    Looks like hard drive problem.. CD drive has power HD has power but nothing boots up. CD drive wont load boot disk HD does not beep when system turned on.. Replaced battery on motherboard to reset cmos to default still nothing.. Suspect when I removed the power connection to hard drive and then reinstalled it.. I may have damaged HD.. after 8 years it's probably time to upgrade to new system anyway.. Thanks for the thoughts.

Dear,

To rectify your problem, Perfrom these steps.
Self-Test Feature Check (STFC) Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
  1. Turn off both your computer and monitor.
  2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove both Digital (white connector) and the Analog(blue connector) cables from the back of the computer.

The power lite goes on and off and screen wont lite up


telepathy do not work, you need to state what computer brand, what model, what monitor, meantime follow that procedure:

1. switch off computer and monitor
2. disconnect all cables on the back of the computer and monitor
3. re-connect all cables
4. re-power your monitor (is light on? any message on the screen?)
5. re-power your computer - is there any activity on the screen?

if there is no joy:

6. change monitor for known working one and check for display,
7. connect your monitor to known working computer,

is there a display on your monitor? is there a display on borrowed monitor?

if there is display on borrowed monitor, that mean that your monitor is at fault, especially if your monitor do not work on another machine.

if neither monitor work on your machine but both work on other, this will indicate video card at fault (most probable) or motherboard, or memory all of these need to be assessed before further proceedig can be advised.

before further help is sought, state clearly what computer, motherboard type and model (all in one?), video card model, monitor model

if you find this advice helpful, vote for me

Computer monitor wont turn on when you hold the power button a small orange light turns on. What is wrong?!


CONNECT THE MONITOR DIRECTLY TO THE WALL OUTLET
CHECK WHETHER YOU GET CHECK AUDI SIGNAL OR NOT OR ANY MESSAGE---HTEN CHECK FOR THE CABLE---IF STILL THE ISSUE PERSISTS CHECK IT WITH A DIFFERENT CABLE---
THEN CONNECT IT TO THE COMPUTER MAKE IT SURE THE COMPUTER IS TURNED ON AND THE POWER IS GIVEN TO THE MONITOR AS WELL----CHECK THE COMPUTER WITH ANOTHER MONITOR---IF THE OTHER MONITOR IS WORKING FINE THEN CONNECT YOUR MONITOR TURN IT ON AND THEN FLASH A FLASH LIGHT OR TORCH LIGHT AND THEN SEE IF YOU CAN SEE A DISPLAY INSIDE..
WHILE CHECKING FOR ALL THESE STEPS YOUR ISSUE WILL BE RESOLVED IF NOT TYOU GOTTA CONTACT THE MANUFACTURER FOR A FAULTY MONTIOR---

STEPS IN BRIEF:
DO A MONITOR SELF TEST
CHECK FOR THE LIGHTS
CHECK FOR THE CABLE
CHECK FOR THE PHYSICAL SIGNAL
PUT THE MONTIOR ON A DIFFERENT COMPUTER AND CHECK
CONNECT THE COMPUTER WITH A DIFFERENT MONITOR AND CHECK
FLASH A FLASH LIGHT AS A LAST STEP TO SEE A DISPLAY
IF THE ISSUE IS NOT RESLOVED THE MONITOR IS FAULTY..
HAVE A NICE DAY!!!!

I have an hp pavilion dv5. When I power it on the computer starts up but the monitor doesn't come on. And then it does this series of beeps. Beep beep beep. It does that series 5 times


