tricky!! oh hi im Dyanne.. a totally unresponsive black screen can be th result of failure of th LCD or LCD inverter.( a specialized piece of electronics that energize th screen) to rule out th failure of th video display adapter or circuitry, try plugging in an external monitor..a standard pc monitor.. attached direct to th lappy. if it works, (as i susopect) th motherboard and video display are both working ok and its th LCD which is at fault. this can sometimes be repaired by a competent specialist. good luck xx

SOURCE: Computer monitor becomes distorted after boot up.


Download and install the correct driver for the monito as well as the deiver for your video card, if the video is onboard, you may need the motherboard and AGP driver as well.
You will probably need to boot in Safemode to do this.
Good Luck.

SOURCE: computer only displays vertical lines and pink background.

Most likely an issue with the Video Card or Video driver.
* Boot to safe mode by tapping F8 while starting up the computer. Selected safe mode with the keyboard and hit enter. Login to your user account. You should see the words “Safe Mode” on all four corners,
* Open device manager – Right click “My Computer” – Select “Manage” – Selected device manager from the left. Under display driver, you should see your vide card listed. Right click on it and select “Disable”.
Now restart your computer and if this resolves the issue, then the vide card may be at fault. You could also try updating the video driver.
Do let me know if you get this far.

SOURCE: I hadn't turned my hp

1) There is a such thing as a bad Power Supply. New or not.

2) You may not have all required power cables plugged in.

Besides the ATX main power cable, there is also a 4-pin ATX +12 Volt power cable, that has to be plugged into the motherboard.

This cable,

This is HP Support, and the Motherboard Specifications page,

I would like you to scroll down to the illustration of the motherboard.
To the left of VIA KM400A is a small square. To the top of the small square is printed ATX12V
This is where the 4-pin ATX +12 Volt power cable plugs into.

(The motherboard chipset is the Northbridge chip, and the Southbridge chip.
The VIA KM400A chip is the Northbridge chip. Should be under an aluminum finned Heatsink)

I would also like you to clear CMOS Error codes.
Computer unplugged from power press the Power On button, and hold it in.

Hold it in for a count of 5 seconds. (And I mean at least 5)
Let go of the Power On button.
Do this procedure 2 more times.

This action will clear CMOS Error codes, and reset BIOS back to the factory default settings.
Plug the computer back into power. WAIT 1 minute, then turn the computer on.

Be sure ALL power cables are plugged in, and plugged in tightly.

A) ATX main power cable. (20-pin ATX main power cable)

B) 4-pin ATX +12 Volt power cable

C) All 4-pin standard Peripheral power cables.
1 is for the Harddrive.
1 is for the CD or DVD optical drive, ( Or 2 if more than 1 optical drive)
1 may be used in conjunction with an adapter cable, and used for power to a computer case fan.

3) Make sure the ram memory module/s are seated in tightly. (Module = 'Stick')

You may wish to clean the gold plated contact pins on each ram memory module.
The gold plated contact pins develop corrosion.

Computer unplugged, and you have followed Anti-Static Precautions, remove each ram memory module.
Use a pencil eraser to clean each contact 'strip'.
If you use an eraser on the end of a pencil, refrain from letting the metal band contact the contact pins.
Just takes a few strokes of the eraser on each contact pin.

After you have finished cleaning a contact strip it may look as though you have done nothing at all
I assure you that you have. Doesn't take much corrosion to make a bad contact.
Use air to remove the eraser dust before you reinstall the ram memory.
If air from a can of compressed air for computers is not available, air pressure from your mouth is sufficient.

If this doesn't solve the problem please post back in a Comment.
We will go on to test the various voltages coming out of the Power Supply.

(If a multimeter is not available an economical unit can be purchased. Most auto parts stores carry them, as well as a multitude of other stores. A $5 to $20 unit will do just fine.

The voltages involved are 3.3 Volts, 5 Volts, and 12 Volts.
ALL are DC voltage.

Two D cell flashlight batteries produce 3 Volts DC )

Black screen just after boot window from USB

Sounds like either the monitor or video card inside the computer is bad. Try connecting another monitor to the computer. Borrow a monitor from a friend, neighbor, relative or co-worker and plug it into the computer. If the borrowed monitor displays ok, then your original monitor is bad. If the borrowed monitor does the same thing and not show a display then your video card inside the computer is bad.

have you tried going to your device manager and hardware if you look for your graphics adapter uninstall it then look for hardware changes then it should find it again and reinstall drivers.

HCM Monitor has no display. When monitor started it becomes on but no display.All the function LED Becomes on.

Try disconnecting the monitor from the video connection.
Disconnect the power source and allow to set for several minutes.
Plug in the power source only and see if you recv. a no signal message on screen.
If not, you most likely have a bad display board or back light problem.
If you do recv. the message, you have a problem with your video card.

My become like horzantal lines+become not

Disconnect the Monitor from the PC, and keep it still powered on. If it displays horizontal lines, it means monitor has gone bad. If not then go to PC's BIOS, if it shows lines there then your graphics card/chipset has gone bad. Else its your graphics driver/operating system. Can try an update/reinstallation of driver.

LCD monitor have Vertical lines and black colour become greenish

normally the 19" resolution can support up to 1280*1024, but if it comes with vertical lines in full screen, it might indicate the panel is no longer to work and probably it's time to replace new one.

My screen becomes yellowish..

Have you checked you monitor settings on the monitor? You may try setting you monitor the factory default and then re-adjust from there. Have you tried upgrading your vidoecard drivers? I would 1) Check actual setting on the monitor. 2) Make sure you are using the proper monitor drivers. 3) update your video card settings. Let me know what happens. Good Luck, Tim
