It’s the screen. The only ones that will work perfect everytime are original refurbished screens. Most resellers such as iFixit, Mobile Sentrix, Injured Gadgets and Mobile Defenders label these as premium. The average cost is 30 to 40 bucks.
It sounds like you may have a possible motherboard issue. I have seen similar behavior across many manufacturers and it’s usually a video card issue on the board. The fact that it eventually comes on is a new to me. It’d try a few things first. Do you have your files backed up? If not, get them backed up. Unplug the laptop and remove the battery. Try plugging in the laptop without the battery and see what happens. If you have some spare ram to pop in, I’d remove the ram and put in some more ram to see if you have a ram issue.
I would try doing a hard reboot first. Hold down the volume button and power button until you see the Apple logo. If that doesnt work, try plugging it into your PC or Mac to see if it’s recognized. Lastly try reseating all connections. If none of these work, try another screen to rule out the replacement part going bad. You could have a short on VDD main or some other short that could be causing the phone to not take a charge. Hopefully one of the above steps fixes the issue, because a short will require microsoldering repair.
Unfortunately, without finding someone inside of Egypt that has an SE battery youre out of luck. Only batteries designed for the SE will work. Is customs blocking even aftermarket ones or just ones with the Apple logo?
It’s hard to say, if a replacement will work. It sounds like it should given the fact that if you tap the screen first it works. However, I have seen many chrome devices have backlight issues that originate from the motherboard. Here’s the guide for the screen replacement. I would reseat the cables to the screen first just to see if that works. Google Pixel C Screen Replacement
Have you tried a new toner? Also, the fuser is more than likely gone bad and needs to be replaced. When the fuser goes bad it doesn’t melt the toner to the paper properly. I’d order a maintenance kit for this printer.
One of the main reasons the replacements are expensive is because the screen the watches use is an OLED. The series 3 is still very expensive ($140 ish) depending on where you get them. If you wait, the price will drop some but don’t expect a huge price drop.
