Rispondi a "iPhone searching signal constantly"There is a copper contact on top of the antenna cable at the top of the phone logic board and there is a little mesh pad that had moved off of that contact, I will include a pic but I peeled the pad back up and put it back on the copper and now my phone is no longer searching. I put a meter on that mesh pad and it does conduct electricity plus I could see the outline where it should have been. I was smacking my phone hard to get it to stop searching and it would work sometimes for an hour sometimes for a few hours but I think it's fixed now.
Rispondi a "3 beeps on start up"OK, I have an older MacBook air model a1237 that chimes then about 10 seconds later 3 beeps over and over. I pulled the logic board and looked it over with a magnifier several times and it's real clean no parts look bad so I put on new thermal paste and still have 3 beeps BUT I figured out by timing the boot process, turn it on and after it chimes and when the screen lights up push power to turn it back off then hit power a second time and it boots fine. I did this about 20 times and it boots that second time every time. So when I want to use it, hit power, wait for the chime and hit power to turn it off then hit power to boot. Don't know why it works but for this MacBook, it just does. Tried booting with the disk drive out and same thing so it's not a software issue, something with the board but at least I got it to boot. Just FYI, when you power it on and it chimes and as soon as the screen lights up it is approx. 8 seconds and you should see the apple logo.
Rispondi a "Constantly searching for signal."Only way mine stopped searching and connected is if I slam it into my open hand real hard a couple times and it will work for a day or 2 then back to searching so slam it again, something is loose or?
