Question about Samsung Viewsonic VG700B Monitor
I suggest you connect the VGA cable from the computer to another monitor or a laptop, just to make sure that your monitor's back light is faulty. If it does show on the other monitor or laptop, then the back light is really faulty. And i suggest that you get a computer technician to open it up for you if you can not do it yourself. Or you can get a sharp-flat object and open the monitor starting from the bottom of the monitor working your way round to the top. You will notice finger-like structures that hold down the monitor covers together. Make sure you do not break any of those. When you open it, check on the circuit board where you connect the power cable. Check for any bulged or leaking capacitors. Capacitors have a job to hold down the power from the source long enough for your display. For faulty capacitors, the monitor will either remain black with the orange light blinking, or it will display for at least between 2 to 8 seconds and then goes black. Buy the same type of capacitors and replace the damaged ones. Please not the polarity as you replace the capacitors.. Good luck
