I have ended up with no backlight after changing my digitizer on my iPad mini A1489. I read that many say it can be fix by soldering the fuse, but my iPads circuitry seems a bit different from all of the other posts on the subject. Can anyone point me to the fuse that needs to be soldered? Does anyone offer a service so repair this correctly for me? Any help is greatly appreciated!
Questa è una buona domanda?

dont ever understand how people do this.
ALWAYS turn off and disconnect power when doing repairs.
You most likely burnt out the backlight filter

I did disconnect the battery before disconnecting anything else. That's why this is so frustrating for me. I've been fixing iPads/iPhones for years...

Hard reset your iPad mini by pressing power and home button for 7 seconds. Supposed lost backlight comes back. If it didn't help, then we will find a solution for you ahead.
Take a multimeter and check out if any of these chips are inactive. Black needle of the multimeter must be at ground. This should help you replace the bad one.
Or watch this video and follow carefully. One mistake will damage the entire board and make it useless. https://www.youtube.com/watch?v=8je_i_za...

I have tried the hard reset several times. I also tried leaving the battery unhooked for more than 120 seconds. Still no luck.
My iPad logic board does not look the same as that one, how can I upload a picture to show you what I'm working with?
