Hello guys!
I am asking for help because I have an Bresser Biolux Touch 5mp microscope with an 4.3 inch tft that has no backlight.I have found that the boost ic that supposed to boost the 5v voltage for backlight is dead.The marking on the ic is : S87BaAA and is a SOT23 6 pin.I cannot find any result googling.I have replaced it with a generic boost converter and the device works,but backlight is always on,I need the datasheet of the original IC to find out how it works...I cannot find any schematics either.Maybe somebody has an idea...
Thanks!
