The on/off of pc monitor (LCD) is blinking.

Most LCD monitor (depends on the brand) power indicator light will either turn from Green to Amber, or flashing Amber, or flashing green, when it does not detect video signal feeding it. So it may be normal with your monitor. Are you haivng problem with the display? If it displays he pictue OK then there is nothing to worry about.

Hp l1906 LCD MONITOR SCREEN WONT DISPLAY. power lcd green light keep blinking. Any solution? thx

It is possible that the video card in cpu is bad, try hooking up another monitor to the cpu (computer) if you have one that will let you know if it is the monitor or the computer video card, Could be as simple as the driver is missing.

Dell flat screen started flashing, green light was blinking then screen went blank and green light is on. Tried unplugging etc...time for a new one?

No. It is not a Flat Screen issue. It is a CPU issue. You CPU is not sending signal to your flat screen so the green light is flashing. Try to:

1. Reset OR
2. Unplug the CPU case, Open the CPU, the interchange the RAM modules, OR
3. Same with step 2 but unplug and then plug back in all expansion cards like audio, video cards, etc.

It seems that your system needs discharging from a frozen state.

NEC mutisync LCD 1700m Flashing/Blinking

You have an intermittent problem. That means a component is going bad in all probability. If it was a capacitor that burned up you would not have any picture. Your problem requires a schematic plus an tester. You would need to check values for all components. If you have not done this (and assuming you can follow an electrical schematic) and if new to diagnosing these types of problems plan on spending many hours at the task. The question you need to ask yourself perhaps is is it worth it.....particularly since even if you find the problem it may require ordering parts...and you might need some basic soldering skills, etc.....If it was me...I would probably either send it in for repair (deifnitely if under warranty) or buy another.
