Question about ViewSonic VA2012WB Monitor
My monitor goes black after about 30 minutes and it will come on again if I turn the power off but will not stay on for long????
Has been doing this for a few days now ??
It has been quite hot in the room about 80 degrees??
You may have failing power supply due to bad DC filter caps and also poor solder joints on the board, look for dark brown spots on the power supply/inverter board.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed VIEWSONIC monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
