Question about HP L1706 17" LCD Monitor

1 Answer

HP L1706 monitor with thin white/blue horizontral line

Our school recently purchased 28 HPL1706 monitors and to date 2 have developed a thin horizontal white line across the screen. On the first the line is 1/3 from the bottom of screen and on the second 1/3 from the top. The pointer appears to pass underneath this line and it is not a scratch. When monitor has no input line appears white and of different intensity in different 1/3s of the screen - we await HP's comments but don't expect much being a school in Malawi'- I always said we should have gone with Acer's as we have had no problems from previous monitors.

White line across screen


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.

Take it to a repair shop.

My Dell monitor developed a thin, dark line horizontally across the screen. Within three months, a second line appeared. I can view the screen, but must look above or below the lines at times. Any idea...


this occurs very commonly in all LCD monitors... this is because each and every cells in the LCD monitor are energized by the vertical and horizontal electric fields placed around the frame of the monitor... if a particular field does not gives the power to the associated cells to it, then the entire line of cells will not operate and together they looks like a single line...This is what happened in your case...


have a look at my tips for replacing the LCD screens on monitors, by clicking here....

Thin line across computer screen


Your Display cable (inside your monitor) needs to be replaced.

I would look on ebay to try and find the part and then take it to a local tech to replace it for you as I would not recommend anyone take apart a monitor (LCD OR CRT) if you had never done so before.

OR, Buy a new monitor.

Horizontal lines on Screen


Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

Monitor goes black with a white horizontal line across the middle of the screen


Check to see that the monitor cable is correctly installed. Also, make sure you have the most up-to-date drivers installed for your graphics adaptor card(both ATI and Nvidia carry catch-all driver programs to keep you up to date.) Tighten the cable screws of course, to make sure the monitor cable isnt just wiggling in its seating.
