

Üdv Mesterek! Drót sorvégtranyóval érkezett, kicseréltem, de nem indult.Indításkor a sortáp megjön /terhelést is bírja/,majd néhány mperc után stby . TDA 8139-en 8v helyettcsak max.1, 5v kimenő feszt mértem rajta.TR60 tranyó fogta a 8V-ot, emitterét felemelve nem áll vissza stbyba , de a sorra nem megy. Sorkimenő új,TDA8855H cserélve, hiba maradt, hibakód nincs, stby led végig piros. Köszönöm a segítséget...

Sziasztok! A képernyő felső sarkában "gomb ---" felirat látható. Hogy lehet megszüntetni, a zár feloldása érdekelne. Kőszönöm!
