How to Solve iphone 6 plus White Stripe Screen Problem

Last weekend, my customer send  a dropped iphone 6 plus, that had problem about touch screen. The touchscreen had been unresponsive and display white stripe. Vipprog engineer was aimed at his problem gave her iphone 6 plus lots of solutions. Now I will sort out these solutions for you. Hoping you will benefit from it.
ISSUE:
A dropped iPhone 6 Plus touch screen does not respond like it should be sometimes.  The white stripes appear when touch screen is not working.

SOLUTION:
1. IPhone 6 Plus touch screen sometimes responds while sometimes not. And the white stripes appear on screen. This kind of problem is common in iPhone 6 Plus. The dropped iPhone 6 Plus is very likely to have such problems, as shown in below picture.

2. The reason is that the pin M1 of touch process chip U2402 almost disconnects. The pin M1 is used by synchronizing signal to communicate between LCD and touch screen control chip. If the synchronizing signal does not synchronize normally, the touch screen will not respond. Remove the touch process chip directly, finding pin M1 has been taken down along with the touch process chip, as shown in below picture.

3. After knowing the problem, it is much easy to repair. Solder a Jumper wire at the original joint of pin M1, as shown in below picture.

4. After the wire is done, solder the touch process chip U2402. Turn on iPhone and get into test on IOS. The touch screen can respond now. Trouble is removed.
