Hi need help, so im buying the right thing.
My sons phone touch screen stopped working, and I've been told the motherboard needs replacing, not valid anymore with apple as we had back screen changed by others ��

Please can someone be kind and let me know what it is i need to find. I've looked and there is so many different bits, its completely lost me.

Thank you in advance

If it's the touchscreen i would say its the digitiser that's gone. You can get a screen with digitiser supplied and fitted for around 70 notes. I done my own recently and only paid ?30 for it on amazon.

I know the man who changed the screen, he did try a couple of different ones and it still didn't work, so its a digitiser i need to buy, thank you for your help

Sorry my son said i have it wrong it's the IC unit on the mother board as the fella had tested it and not to do with the screen? is there such a thing, or is that a digitiser.

Once again thank you

The screen and the digitiser would normally come pre glued together. If the guys tested a few and says its the motherboard then fair enough but it's very unusual.

Search for nimbus (U19) connections , and power suply .
Check c200 if there is 1.8v , r30 , r90...

And use google for these items... so you can get clearer picture what you have to check/change...
