    The monitor was working until two days ago when I truned it and the computer on I could hear the computer loading,but the monitor just showed the green "no signal" a few seconds and went black I conected the digital cable(no damaged pins in conector) from the monitor to my notebook computer with the same results. Whats wrong?

Solution: Replace cap. Radio Shack sells a 1000uF, 35V cap for $2. This will work.

Why did the cap go bad? The cap is too close to a heat sink and over heated.

What does this cap do? This cap sends a signal to an IC which keeps the monitor 'on' after the power switch is pushed. When the cap is weak, AC ripple voltage is applied to the IC and it sends a signal to shut the monitor off.

Opening the Monitor: These monitors are difficult to open.

The two plastic pieces snap together and must be pried apart with a flat screw driver.

After removing the stand, you need to insert a flat screw driver at the bottom of the screen where two slots are located. Then work the screw driver around until the two plastic pieces are separated.

Remove the cover plate and unscrew the push button circuit board.

Unplug the monitor cords from the driver board and remove the screen.

Unscrew the mounting screws from the power supply board and remove.

You will need to pinch the plastic support in the middle of the board to remove.

Cap Replacement:

Cap is located near a copper heat sink and the value will be on the side of the cap. It will be bulged up on the top. You will see burn marks on the board surrounding the cap. Unsolder the cap.

Install the new cap and solder. Make sure you connect + of the cap to + marked on the board.

Be careful not to solder across joints.

Keep leads long so you can bend the cap as far away from the heat sink as possible.

Reassemble monitor and turn on.

This should solve the problem.

Are you using the digital connection?? If so try using both the analog and digital connection then set the digital as the Main monitor in your graphics card interface. Next time please include more details, such as - did the monitor ever work for you? Is this an installation problem? Good luck

the computer and the monitor.

I have a shap lcd computer monitor and when i plug it into my computer and turn the power on, the little green power light comes on, screens back. and after 5-10 seconds the light turns orange and blinks...


It could be your monitor is fine. It simply goes to a cycle when its turned on and does not detect any signal coming from your CPU, it simply goes on standby mode (hence the darker image and orange/blinking light.) have you checked the computer (CPU) part?

Pc wont read monitor


If you look at the monitor there will be an led light on the front that is always orange or yellow when the computer is off but still connected to the monitor. This led will turn green when the computer boots up, sometimes even showing a "no signal" display before boot. If you see the 'command line'  text during the boot process (video info, BIOS version, POST text, etc) then the monitor is being recognized by the computer. If that text goes away and the led goes back to orange then it is a driver or operating system problem. Pressing whatever key is prompted at the lower left of the display, if you have a display, like F1, F2, F10, Delete or whatever will get you to the setup program and all is good with the display/computer connection and a green light will stay on. If you never get that green led light then either the video card is bad or not seated properly

No display


if your monitor is not connected to a pc, then it cannot find a vga signal input and therefore go into power saving mode, which is indicated by the orange light, but as soon as you connect to the pc and power on the light will go green and the monitor will power up.
