iPhone5 struck on apple logo and then moves to a red screen...

In my case the issue was caused by the proximity sensor. Try disconnecting the sensor and booting up the device.

"I had the same problem, tested lcd while the phone was powered on. Got red screen and kept rebooting itself and then dying at a red screen continually.

Solution #1: hold the power button and home button for at least 60 seconds. The Iphone will try to restart but keep it held down until it stops trying to turn on. When u think it stopped trying to turn on then plug in charger and hopefully should work

Solution #2: dismantle, and install flex cables once again. Reassemble.

Solution #3: replace faulty lcd, OR replace the board, OR both"

I would take it back to who ever supposedly fix it and demand to get sorted!

The proximity sensor is the sensor in the phone that turns the screen off during a phone call. It is attached to the flex cable that includes the front facing camera and some other goodies.