Before you begin
Check the following items before using the steps in this document:
•If you have a flat panel LCD monitor, unplug the monitor power cable, wait about 30 seconds, reconnect the cable and then turn on the monitor. This resets the electronics on the monitor.
•Make sure the monitor has power - the light on the monitor is on. If the light on the monitor is off, the monitor does not have power. Connect it to a different power outlet.
•If the monitor has a detachable video cable, obtain a second monitor cable for testing purposes in case the cable is bad.
•Disconnect all connected devices except the mouse, keyboard and monitor. This includes thumb drives and camera-type memory cards from card reader slots.
With the devices disconnected, restart the computer. If the computer starts and the monitor now displays a picture, a device is preventing the computer from starting. Update the BIOS to resolve this issue.
Step 1: Connect the computer to another monitor
Connect another monitor to the computer to determine which device has the problem (the monitor or the computer). This step is very important to help you determine if the problem is coming from the computer or the monitor. If necessary, temporarily connect the computer to a friends monitor for troubleshooting purposes.
After the monitor is connected, turn on the computer and the monitor. What happens?
•If the newly attached monitor does not display anything , disconnect the cable and continue at Step 2: Is the video connection damaged?
•If the newly attached monitor displays the first startup screen(s) but then goes black, there is a problem with Windows starting. Skip to step 5 .
•If the new monitor works , the original monitor or its cables are faulty. Do the following:
1.Replace the monitor power cable.
1.Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
1.Replace the video cable.
Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
1.If the monitor does not work after replacing the cables, replace or service the monitor.
Step 2: Is the video connection damaged?
Inspect the video cable and video connectors for damage. Check for sharp bends or breaks in the cable and bent or broken pins at the connectors. With the monitor and computer off, try to straighten bent pins with a small metal tube, like the tip of an empty mechanical pencil or the tip of a retracted pen.
Figure 1: Video connector
If you had to straighten any pins, reconnect the monitor making sure that the video cable is firmly connected and then turn on the computer and monitor. If the display is still blank, continue to the next step.
Step 3: Resetting and updating the BIOS
You can use these steps even though you will not be able to see anything on the monitor.
In case an item was changed in the BIOS, such as the primary display device setting, use the following steps to reset the BIOS back to its default configuration:
1.Turn on the computer and repeatedly press one of the following keyboard keys. Press the key about once every second for 5 seconds after turning the computer on.
◦For HP and Compaq computers that came with Windows 7 and Vista, press F10 .
◦For HP and Compaq computers that came with Windows XP, press F1 .
◦For Compaq Presario desktop computers built prior to 2002, press F10 .
1.Wait another 5 seconds.
1.Press the F5 key. This restores the default settings of the BIOS.
1.Press the Enter key. This accepts the changes.
1.Press the F10 key. This saves the changes.
1.Press the Enter key. This saves the changes and exits from the BIOS.
1.The monitor should display the first screens received from the computer (the logo screens). If not, find and download the latest BIOS update if one is available for your computer.
1.If a BIOS update was not available or the monitor is still blank, continue to the next step.

Monitor will not turn on.


Friend. Not a good news.
First check whether all the connection of monitor to the cpu is alright. If the connection is okay, then try connecting an external display and see whether display comes on or not on the external monitior. If yo get the display on the external, it means you have faulty monitor or video card. If you get nothing on the external monitor, it means your motherboard is faulty

When I turn my monitor on, the green power button comes on and then turns to amber. Nothing will display. What should I try


You need to check your video card. Check if it is still ok and functioning properly. You can also try checking your memory card. that are the two pieces usually causes that problem. Try this :

1. Double check the cable that connects the monitor and video card. Remove the connection of your monitor to your CPU (the video card cable is what i mean) then turn on your monitor. If the monitor displays a message like this " Check signal cable" it means it is working fine and there is a problem in your CPU.

2. This step is just for PC that are using PCIE or AGP video card,not built in there motherboard. Remove your video card if you have a PCIE or AGP video card, using an eraser (pencil eraser) you can clean the connectors of your video card (the coppers that is use to connect it to motherboard).

3. Try to remove your memory card. And the same as what you do in your video card, use an eraser to clean up the copper connector of your memory.

4. Put it all back in place. Make sure it is properly connected. Then turn on your computer.

If your monitor is still not working, you may use an internal speaker so that you can check if there is a problem in your motherboard.

If you don't know the meaning of the beeps try to read my tips and tricks i have the beep codes there..

Montior in Sleep mode


Take out the newly installed memory chip... If your sure its compatable with the motherboard, reseat it correctly into it's slot and fire up the computer. OR try rebooting with just the old memory installed. Monitor blackouts happen when the incorrect Memory is installed OR when the Memory is not seated properly.
stop chasing video and monitor problems...... :)
