As long as you're getting full backlight but no image check chestnut ic. This provide voltages to touch and display. It is most likely not gpu related. I would still inspect coil for cracks/damage as it might not be putting enough voltage through to give full backlight to image. If you tilt the board and look under chestnut (u1501) you might be able to see under ic for cracked solder balls. I normally don't recommend reflowing but you could put some flux on the ic and heat for about 20 seconds at 355 if balls underneath look cracked. Also check voltages out from u1501.
Saiba maisRemember the separate home connector cable on the 6 and 6 plus you could replace apart from the screen? This ran from the connector on the board, underneath the metal plate and to the home button flex itself. I'm assuming this is just that. Simply connects your home flex to the board itself.
Saiba maisGuaranteed your battery is dead. As soon as you swap the new one in it should fix this.
Saiba maisI would first inspect the physical digitizer connector (long one above lcd and front camera connector) and make sure all the pins look good. If they do it might be a touch ic problem. Standing lines w/ no touch or intermittent touch is classic for touch ic problems.
Saiba maisHey, gotcha. That's actually very common with the iPad mini digitizer replacement. So that would actually have nothing to do w/ the lcd. If its ever a problem w/ touch on your device it will be related to digitizer and any problems related to picture is lcd. Most likely one of two things is going on. Either your replacement screen is faulty or your replacement screen didn't come with the protective cloth tape strip at the bottom. If you still have the original screen and look at the bottom inside of it, near the home button hole, you should see a thin black cloth like strip that goes along the width of the glass itself. This helps against what's called "ghosting" which is what you're experiencing. Its kind of weird to explain so hopefully that makes sense. If not or if you have any other questions don't hesitate to ask
Saiba maisI would definitely have a professional look at repairing the charging port on this model. Saying this is a difficult task is an understatement even for professional micro solderers. The charging port is soldered with high melt alloy to the board itself. Basically this is a $@$* repair usually not worth doing.
Saiba maisAl,out always when wifi is greyed out your wifi module on the back is either damaged or a surrounding cap needs replacing. There wasn't heat applied to that area if the board was there?
Saiba maisI was going to upload a video walking through what to test but ifixit is retarded when it comes to uploading media. I would recommend taking the new ic you installed off and powering the device on with no new cumulus broadcom chip installed. It should power on without the chip. This will let you know if the chip was installed correctly or if you accidentally bridged pads.
Saiba maisHi, first I strongly, and can't say enough STRONGLY, advise you don't continue to attempt to turn the device on. I would take it to a reputable repair store and have them run a professional cleaning on it. Make sure they use an ultrasonic cleaner and remove any necessary shielding over board components. You basically want to clean off any left over minerals from the liquid that has been left on the board. Many times a cleaning itself will work but in the case it doesn't and you have one or multiple shorts you will need a board level specialist to look at it. Also I wouldn't wait as there could still be liquid sitting in the device waiting to cause more damage. If personal data is your biggest concern be very picky who you let touch your phone. Just because they operate a store doesn't mean they're good at what they do. I'd check out the business's online reviews prior to letting them touch the device. Hope this helps a little.
Saiba maisHi, first I believe you have just an original iPhone 6 plus and not the 6s plus. Reason I believe this is the iPhone 6s plus almost never has this issue, while the original 6 plus is notorious for it. If you look at the back of the iPhone and see an "s" right above designed by Apple in California then you have a 6s plus. If you don't have this standalone S then you just have the original iPhone 6 plus. Aside from that you're correct on your research. This sounds 100% like a classic touch controller ic problem. What happens with the iPhone 6 plus is overtime the phone bends and puts stress on the motherboard itself. This puts stress on the connection from your controller ic to the board (connection is in the form of solder balls). Occasionally the chip can fail but more often than not its stress on the connection that. Correctly fixing this would require removal of at least the meson ic (this is the larger one and usually causes the problem) and replacing it with a new one while touching up the connections....

Board level repair. General repair is too boring.
