i have the same problem. i cannot see 2.4ghz wireless networks. I changed many components including f tri chip on the 2.4ghz antenna line. still weak. my last resort is replacing the wifi chip. Any suggestions would be appriciated. i also check up top near the standoff screw where small silver antenna connect to phone frame. all inductors and caps have been replaced including f tri chip.
i cannot find c2020 on the iphone 6 plus schematics. Can someone telling me the value of this component as i accidentily knocked it off replacing my lcd now i have a partial dark spot on the lcd. Need to replace that part. Any help would be appriciated. thank you.
The backlight ic ic located under the EMI shield, where the Cpu and power IC are located. In order to replace a backlight IC for ipod touch 4th gen u have to take off the entire emi shield and also the metal piece under it. You have to carefully break it off, i have done this many times but it takes patience. Once you do that, its located on very top right hand corner near the PMIC Thanks
