Re: 820-02020 No backlight 0,8v on BKLT_EN_R

Back at it again! Was on a holiday. Got my small LCD cable but still no luck. Now im thinking this was the problem all along... But while I was looking somewhere else I destroyed something!

The enable signal (BL_PWR_EN) comes directly from u8100, does that mean that u8100 is failing? It produces 0.8v but not enough to logic high (1.2v-1.8v)?

I noticed that RP842 pin 1 has a diode mode reading 0.019 and 0v which was 0.187 and 0.8v. But should have been 0.375.

When I remove RP842 I can see diode mode reading of pin 2 is 0.575 and pin 1 is 0.019! im really out of ideas now!
