ОтветыMicrophones work, but not during phone calls.I have the same issue on an iphone x. I also had it before on an iphone 6. I never thought it could be something on the board. With the iphone 6, i replaced everything inside it and it was still doing the same. I now bought an iphone x second hand and the warranty expired just a few days before i got it. I took it to apple to replace the battery. I never noticed the mic issue before. So either the apple guy did something wrong and screwed something or did not connect a plug properly or there is something wrong with the board. I tried restoring, updating, even resetting and not using a backup. Sometimes it seems it works temporarily. Both this iphone x and that iphone 6 has the exact same issue. Mic is working while using memos and sometimes works in calls as well but randomly it stops working while in call. Putting the phone on speaker and taking it back off, will make the mic work again for a while. Sometimes it happenes very rarely, other times in every call once at a few seconds. I do electronics repairs, ...
ОтветыHorizontal lines on screen - red screenHello. Have you fixed this? I am an engineer with the proper tools to do advanced hardware repairs and i have a macbook with the exact same issue. Unfortunately this one has had an attempted repair before. Did yours broke while you were using it? Did it happen suddenly? I have tried reballing the GPU and the VRAM modules without success. I am waiting for a new GPU to arrive in post so i can replace it. Will keep you updated. Please let me know if you fixed it, sold it for parts or took it to apple replacement program (which is not active anymore for this laptop model ) Update (12/24/2018): I replaced GPU and video ram and the issue persists. In my case i noticed that the heatsink was damaged and not doing its job properly, this way both the cpu and gpu were ar much higher temp then normal. I suspect that over time this caused some permanent damage in the board. Some pads maybe not making connection anymore from the gpu to the vram. So in my case its unfortunately not repairabile
ОтветыUpdate file corrupted su-30645-8 on usb with new hard drive.it;s a hadware problem on the motherboard. i am trying to figure it out for 2 months. i have replaced the processor and syscon/nor with a working one and it's still the same issue. i have moved the original chips to a good board and it works. so don't bother anymore unless you do smd rework Update (08/30/2016): I have cracked this issue. The problem is hardware related, more exactly ram related. When you want to update the software, first the console copies it into ram an then it writes it. If a ram module is fulty it will mess up the file at binary level, so in conclusion the md5 will be different so the ps4 reports the file as corrupted. The only way to fix this issue is to replace the faulty ddr5 module/s. Unfortunately, unless you see any phisical damage, there is no way to determine which of them is faulty so you have to replace them one by one. I auggest starting with the ones on the back. Warning: unless you have professional equipment and necessary skills, do not attempt this on your own, because you ...
