I was playing one game on my 6630 (v 2.39.15) when backlight suddenly went off. It came back after cca 20 mins while i was playing the same game (i taught that its some catch in the game) but 15 mins later it went off for good. Now its 20 hours that i cant get backlight on, i tried everything browsing settings options, i ve restarted my phone (*#7370#) but i cant get back it on. Should i go to repair centre or do you thing maybe its some bug that can be fixed. Thanks.
6630 backlight off
Sounds like a hardware fault to me. Meaning: repair/service center is the way to fix it.
