So just to get thing strait, you still did not solder pico to this?
You only solderd the wires and flex and while the shield is off it boots to OFW when the shield is on then it's black screen?
Asuming the above is correct then:
- The flex on point 1 could be scratched and make contact with shield once closed.
- The shield might be putting pressure on the solder joints in caps (point 2) even though they are covered with capton. This might cause a crack in joint.
Retouch those points and try to have visible gaps when finished (as in photo)
Hey QuiTim thanks for the tip, i resolder and clean the flex, turns out the short came from point 2 of the flex cable wrong soldering point after comparing with video sx core installation.
at last its alive after 5 hours of shady first timer micro soldering lol, this photos taken before putting solder mask
quick tips for beginners or first timer like me:
*right tools for the job is important, especially microscope if you can effort to risk $200 switch tablet, why not invest in $100 microscope instead, you wont regret it.
*read all the threads, find other people comments and installation photos to make sure you know what to do, compare it with the definitive guide, also installation video of hwfly sxcore would help your understanding of the whole picture better before doing it yourself.
*buy SMD training kit or other dead micro electronic board for solder practice, i use my dead RCM dongle + smd training kit for this.
* flux and IPA 99% are your bestfriend always use before and after soldering, making it your reflex
*also you can use single wire 36 AWG for all installation, i use one from stethix.
next will try full mosfet v1 install before moving on to oled ( mosfet is super hard for me i gave up first time, i do recommend use flex v1 or v2 instead) THANK YOU guys ...
