Touch Screen not working properly- replaced cracked screen

I managed to replace the broken screen on my iphone but now 7 8 9 are not working. I imagine its the ribbon number 3 not in correctly cos this was a bit tricky but when I try to lift it up with the suction cup the screen only lifts up cos of the sticky tape!

I've tried a bit a blue tack inbetween, failed.

Another reason could be was it damaged during repair from heat off the hairdryer?

Any tips on what to do next please?

I pullled it out using an exacto knife, tried ribbon 3 and still 7 8 9 not working. When I press 8 number 5 responds. I can't get past my passcode!

Any help please?

Thank you

Lisa, it has been my experience that if part of the touch screen does not work, it is the digitizer that is failing. I would contact the vendor and see if they will exchange the digitizer. Of course, always check and double check your work as well as the connection, but ultimately it looks like the internal grid of your digitizer is not accepting the touch. I suggest to replace it. Good luck.

Thank you for your reply. I have double checked my work and can now see that the metal piece that the lcd slides under is not flush with the connecter, I have informed the vendor and hope for a new unit. I'll let you know the results.

Do you know anything about the number 2 ribbon. Did I need to replace the sticker, does it act as an insulator? I'm unsure of this.

Many thanks again

Lisa

Lisa, you will be okay without the sticker.

Lisa, also the #3 connector/ribbon doesnt have much to do with the touchscreen. Unless the ribbon is faulty, or the connector is damaged, the only thing you'd notice is "ghosting" or an ultrasensitive touchscreen. Like oldturkey stated, you more than likely have a defective unit.

Be careful with the #3 ribbon as well. If you notice the speaker or proximity sensor not working after all the manipulating, then you may have to change it out. I have a diy on here if you need it. Report back once you have results!

if you are repairing a 3g or 3gs the digitizers are different and the screen will appear to work backward. Check to see if you have the correct replacement part.

I'm having a similar snag - replaced my digitiser glass and I noticed a poorly performing touchscreen. Managed to open a drawing app and noticed that about 4 horizontal lines could be drawn and only between two of these lines could I draw vertical and diagonal lines.

Can anybody confirm whether this could happen due to faulty connections or would it be a faulty replacement digitiser?

you guys are buying those cheep ebay screens from china for $20? The real deal costs like $100+ for the screen, those cheap knock offs dont work worth a dam! I installed one and did everything right, the wrong number selects the slide up and down dont work. Its a pos. You get what you pay for.
