Fault: turning on does not appear。
Client description: the mobile phone used to show normality, with occasional white strips on the screen. Touches don't work. The client is more capable of handing out his cell phone. It's not welded back because of the limited tools. It doesn't show after two times. And then brush the machine with a computer but without showing it。
Maintenance process: according to the client's description, the first problem is the screws of the machine. The second is to touch the breakline or the empty weld. Let's get this straight. Fast-track and quick fixes test the computer, so that the online current jump is normal. The main panel was removed and observed under the magnifying glass. The left screw hole on the main plate has a sprain. As shown:
Slice the screwdriver, scrape it slowly with a surgical knife. The screwdriver could be too hard, and the pcb plates around the screwdrivers would be drummed up. It's like burning a bubble on your hand. This is the hardest thing to do, and the bottom line is cut off by accident. There's no way to fix it quickly but to scrape it out slowly, and three are broken. Add these three, and the ground-to-ground test shows a blockage. Ap to lcm reset conn l was found to be an infinity signal, even for cpu. As shown:
But there's no breakline at the bottom of the screwdriver. Find a pcb plate to sharpen the line. There's a point below the screws that connects the seat. As shown:
We got a spot. We got a spot. It's hard to get inside. There's no way we can just fly. Directly fly at point position to interface electrical resistance. As shown:
Retesting the seat barrier found normal, with the openings showing, but the touch was not able to use the flash screen. As shown:
Quick fixes began to touch。
The machine test, during which the camera was found to be inoperable, could not be switched back and forth. We'll get a back-up video. Think there's still a break! However, it was not possible to remove the software processing back set. Finally, the data can be restored and erased. As shown:
These are some of the fine maintenance posts that the quick fixer compiled from the fast-track forum, and more of them are in the fast-track forum. Forum web site: (chinafix. Com. Cn)
