Try tapping the FN + F8 (or other key that has crt/lcd or monitor) on it. Can you hear windows chimes? If you can hear the system fully boot up, but you have no video through the LCD on the system, try using the video out- or another monitor. If that does not work- there's a good chance that the video card/ video chipset on the laptop's motherboard has gone out. I would recommend contacting HP tech support if your system is still in warranty at that point- since if it isn't- as a minimum, you are looking at a fix that may cost as much or close to as much a new system.

Troubleshooting Flat Panel Monitor issues.

Screen is blank and power indicator is off

The monitor is possibly not receiving power. Perform the following steps to fix the problem:
  1. Ensure that the electrical outlet and the monitor are both switched on.
  2. Check that the power cord is firmly plugged into the electrical outlet and the power supply unit.
  3. If the power cord has a removable fuse, replace it.
  4. Try another power cord.
  5. Try another electrical outlet.
  6. Check the power connection at the back of the panel.
Screen is blank and power indicator is steady green

Brightness and Contrast may be too low. Adjust the brightness and contrast using the On-screen display controls (OSD) by selecting the button
Screen is blank and power indicator is steady amber

The monitor is in the Power Management Standby state. The power management feature is invoked when the computer recognizes that you have not used your mouse or keyboard for a user-definable period. Perform the following steps to bring monitor out of the power management state:
  1. Press any key on the keyboard or move the mouse to restore operation.
  2. Check the Power Management software on your computer.
  3. flatpnlmont12.jpgPress the (OK) key to switch between analog and digital mode. If the panel is the wrong mode for the signal being provided, the monitor appears to go into sleep mode.
Screen is blank and power indicator is flashing green
Display mode of the computer is outside the range of the monitor. The display mode the monitor uses is controlled by your computer. Therefore, you should refer to your computer's documentation for details on how to change display modes.

The image size, position and shape may change when the display mode changes. This is normal and the image can be readjusted using the IMAGE SETUP and the monitor controls.

Note: Unlike CRT monitors, which requires a high refresh rate to minimize flicker, TFT technology is inherently flicker-free. If possible, configure your computer for 1600 x 1200 addressability at 60Hz vertical refresh rate.

Use the following table as a guideline and reconfigure your computer to use a supported display mode. The highest resolution (for example, 1600 x 1200) produces the optimal output, but limitations of your monitor may prohibit this setting. Adjust the addressability mode until an image appears.

CHECK SIGNAL CABLE" message is shown and power indicator is steady amber.

The monitor is not receiving a video signal. Perform the following steps to fix the problem:
  1. Check that the signal cable is firmly connected to your computer
  2. Check that no pins are bent in the signal cable connector.
There are noises in the video signal. The IMAGE SETUP function is used to adjust the level of noise in the video signal which causes horizontal lines or areas where the image appears to be unstable and jitters or shimmers. This can be done automatically or manually.
Note: It is not applicable to digital input.
Use the image setup fix the problem:
  1. flatpnlmont6.jpgSelect (Image Setup) menu in the OSD.

  2. Select Manual to adjust CLOCK/PHASE settings.
Image appears to be discolored

The color setting may be incorrect. Perform the following steps to adjust the color settings:
  1. flatpnlmont8.jpgSelect (Image Properties) from the OSD menu.
  2. flatpnlmont9.jpgSelect (Color Properties) to adjust the color mode you find most comfortable or fine tune the colors using the Custom menu.
A few dots are missing, discolored, or inappropriately lighted

A small number missing, discolored, or lighted dots may be present on the screen, which is an intrinsic characteristic of the TFT LCD technology and is not an LCD defect.
Using On-Screen display (OSD) controls
flatpnlmont12.jpgThe settings adjustable with the user controls are viewed through the OSD. Press the (OK) button to display the main OSD menu.
OSD main menu:

Note: The LCD monitor needs time to become thermally stable the first time you turn it on each day. Thus, to achieve more accurate adjustments for parameters, allow the LCD monitor to warm up (be on) for 15 minutes before making any screen adjustments

Green Power light blinking


Check the resolution in the Windows while connected to the old monitor. If greater than 1280 X 1024 and/or the refresh rate exceeds 75 Hz, the monitor may not respond. But you should at least see the BIOS splash when the computer is turned on. If that does not appear, maybe a problem has occurred in the monitor. Another indicator: if you turn the monitor power button off and then back on, you should get some sign of life such as "no signal", or "out of range". If nothing appears, that would indicate some problem within the monitor.

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!

LED Display gives you your display visual alerts, signal strength, and operation mode. Here is an attached link for the manual.....http://www.uniden.com/pdf/LRD6399SWSom.pdf
But to answer your question here is what the difference between the green light and the red light are:
1. X-Band Signal Indicator—A green LED lights and blinks to
indicate the presence of an X-band radar signal. The blink rate
increases as the radar source gets closer. A distinct audio alert is
also heard.
2. K-Band Indicator— An amber (orange) LED lights and blinks to
indicate the presence of a K-band radar. The blink rate increases as
the radar source gets closer. A distinct audio alert is also heard.
3. Ka-SuperWideband Signal Indicator— A yellow LED lights and
blinks to indicate the presence of a Ka-SuperWideband radar
signal. The blink rate increases as the radar source gets closer. A
distinct audio alert is also heard.
4. Laser Signal Indicator— A red LED under L lights and blinks to
indicate the presence of a laser signal. A distinct audio alert is also
heard.
5. SWS Signal Indicator— When an early warning hazard or
informational signal is detected, the yellow SWS LED begins to
blink and the amber K-band LED lights. A distinct audio alert is
also heard.
6. Power-On Indicator— A green LED under P lights to indicate
power is being supplied to the unit and the unit is turned on.
7. LED Signal Strength Meter—Four LEDs give an accurate visual
indication of the strength of radar or laser signals.
8. City Mode Indicator—A green LED under C lights to indicate
that you selected City Mode.
9. Auto Mute Indicator— A red LED under M lights to indicate that
you selected the Auto Mute feature.

Please make sure you give me a rating and I hope this helps,

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.

Monitor Black, Green Power Light Flashes Monitor is 4 yrs. old


Assuming you've already checked your driver and system settings, tried a different monitor, and checked the cable and connector pins, this would almost certainly be a problem with the power or signal circuit board inside the monitor.
