After replacing a defective screen [see here], it worked fine. However, a couple of weeks later, the device ceased to work properly:
- Sometimes when I power it up, it doesn’t show anything on the screen, while sound works
- Sometimes it takes about 20 seconds from power-up for the startup sound to be played; screen doesn’t work here either
- I replaced the screen with a new one I have, and now the screen is not blank – rather it’s black. If I look at the screen in ~15° I can notice the image [see a short video of this here].
The reset trick didn’t work this time.
