Iphone 6 no video after touch ic repair
 

Hi. I have iphone 6 with touch problems.
Reballed touch ic and then no video, backlight working, phone turns on and connects to iTunes , rings and all.
Reballed touch ic again, replaced it and still same.
I have checked all filters, reflow video ic but no luck.
Can anyone point me on the right direction?

Thanks

Touch IC shouldn't cause no display, try booting with Touch IC off the board.

or you floated chestnut on the other side

Replaced chestnut. Still same.

If it was working prior to reballing the Touch IC you definitely messed something up by using too much heat or your reball was bad, the new Touch IC could be bad also, check for shorts around, and like I said try with the Touch IC off the board, there are display traces/nets going through the Touch IC, the chip is not needed for display however if it's shorted it may cause display issue.

Working fine with touch ic out. Just no touch... will try another ic then

If the display works when you remove the mason ic that mean the traces not connected correctly or melt some traces together OR wrong orientation OR bad IC
