Hello. I’ve never seen this on an iMac before. If the computer turns on but the screen stays black then you’ve probably got a broken LCD. If you don’t have a warranty then you could try replacing the LCD.
Hello. You could try replacing them but that’s a job for an expert. So unless you are a pro at motherboard level repairs then there’s no way to fix it unfortunately.
Hello. Try reconnecting the flex cables and see if it works. Otherwise check the cables for damage and sharp bends etc. If you can’t get it to work then get a refund and buy a different digitiser.
Hello. Yes I can confirm that the cellular and GPS screen work together. I did it myself and the both worked on each other. The cellular screen appears to have an extra antenna or something like that from what I can see.
Hello. Try restarting the update if you haven’t already (Hard reset the phone by holding home and power buttons together) Otherwise if you are able to force restart the phone it may cancel the update. Then you can backup all your photos and other data. After backing everything up connect the phone to iTunes and restore it. Then you will be able to restore the backed up files and have the phone updated too. Hopefully this works.
Hello. Just try keeping it on charge for an hour or so. I’ve had this happen before. If the replacement battery didn’t even make it boot then it might be something else wrong though
Hello. Sounds like you may have damaged some of the components on the motherboard. Check that all connectors are correctly connected and look for any possible damage to the motherboard. If it is damaged then your better off replacing it, but it could just be that the connectors are loose or not put on properly.
Hello. Just try restarting your iPod. If that didn’t work then you could reset the iPod with iTunes if you think it is that much of a problem. It should just be a software error
Hello. From a quick search on Google I can see that there a several reports of audio problems with the Galaxy A8. Perhaps contact Samsung and see what they can do. It seems to be a complex problem.
