Touch not working after new LCD install
I am a professional cellphone repairman and this issue has me perplexed. I bought an entire frame/lcd/digitizer replacement combo and very carefully transplanted all the componets. When I powered on the device the touch was not working. I figured the part was defective so I reinstalled the old LCD/digi/frame and now the touchscreen does not work on that either! There is only one cable that plugs in to the main board for both the LCD and Digitizer and I have absolutely made sure it is completely plugged in. HELP!
