when i test my fpc on my 6sp without the lcd connected the reading is 0.2mv but when i disconnected the lcd the reading is 3.9 v? can you help me figure out if tristar is bad or not? thank you.
So I replaced a ic, charging port, battery digitizer display, but it is not showing any image on the screen and it is showing no amps or voltage, for the iPhone 5s, any advise to what it could be?
My iphone 6+ have been boot looping for months and I can't find the problem. software restore does nothing. Previously I have replaced the battery and charging port. Any idea of how to diagnose?
Only time I'd had this happen was because of the LCD. For some reason some LCDs work for short while but then put the phone stuck in a boot cycle. Putting a different LCD usually corrects this issue.
Could you please show more of these simple test techniques? How to identify other basic problems...
