Hello,
I have a similar problem but I’m not sure about the reason for my non-working display: The display port still works but recently the display itself finally faded out (although it had a temporary comeback in between).[br]
[br]
There were some warning signs before, e.g. less brightness in one corner and in general, shortly before breaking. A few times also screen artifacts appeared: The whole display turned dark brownish as if there were a fluid which spread over the display from top to bottom. Anyway, after a restart this wasn’t the case anymore.
So, can anyone give me advice about what to test now systematically ? I didn’t find a plan of the LCD Sync/backlight port pins to measure the voltage.
