Question about HP PC Desktops

1 Answer

Hello- I just purchased a refurbished HP 1740 17inch flat screen LCD monitor from Overstock.com. The display is great, however on occasion the screen goes white. It reminds me of screen saver and seems to be doing it when inactive for a while. But sometimes it appears to be doing it whenever I change applications. It stays white until I restart the monitor. Moving the mouse does not help. (It's done it once as I type this). I looked around-- one post said to delete the Logitech camera I'm using. For my son's games we installed the Nvidia drivers from their site. Someone else said the drivers needed to be updated. But when I go to the Nvidia site it says all are updated. My brother is a computer superfreak but he lives out of state and says he has never heard of that. I saw a couple of other blogs with people saying it has happened to them, but not many. Any thoughts?

    Hello Stellyx-

    So far I have deleted and re-installed an older video driver, deleted my Logitech program (someone said that might be the case- the software conflicts?), I have defragmented the C: drive, increased screen resolution, chcked all connections, and turned off the screen saver. Still a white screen every once in a while with no pattern as to when. Seems to happen more frequently as the computer is on which makes me think it's heat related. Still seems to happen, perhaps coincidentally when I change applications. I can push the "minus" button on the front control of the screen, it then goes from white to black, then it comes up again. Hubby is taking it into a computer service guy today. If he cannot fix it cheaply I will send the thing back. (First choice was to send it back but then I'd be without a monitor, and whose to know whether or not it's my computer causing the monitor problem...). Anyway-- thank you so much for trying, you're a doll!.

Hi Cmrix,

it does sound like a driver problem in fact id bet on it. Just because the latest drivers are downloaded does not mean they are the best thing for your display. For example i fixed a clients pc that wanted to play the world of warcraft game and the solution was to actually install an older version of the drivers for his video card.
Theres a couple things you may try but it requires that you uninstall the latest drivers and install an older version of the drivers. You can do this by uninstalling the card and/or replacing the drivers with older ones through the device manager(start menu>control panel>system>hardware>device manager).

My other thoughts on troubleshooting this is to make sure that my screensaver was turned off and see if that fixes anything. what bothers me about this is that it happens while your using the pc (moving the mouse, using the keyboard etc).

It might also be a bad connection of some sort so you might replace the monitor cable, re-seat the vid card etc.make sure nothing is lose.

I hope I helped

Will my hp pavilion a 420n support a 19" flat screen monitor


Hello,

I have to assume you are currently using the larger size called a tube type monitor and would like to have an LCD or flat screen type monitor connected to your computer.

To connect to new LCD flat screen monitor to your computer would be exactly the same connection as what you are currently using.

The only problem you could run into is the connector itself. Some of the flat screen LCD monitors do not have the older style connector called VGA, usually blue called DB15, because it has 15 pin connector. They may have only have the newer style called a DVI type. Some do have both types.

Please be sure the LCD you want has the older style DB15 connector to connect to the rear blue VGA input of your compter.

Good Luck

I have a hp laptop. was on line and screen went black. and will not show again. it strats up sounds but black screen.what do i do


1) Do you have a VGA monitor that you can use for an external monitor?
{VGA monitor is also referred to as a CRT monitor. Looks like a small TV}

The back of the laptop, or side, has a VGA port. The VGA monitor is plugged into it.
{Laptop off}
Then the VGA monitor is turned on, and allowed to 'come to life'.

Now turn on the laptop. Press the Fn key down on the keyboard, and hold it down.
Now press the Monitor toggle over key.
Since you did not state the HP laptop Model Name, and Model Number, I can only give you generic guidance on this.

The monitor toggle over key has a monitor screen symbol on it. It will be one of the F keys.

(It's an External Monitor toggle key.
Press it one time and the display toggles over to an external monitor.
Press it again, and both the laptop LCD screen, and the external monitor have a display on them.
Press it once more, and the display goes back to the laptop's LCD screen )

If display shows up on the external monitor, you have a problem with the display of the laptop.

Primer:
An LCD screen cannot produce enough light by itself. It needs an additional light source.
A Backlight is used as an additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp {Bulb}
Similar to the fluorescent lighting used in homes and businesses, but on a MUCH smaller scale.

{Average Backlight is 3 to 5 inches long, and half the diameter of a No.2 pencil.
The Backlight is located on one edge of the LCD screen}

An Inverter is used to provide power for the LCD screen, and the Backlight.

90 percent of the time the problem is the Inverter.

Inverters are relatively cheap, and if I knew the Model Name, and Model Number of your HP laptop, I could give you a link to HP Support where you could download the Service Manual for free.

This way you would have a manual to show, and detail how to replace the Inverter, and I could guide you.

I could also give links for your perusal for Inverters.

There is one more thing however.

HP Pavilion DV2000, DV6000, and DV9000 series laptops, have a graphics chip overheating problem.
The laptop comes on, the blue indicator LED lights light up, but the LCD screen is black.

This video explains why, shows a solution to fixing the problem, and details out a lot more than I am privileged to state here,

Hello i purchased a philips 20PFL4122 lcd tv/pc monitor and i have a problem when i set the resolution on my pc to 640/480 as instucted in the user manual the pages are to large to fit the the screen when...


I have bad news for you.

The monitor you bought (Great Price by the way) is working exactly as designed. The problem is the 640 x 480 resolution. Almost all internet content now days is scaled for either 800 x 600 or 1024 x 768 resolution. This is why every time you open a page you have to pan both left and right and up and down to see the entire page.

LCD monitiors are designed for a fixed resolution unlike CRT (TV Tube) monitors that can display different resolutions with equal clarity. This is why when you go to a higher resolution the screen is almost impossible to read.

Since your optimal resolution is 640 x 480, that is the only resolution that displays clearly. That is great for a TV, but sorely lacking as a computer monitor. It is also why the monitor was such a good price (a definite case of you get what you pay for here). So the unfortunate answer is that the monitor will never be satisfactory when used on the internet.

My screen on my labtop broke and its app white. my dog dropped it and i do not no if anything is wrong with the rest of it is there any way i can find out before i pay to fix the screen? it is my hp labtop


Connect an external monitor to the VGA port, look to see if there is a key to toggle between internal lcd and external monitor, on my lap top it is <FN><F5>, on my Dell it is <FN><F8>

if the display is normal then the problem could be the ribbon cable connector, the inverter, or the LCD. If the external display is bad also the the problem is the video card or if embedded, the mother board is bad.

DVI cable not working


If you still have your old monitor plug it back in for a bit and load the drivers for the new monitor (from the disk which came with the new monitor). Right click on your desktop and choose properties and set your display resolution to something like 1024 x 768. Shut down the pc and connect your new monitor to it with the dvi adapter. If it is recognised ok you can then set the resolution from 1024 x 768 to the recommended amount for your new screen. The refresh rate is also important as some lcd screens only work at a certain level. There should be an auto switch on the monitor and if you press this it sets the display to optimum, - or should do.
