So, in 2017, I brought my iPad mini 1 in for a digitizer/glass replacement after I cracked it and after they fixed it, I...

So, I’ve had this issue for a while, it’s when the controller turns off randomly, when I turn it back on, it just blinks...

I’ve bought this computer in 2016 as a refurbished device from eBay, today it made a popping sound and won’t turn on and I...

Error 9 is a common issue caused by connection issues. This may be caused by that capacitor you said that had “pry damage” or it might be with the Lightning Cable you used to restore the device and it can be a loose connection between the charge port and the Logic Board, you can get free schematics and board view from the internet just make sure the schematics and board view you are downloading doesn’t look shady, or you could get payed schematics and board view. Did you make sure to unplug the battery before disconnecting anything else? Did you properly plug the battery back into it’s connector? Let me know by commenting on my answer if those steps helped you fix it or not.

This might be a power supply or motherboard issue, to identify the issue, is the red standby light on the TV on? If so it might be a motherboard issue, before you order any parts assuming that is the issue, try unplugging the TV and hold down the power button on the TV for 1 minute, THIS HAS TO BE ON THE TV NOT THE REMOTE, after 1 minute, this will drain all capacitors inside the TV, plug it back in and if it still does not work, call or email Samsung about the issue and see if you have warranty on the device, if your TV’s warranty has expired, then diagnose the issue and use a take apart guide on YouTube or iFixit itself. This may be a power supply, or a motherboard issue.

If the isopropyl alcohol doesn’t fix it or you don’t have it due to a pandemic, you can mail it in to Jessa Jones (iPad Rehab). If you do have isopropyl alcohol, then take the logic board out, soak it and with a tooth brush, just scrub it.

I found a short on one of the capacitors and when I plug it in, I found that a chip was very hot! Almost burned me, what I did was remove it and I was shocked to see it work again, when I plugged it in, the fan started spinning and it booted to the OS. Thank you for your help!

There is a fix for this. As there is a repair guide, you should be able to repair this issue, firstly, the touchscreen may be a bad connection to the motherboard, id advise you to first find a repair guide for the Galaxy TAB 4, secondly, once you feel confident, you then take off the back cover, find the touch/lcd connector, take the connector off, put it back on, if this doesn’t resolve your issue, then buy a new screen, put it on the frame. If this doesn’t fix this issue, then it needs board level repair, secondly, check the volume buttons, are they connected right? Check for that, you can find replacement parts anywhere, and good luck on your repair! Merry Christmas!

Might be a home button gasket loose, or the home button cable might be loose, you can buy a gasket here: iPhone 6s and 6s Plus Home Button Gasket Without replacing the gasket, the home button will feel loose and that might have ripped the cable. Open it up and check the cable, if it is the gasket, you can replace it easily.
