Question about SGI Silicon Graphics GDM 4011P 20" CRT Monitor
My SGI GDM-4011P monitor doesn't want to turn ON. But sometimes, it does! I've already turned off Power Save Delay options,double checked connections, etc., but just don't know how to 'predict' if it would turn ON when I push the Power Button. If I wait something like 1 or 2 or more days of not using it, it would sometimes be turned ON. It's really puzzling, could you help me please?
I think you have a faulty Power Supply, more than likely it is gonna be my old favorite faulty Electrolytic Capacitors, Intermittent problems are real tricky to fix, If ya handy you could try opening it up and having a squiz, look for any loose connections or "Swollen" Capacitors see if all the "Lights" are on etc, try gently "Tapping" around maybe it's a "Dry Joint" but my money is on the PSU. If ya can see a problem say Faulty Electro's replace with the same or better Temperature rating ... Good luck

Tips for a great answer:
Hi hope your monitor issue has resolved. I would suspect the
problem is a hardware issue then a software setting. Since the monitor is over
three and half years old, if your monitor is a LCD with CCFL back light and had
been used almost every day, there may be 3 possible hardware issues. First is
the internal power supply, that can go wrong due to heating problem within the
monitor, this problem usually cause the monitor to display poor quality picture
and may show interference lines on screen prior failure. Secondly, it may be
the inverter that drives the back light, which may fail due to the safety
circuit kicks in, because it involves with high voltages. Thirdly it may be the
backlight itself, which is like most compact CCFL energy saving lamps that
flickers or turn itself off when it reaches the end of its service life. This problem
usually caused the monitor to show redness or yellowness images prior failure.
All of these can be resolved by qualified electronic repairers, all the best.
