Hello, I recently bought a refurb screen off of eBay to fit. The phone was 100% working before and just needed a new display/battery.
The battery came before the display. I wanted to test the display before doing too much reassembly, so I plugged in the battery, connected the mother/daughter boards with the interconnect cable, and then plugged in the LCD.
When I press the power button there is the usual single buzz from booting, but the display is completely blank.
Is the replacement screen DOA, or are there important traces/connections made by fully assembling the midframe and missing screws before testing the LCD?
If I already have all the ingredients for a fair test of the LCD, then it seems the LCD is bad?
Like I said the phone worked perfectly before… and if the new battery is dead, I would expect no buzz, or at least a battery graphic?
