Hello,
Currently trying to repair a water damaged temperature "camera". Come a bit on the way.
It have a small color TFT with LED backlight, the anode-pin on the ribbon cable had been damaged, and probably might have shorted to the cathode.
The TFT is working great when feeding the LEDs from a separate supply
The LEDs are in series, 4x white. However i only get 3.3v to that pin and that wont do :)
When tracing backwards i come to this IC, that i am hoping to be some kind of step-up for this application.
However, of course it might be some other short that may trick me and my multi meter. When trying to search for the IC-name i don't have any luck.
Is there someone that might know what IC this is?
Thanks!
