Monitor display problem - patches of flickering dash lines

I have a HP lcd monitor HPvs17e. About six months back, due to blank screen (cannot boot), the repairman changed my nvidia GeForce grahics card to GeForce 7100GS and everything was OK. About two months back, I started getting patches of short repetitive dashed lines on my monitor display. On white background, the dash lines are pink. On other backgrounds it is different colour - example, green. It's worse while viewing videos online.

I scan my hard drive with anti virus, anti-spyware, did a disk cleanup, defrag, registry clean, and even did a system restore to a date before the problem started but didn't help at all. I even took out the graphics card to brush clean; uninstall and re-install the graphics software.
I changed the monitor, also using another video signal cable and I still get the same problems. The lines are getting worse (more). Attached is a screen shot of the display (green dash lines). Anybody can tell me what the problem is please.
If graphics card need replacement, how do I choose the right graphics card to replace?
Many thanks.

    Thank you for your information. Some time back I had tried installling the latest driver from nvidia and changing the resolution - has not helped. I am upset that the graphics card is not even one year old. I don't play online video games.

    I am not sure if I should buy the same type and get teh same problem later on. I read on a website about the option of updating the motherboard chipset drivers. I wonder if that would help.

    Really, Thank you again. I appreciate your time and knowledgeable advice. I am really impressed with your effort to help; it is quite rare.

    I'll have a look at the link you have given; and see if I understand or worth the time. I am not technically computer hardware or software savvy. I don't want ot mess up my PC and makes things worse. Already spent many, many hours over this problem. Maybe in the end, I'll just look for a compatible graphics card to replace and hope it works.



    Again, many, many thanks, Freetek!

It does sound as if the graphics processor of the video card has died but I suggest downloading the lastest driver for that card on the off chance it is simply a software hiccough.

If, after installing an updated driver it is still there, you might try changing the resolution via the Control Panel/Display, to see if the anomalies change in dimensions but this won't cure anything, only confirm that the card is at fault.

These cards are, on the whole, pretty reliable but your luck sure hasn't been very good.

    > I read on a website about the option of updating the motherboard chipset drivers.



    I can't advise you on that since the system board may have been made by a non-HP supplier.



    A freeware utility called the Belarc Advisor delivers 4-5 PAGES of incredibly detailed information about the hardware and software of your system and even checks to see if you have all the latest tweaks to crummy MS Windows and lists those missing.

    Now that is something I can recommend :-)



    http://www.belarc.com/free_download.html



    It should be able to identify the board manufacturer, a necessary step to check for downloads.



    BTW, I own thousands of bucks worth of excellent (older) HP test equipment but after trying to service a few HP-named systems, they are on my permanent blacklist.

    It took two new sets and the original 8-disk set to get enough usable disks/files together to reinstall the original software bundle. There were defective disks in the original set, then the 1st newly purchased ($80), then had to pay another $24 FedEx on the replacement set (#2).

    Not one of the three sets (24 CDs total) was 100% readable even in other systems.



    Good luck-

Has anyone ever seen such? This is a screen shot of my wifes HP Laptop. Fresh driver, updated DX, hooked it to a monitor and sent this to a few friends much smarter than me on computers. Lot of trouble shooting by direction but no results yet. Anything would be greatly appreciated.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

How do i fix a flickering screen problem of my HP Compaq 6735s laptop


The flickering could be a sign that your lcd screen is going bad and needs to be replaced. It could also be the video card inside the computer. Isolate the problem by connecting another monitor to the laptop. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the laptop. If the Borrowed monitor displays ok without flickering, then your video card inside the computer is good, but your lcd screen is bad. If the Borrowed monitor flickers like your lcd screen did, then your video card inside the computer is bad.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

Try tapping the back of the lcd screen's lid to see if the flickering stops, increases or decreases. It might be that the lcd cable located at the top on the back of the lcd screen is loose.Isolate the problem by connecting another monitor to the computer. You'll have to take the lcd apart to get to the video cable on the back of it.

Hpvs17e white backround is pink


hucknannie, Power down the pc and monitor. Then disconnect and reconnect the VGA cable a few times to the rear of the pc. then turn system back on and re-boot. If your "PINK" screen still there, then you may need to have unit refurbished with new "cold-cathode-fluorescent-lamps" or have the internal "switch- mode-power supply/ccfl-inverter-supply" inspected and repaired. Yes, before you do anything, visit this web blog about HP monitors!!! http://www.lesliewong.us/blog/2005/05/02/hp-pavilion-f1703-flat-panel-display-blackout-solution/ Read and make note that people are still visiting the blog even after 4 years!!

Blank HP w1907


If the power light does not turn color and stay's green on startup, it is not a power problem. It is most likely the inverter. If the unit is in warranty, send it out ASAP. Contact HP customer care by email and have the issue logged in.
If in warranty, they will send you a box by FedX second day and have repaired.
This is a 19" monitor and will not be worth paying for repairs if not in warranty.

Display problem


You could have a defective screen - a defective inverter or a CCFL lamp or simply the video cable needs reseating. After reseating the video cable and the problem is still there then :- To determine if you have a LCD screen or video card problem, read this and follow the instructions. Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case. The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills. Check out www.lcdparts.net for parts, repair service and DIY info.

Dell Inspiron 9400 display goes blank after a few minutes


If the issue occurs in the safe mode, then I'm suspecting a failure of the LCD backlight. (It warms up and quits) Also see if video stays on using an external monitor. If it does, then the LCD is most likely failing.

If video goes out on an external monitor as well, then the Video card is failing due to overheating. Make sure all vents are free of dust (Clean with canned compressed air) and the all fans are functional (Run the fan test in diagnostics) If fans check up, then video card is failure point. If fans fail diags, replace affected fan 1st

Monitor displays breifly then goes to blank screen


The power -inverter board probably needs an overhaul.
I redo many of these.
If the screen was pinkish or flickering before it finally got to this point, it is possible that a bulb has gone bad.
