My iPad Mini V1 screen started to become dim and very hard to see, while the battery area (backpanel lower half) went super hot.

I closed all the opened apps, and it's still the same issue. However, it won't become hot if the ipad is plugged in for charging, although the screen still was dimmed.

Then now, the screen went totally black. I have managed to reset the device and set it up as a new device, and yet still the black screen problem remains.

It's currently on the latest iOS8 as a new install, meaning no installed user apps. The system should be functioning although I can't see the screen because when I press on HOME button, and swipe, then when I click on the Power button at the top, I can hear a 'click' sound, which is expected when switching off the screen with the power button.

It is out of warranty and I went to a shop to ask about fixing it. Troubleshooting it costs RM80, and if it's the LCD display problem it's a RM450 repair costs, but if it's soemthing else, then different cost. Won't know the exact problem until they test and diagnose it out.

Do you have any idea what's the problem and if it's still worth to repair it?

Thanks.
