Hi all!
I'm trying repair monitor. Dell U3011.
Have some expirience with electronics.
Describe problem:
- this start year ago, not in all power on cases backlight start working, fix with some switches power buttton (1-3 times)
- month ago, backlight was go off, in 2-10 minutes after run, after this cycles (pwr on <-> timeout <-> backlight off ) set stable mode and can work weeks without power off.
- now it can't backlight on 20-30 power cycles, but on next day can be runned in one time and good working before power off, it's totaly random case...
